A griddle is the one outdoor cooking appliance most likely to be left sitting in the weather, and the cover you buy for it matters more than most buyers expect. After going through the construction specs, seam details and owner feedback across ten of the best griddle covers for outdoor griddles on the market, the Blackstone 36 Inch Griddle Cover is the one I would put on a 36 inch flat top and forget about. For a different griddle, the deciding factors change, and that is where most of the mistakes happen.
The category is messier than it looks. A hooded 36 inch cooking station and a hoodless 36 inch flat top need completely different covers, and a 17 inch tabletop griddle cannot use anything built for a 56 inch outdoor kitchen station. Fabric weight alone does not decide whether water gets in. Sealed seams, a real strap system and somewhere for condensation to go decide that, and those three details are what I weighted most heavily across this roundup.
One thing to say up front: this is not a roundup built from a winter of my own griddles standing in snow. It is built from published construction specs, seam and coating claims, warranty terms, and roughly 120000 owner reviews across the ten covers below. Where owners report a specific failure, I say so. Where a manufacturer claims something the spec sheet does not prove, I flag it. If you are still choosing the griddle itself, our flat top griddle guide and backyard griddle roundup cover the units these covers are sized for.

Top 3 Best Griddle Covers For Outdoor Griddles (October 2026)
Three covers stood out once fit, weather construction and owner feedback were weighed together. The Blackstone 36 Inch cover takes the overall spot on a 29096-review base and a form-fitted buckle closure that anchors under the base. The iCOVER 36 inch cover is the volume option with the widest stated compatibility list. The Unicook 28 inch cover wins on one detail almost nobody else builds in, a support pole that lifts the cover off the oiled cooking surface.

What is the best griddle cover overall? For a 36 inch hoodless griddle, the Blackstone 36 Inch Griddle Cover is the strongest all-round choice: 600D polyester, double-layered reinforced stitching, a form-fitted silhouette and poly-resin buckles that clip under the griddle base, backed by 29096 owner reviews. The deciding criteria are fit accuracy first, then sealed or taped seams, then a strap system that survives wind, then vents that let condensation escape.
1. Blackstone 36 Inch Griddle Cover – Best Overall for the 36 Inch Platform
- Form-fitted to the 36 inch Blackstone cooking station
- 600D polyester resists fading and cold cracking
- Buckle closure clips under the griddle base and holds in wind
- Hose-cleanable surface
- 29096 owner ratings to draw on
- Listed dimensions are package size not installed size
- Fits only the 36 inch configurations it names
This is the cover I keep coming back to for the 36 inch platform, and the reason is the buckle rather than the fabric. The poly-resin buckles clip underneath the griddle base, which means the cover is held from below rather than cinched from outside. On a freestanding cart that matters, because a cover that relies on tension alone is the first thing a gust lifts.
Construction is 600D polyester with a water-resistant coating, double-layered with reinforced stitching. Reviewers consistently describe fabric that survives a full season of sun and cold without cracking, which is the specific failure that forces people into a second cover a year later. It is also hose-cleanable, so bird droppings come off with a hose rather than a scrubbing session.
The fit is custom-designed for the 36 inch griddle with a shelf attached and for the tailgater, and reviewers repeatedly call out that it looks fitted rather than draped. That is a real difference in a backyard, where a sagging tarp reads as neglect. Owner feedback also notes the cover is a model-specific fit, so confirm your griddle matches the listed configurations before you commit.
Two things to know before buying. The published dimensions on this listing are package dimensions, not the installed cover size, so do not use them to check clearance. And the protection level is water-resistant rather than fully sealed, which is a sensible engineering choice for a breathable cover but means standing water on the top can still work its way in over a long storm if the cover is not cinched.
What to check before you order this cover?
Check your griddle against the stated fit, because a shelf configuration changes the shape the cover expects. Then check where the buckles attach. They need a clear run of base to clip onto, and on a cart with a cluttered lower shelf that is not always available.
Where it falls short?
It does not cover a hooded 36 inch station, and it is not the answer for anyone running a 36 inch griddle with a canopy above it. Owners who needed that protection ended up with a station cover instead, which is a different product at a different size and a different cost.
2. iCOVER 36 Inch Flat Top Cover – Widest Compatibility, Biggest Review Base
- Largest stated compatibility list in this roundup
- Covers Blackstone Camp Chef and Weber 4-burner flat tops
- Buckle straps and drawstring double up against wind lift
- Hose-down cleanable water-repellent finish
- Lowest average rating here at 4.4 with a 5 percent one-star share
- Does not fit the 36 inch Blackstone ProSeries
- Lighter fabric than heavy canvas alternatives
With 51637 ratings, this is the most reviewed cover in the roundup and the one most people will stumble across first. The stated envelope of 65 by 22.5 by 26 inches covers a wide band of hoodless four-burner flat tops, and the compatibility list names specific Blackstone, Camp Chef and Weber models rather than gesturing at the category.
Anchoring is doubled up. Side buckle straps hold the upper body and a drawstring cinches the bottom hem, so there are two independent things resisting wind lift. That combination is what prevents the billowing cover complaint that comes up constantly in cover forums, where a single strap system lets the fabric act like a sail.
Construction is lightweight oxford polyester with a water-resistant PVC coating and a UV-resistant outer vinyl layer, with double-reinforced corners at the sharp elbows. The elbows are where a cover actually tears, because that is where fabric folds hardest every time you put it on and take it off.
The trade-off is fabric weight. Owners who compared it to heavy canvas describe it as thinner, and it carries the lowest average rating in this group with a 5 percent one-star share. It also does not fit the 36 inch Blackstone ProSeries, so if that is your griddle, this one is out.
Why this one suits a first cover?
Nothing about the construction is exotic, which is the point. Oxford with a PVC coating, buckles and a drawstring, no support pole and no premium hardware. It does the ordinary job across the widest range of griddles, and the review volume means replacement parts and fit answers are easy to find.
Where the compromises show?
Light fabric is the honest weakness. In high wind or under a tree that drops branches, a thinner cover abrades sooner, and the fit exclusions are specific enough that you need to check your exact model rather than assume from the size class.
3. ATHLEEGOUS 36 Inch 600D Cover – Best Where the Sun Is the Problem
Griddle Cover for Blackstone 36″ 1528 Without Hood, 600D Waterproof
- Reinforced 600D Oxford rated above lighter 210D and 420D builds
- Heat-resistant PU coating limits heat buildup under strong sun
- Triple-strap secure fit resists shifting in wind
- Waterproof coating with reinforced stitching limits pooling
- Not compatible with the 36 inch Blackstone ProSeries
- Hook-and-loop straps can degrade after a few seasons of UV exposure
Southern and southwestern patios do not fail covers with rain, they fail them with UV. This one is built around a heat-resistant PU coating that limits heat buildup and blocks UV rays, which is the specific claim that separates it from a standard black polyester shell in full sun.
Fabric is reinforced 600D Oxford, positioned in the listing above 210D and 420D constructions. The 66.5 by 22.5 by 26 inch envelope is aimed at the standard 36 inch Blackstone without a hood, and reviewers confirm the fit is snug rather than baggy on those units.
Anchoring uses adjustable side straps plus an additional bottom strap, so three points resist shifting. That is more holding power than most covers in this price band, and reviewers report the straps generally stay put once set.
The stitching is reinforced and combined with the waterproof coating to keep water from pooling at seams, which is where a cheaper cover quietly fails. My reservation is the hook-and-loop closures. They feel good at first and tend to stiffen and lose grip after a few seasons of direct UV, and this is a cover people leave out permanently.
When to pick this one?
Choose it when your griddle sits in direct sun for hours most days and rain is an occasional problem. The heat and UV resistance is the point, and if you live somewhere the cover will cook as hard as the griddle does, that matters more than raw weight.
What to watch?
It excludes the 36 inch ProSeries, and the hook-and-loop straps are the part most likely to need replacing. Expect to reset or swap the straps every couple of seasons rather than assuming they will last as long as the fabric.
4. Unicook 28 Inch Griddle Cover – Best Value With the Support Pole
- Support pole stops water pooling and contact with the oiled surface
- Taped double-stitched seams hold up in heavy rain
- Handles plus fastening straps make fitting simple
- Long-term durability reported across multiple seasons
- 28 inch size does not fit the 28 inch ProSeries or 1856
- Some variants lack handles or cinch straps
- Hose clean only
- not machine washable
The support pole is the reason to look at this cover twice. It raises the centre of the cover so water runs off instead of pooling, and it keeps fabric from lying against the oiled cooking surface. Almost every other cover in this roundup solves wind and rain but not the standing-water problem.
At 4.8 stars across 7930 reviews, it also punches above its weight. Reviewers report the cover staying in place through hail and high wind, and several describe replacing a four-year-old unit with this one, which is a durability signal no spec sheet provides.
Seams are the other story here. Double-stitching combined with sealing tape is the construction that separates this from a stitched-only cover, and it is why heavy rain does not produce the seep-through owners report with lighter fabric. The outer fabric is high-density vinyl-coated and described as fade and UV resistant.
The 28 inch version measures 45 by 23 by 25 inches and suits most brands of 28 inch single-shelf griddles, including Blackstone and Nexgrill. It does not fit the 28 inch ProSeries or counter-height shelf models such as the 1856, so shelf height is the detail to verify, not just width.
Why the pole matters more than it sounds?
A flat cover on a flat griddle is a shallow tray. Standing water sits there, and repeated wet and dry cycles on a coated steel surface are exactly what causes pitting. Lifting the centre breaks that tray, so this cover does something structurally different rather than just being thicker.
What to confirm first?
Measure your shelf height and your griddle length including any front shelf, then compare against 45 by 23 by 25 inches. And expect to hose it clean rather than put it in a machine, which is fine but worth knowing if your storage is small.
5. NettyPro 36 Inch Griddle Cover – Best for Wind, Snow and Condensation
NettyPro Griddle Cover for Blackstone 36 inch Griddle, Waterproof UV Resistant 4 Burner Flat Top Gas Grill Cover 36″ Cooking Station, Black
- Generous 67 by 27 by 32 inch envelope fits griddles up to those dimensions
- Buckle and strap hardware holds better than hook-and-loop in wind
- Covered front vent reduces condensation under the cover
- Size range spans multiple griddle formats
- Hooded and hoodless sizes are separate variants
- Coloured variants reportedly fade after several years of sun
This is the most generously sized cover here, at 67 by 27 by 32 inches, and that envelope is the reason it keeps showing up for people with side shelves and hood structures who cannot find anything that fits. If your griddle is awkward, start here.
Owners single out the hardware. Two adjustable side straps and four bottom buckles give five anchoring points, and reviewers repeatedly say the buckle system holds in exposed locations where hook-and-loop covers do not. In snow country the bottom buckles are the difference between a cover that survives a storm and one that ends up in a neighbour’s yard.
Construction is high-density PU-coated UV-resistant ripstop with fully covered seam tape and double stitching at edges and connections. Taped seams across the whole seam line, rather than at a few stress points, is a more serious waterproofing approach than most covers in this round use.
The wide covered front air vent is the detail that separates it from a sealed bag. That vent exists to let condensation escape, which matters because a sealed cover over a griddle that cools overnight will collect moisture against the steel. Long-term fade on coloured variants is the reported weak point after about five years.
When this is the right pick?
Pick it for a 36 inch griddle with side shelves, a canopy structure, or exposure to high wind and heavy snow. The extra volume means a loose-looking fit is intentional rather than a sizing error, and the taped seams plus vents handle both the water coming in and the water already inside.
What to double check?
Hooded and hoodless versions are separate products with separate ASINs, so make sure you are on the one matching your configuration. If you want a colour other than black, expect visible fading over several seasons.
6. Blackstone 5482 Hooded 36 Inch Cover – Highest Rated for Hooded Stations
- Highest rating in this roundup at 4.9
- Reinforced stitching resists leaks and tearing
- Cinch straps and end latches keep the cover locked down
- Reported to still hold up after two years of continuous exposure
- Covers 36 inch griddles with a hood only
- Listed dimensions are package size not fitted size
- Hoodless 36 inch needs a different product
At 4.9 stars across 5264 reviews with a 92 percent five-star share, this is the highest-rated cover here, and the reason is specificity. It is built for the 36 inch griddle with a hood, and owners describe a precise fit on that platform rather than an approximation.
It weighs 6 pounds, the heaviest cover in the roundup, which is a reasonable indicator of how much material is in the shell. Anchoring is cinch straps and plastic clips, a combination that pulls tight and stays tight, and owners report latches that continue holding in high wind.
The fabric is heavy-duty 600D polyester with a weather-resistant coating and reinforced stitching to prevent leaks and tearing. It carries a 1-year warranty from Blackstone, which is worth noting because most aftermarket covers in this category do not include one at all.
The recurring owner theme is longevity. Reports describe the cover still looking good after two years of continuous outdoor exposure, which is the metric that matters if you are not planning to buy another one. Again, published dimensions are package dimensions, so measure your griddle rather than trusting that field.
Why the hood matters for fit?
A hood changes the silhouette completely. It adds height and a projecting shape at the back, so a cover built for a flat hoodless top either will not reach or will sit loose and collect water. If your griddle has a canopy, this is the correct product and the hoodless covers above will not do the job.
When to buy something else?
If your 36 inch griddle has no hood, this is the wrong cover and the wrong price for the job. Go back to the hoodless options, and note that the shape difference is also why hooded and hoodless versions are listed separately across this whole category.
7. Porch Shield 28 Inch 600D Cover – Best for Condensation Control
Porch Shield 600D Waterproof Outdoor Griddle Cover 28 inch
- Fits 28 inch single-shelf griddles and 2-burner flat tops up to 46 by 24 by 28 inches
- Click-close straps and bottom buckles hold in wind
- Large air vents reduce condensation under the cover
- Ribbon-woven handles make fitting and removal easy
- 28 inch sizing excludes 36 inch and 40 inch griddles
- Model number and part number listings differ and confuse fit checks
Humid climates produce a specific failure: a griddle that cools overnight under a sealed cover sweats, and the trapped water sits against the steel from underneath. This cover is built around that problem, with large air vents as a stated feature rather than an afterthought.
At 4.7 stars across 3417 reviews, owner feedback centres on the strap and buckle system, the vents and the handles. The click-close side straps plus bottom buckles anchor at two levels, and the heavy ribbon-woven handles make it practical to put on and take off repeatedly, which is a real consideration if you cook outside often.
Material is 600D polyester with a waterproof undercoating and UV-resistant treatment, and the seams are double-stitched and sealed. The undercoating is worth noting because a coating on the inside face blocks moisture from escaping back outward, which is the opposite of what you want in high humidity.
The envelope is 46 by 24 by 28 inches, aimed at 28 inch single-shelf Blackstone griddles and most 2-burner flat tops. It does not stretch to 36 inch or 40 inch units. One oddity to watch: the model number and the manufacturer part number in the listing do not match, which makes fit verification a little slower than it should be.
When venting is the deciding factor?
If your griddle sits where nights are warm and damp, ventilation matters more than raw waterproofing. A cover that blocks rain but seals in moisture can leave you worse off than no cover at all, and the vents here are the mitigation for that.
Where it will not work?
It is a 28 inch single-shelf cover, so it stops at 46 inches of length. Anything from 36 inch griddles upward needs a different envelope, and if your griddle is on the large side this is not the product to stretch.
8. Blackstone 5483 28 Inch Hooded Cover – Best for 28 Inch Griddles With a Hood
- Thick 600D fabric owners compare to backpack material
- Semi-elastic clinch straps pull tight so gusts cannot lift a corner
- Water beads on the surface and the interior stays dry
- Generous fit covers the propane tank and front shelf
- Reported to outlast cheaper covers that failed within a year
- Runs long on some griddles so the unit may need moving with the cover on
- New fabric has stiff creases that relax after a day of sun
- Intended for 28 inch griddles with a hood only
Owners describe this fabric as closer to backpack material than to a big-box tarp, and that comparison comes up often enough to be useful. At 4.8 stars across 3573 reviews it sits among the best-rated covers here, and the recurring comment is that it replaced a cheaper cover which had failed within a year.
The detail that matters most is the semi-elastic clinch straps and clips. Elastic pulls the cover snug against the shape of the griddle, so a gust cannot find a loose corner to grab. Several owners specifically mention water beading on the surface and the interior staying dry, including around the hood hinge.
Construction is heavy-duty 600D polyester with a water-resistant PVC coating, described as fade resistant, and it carries a 1-year limited warranty. At 0.45 kg it is light for how much surface area it covers, which is another way of saying the fabric is efficient rather than bulky.
The generous envelope covers the propane tank and front shelf under one roof, which is convenient and also a fit risk. Owners note it runs long on some griddles to the point where the unit has to be moved with the cover on, and the new fabric arrives with creases that take a day of sun to relax.
When a generous fit is an advantage?
If your setup keeps the propane tank mounted under the front shelf, a cover that reaches both is much more useful than a cooktop-only shell. You are not uncovering a half-protected appliance every time you cook, and the shelf does not weather uncovered.
What to plan around?
Plan for the length. If the cover runs past the wheels, you will be moving the whole griddle, and that changes how often you are willing to put it on. Also allow the new fabric a sunny day before you judge the creasing.
9. Turtle Life 46 Inch Flat Top Cover – Best for Wider 2 and 3 Burner Setups
Turtle Life BBQ Grill Cover, 46 Inch Heavy Duty Waterproof Barbecue Gas Grill Covers for Flat Top Griddle, Anti-Fading Cover for Gas Grill, Black
- Fits flat top griddles and 2-3 burner grills up to 44 inches wide
- Included storage bag for off-season folding
- Reported still waterproof and tear-free after a year of Colorado weather
- Holds position through storms on the connected straps
- Fabric is thin with one report of thinning and rip spots after about 18 months
- Sizing runs large and can look loose on smaller grills
- Occasional fit misalignment traced to grill shape
This is the one to look at if your griddle is not a Blackstone or a Weber but a Royal Gourmet, a Nexgrill or something of that shape at 44 inches wide or under. The 47 by 24 by 39 inch envelope is the tallest in this roundup, which is why it works on setups with uprights and taller back sections.
Anchoring is unusually thorough for a cover in this band. Bottom eyelets with stoppers plus a tie-down rope give multiple fixed points, and owners say the cover holds position through storms on the strength of those straps alone. There are also ventilation holes to reduce trapped moisture, which fits the same logic as the vented covers above.
Material is heavy-duty Oxford with an upgraded PVC coating, rated waterproof, dustproof, rip resistant and UV resistant. It includes a storage bag, which sounds minor and is not: a cover that folds down small enough to put in a bag is far more likely to actually come off in summer.
The main weakness in owner feedback is fabric thickness, with reports of material thinning and rip spots developing after about a year or two of exposure. Sizing also runs large, so on a smaller griddle the cover looks loose, and occasional fit issues trace back to the shape of the grill rather than the cover.
Why the storage bag matters?
Anyone who lives with a griddle in full sun will take the cover off for the summer. Covers that stay folded in a garage corner tend to end up cracked from being crammed for months, and a bag makes it a two-minute job instead of an argument with yourself.
Where it wears out?
Expect thinner fabric than the 600D covers here. On a griddle that sees a full day of sun, plan to inspect it annually at the seams and elbows, because that is where the thinning reports start.
10. NOELIFE 17 and 22 Inch Cover – Best for Tabletop Griddles
Griddle Cover for Blackstone 22″ 17″ Grill with Stand, Cover Only
- Sealed seam tape with waterproof inner and outer layers
- Hook-and-loop side straps plus an adjustable bottom buckle
- 600D high density fabric resists tearing
- Designed for 22 inch and 17 inch griddles with hood and stand
- Excludes the 22 inch Model 2063 and the ProSeries 22 inch
- Cover only with no stand or hardware included
- Listed dimension fields are placeholder values
Tabletop griddles get left outside more than any other size, because they are easy to move and nobody wants them in a garage. This cover is built for the 17 inch and 22 inch griddles that come with a hood and a stand, which is the configuration most tabletop owners are running.
Waterproofing here is doubled up. Waterproof outer and inner material combined with sealed seam tape gives two independent barriers, which is a more serious approach than a single coated face and is the detail owners most often confirm. At 4.6 stars across 4179 reviews, the feedback is consistent on that point.
Anchoring combines hook-and-loop straps on both sides with an adjustable bottom buckle strap, so the hem is secured independently of the body. Fabric is 600D high-density, described as waterproof and UV proof, and it carries a 1-year warranty.
The exclusions are the real story. It does not fit the 22 inch Model 2063, the ProSeries 22 inch, the on-the-go tailgater 17 inch combo or the Duo 17 inch combo. It is also cover only, so no stand is included, and the listing’s dimension fields contain placeholder values rather than measurements, which means you must measure your own unit.
Before you buy, identify your exact model
With tabletop griddles, the model number is everything. The 17 inch and 22 inch families have several visually similar variants, and the exclusions here are specific model numbers rather than general sizes. Check the plate on your griddle and confirm it before ordering.
What to watch over time?
Hook-and-loop straps on a permanently outdoor cover are the part to inspect each season. They stiffen under UV exposure, and while the bottom buckle is a mechanical strap that will outlast them, the upper attachment is what holds the body down in a gust.
How We Chose the 10 Best Griddle Covers?
We compared published construction specifications, warranty terms and owner review patterns across ten covers, then ranked them on five weighted criteria. No cover made the list on brand name alone.
Fit accuracy (30 percent). Does the cover name the specific griddle models it fits, and does the stated envelope give you enough room without being baggy? Covers with placeholder dimension fields lost points here automatically.
Weather construction (25 percent). Fabric weight in denier, coating type, and above all whether the seams are taped and double-stitched or stitched only. A cover that is waterproof on the face and open at the seam is not waterproof.
Wind anchoring (20 percent). The number and type of attachment points. Buckles and drawstrings score above hook-and-loop because they do not stiffen under UV, and covers with bottom anchoring score above covers with none.
Condensation handling (15 percent). Air vents, elevated covers or support poles that keep water off the steel. A sealed cover over a cooling griddle collects the exact moisture it was bought to prevent.
Owner feedback (10 percent). Volume and specificity of reviews, with attention to what owners actually complain about rather than the star number alone.
Two things we deliberately did not weight: appearance, and how many size options a listing offers. Both matter to buyers, and neither predicts how well a cover keeps water off a steel surface after two winters.
Griddle Cover Buying Guide: What Actually Keeps Water Out?
Most cover complaints trace back to one of five things: the wrong size, unstitched seams, no wind anchoring, no ventilation, or covering a griddle that was still warm. Here is how to avoid each.
1. Measure your griddle, and measure it properly
Get three numbers: the width across the widest point including side shelves, the length front to back including the front shelf and any handle, and the height at the tallest point including a hood or upright. Then add two inches to each measurement and compare against the cover envelope, not against the griddle size printed on the box.
Griddle size labels are nominal. A 36 inch griddle with a shelf attached and a canopy above it is a different shape from a bare 36 inch flat top, and this is why hooded and hoodless covers are separate products in every brand’s catalogue. If you are still picking the griddle, our outdoor griddle cart guide covers the shelf and shelf-height configurations that change cover dimensions.
2. Denier and coatings, decoded
Denier measures fabric density. 210D is thin, usually a single-layer shell that is fine for a griddle stored under a roof. 420D is the common middle grade. 600D is where most of the covers here sit, and it is the point where reinforced stitching starts to matter. 800D and 900D exist and are heavier, but weight alone does not waterproof anything.
Coatings come in two families. PU coating is a thin polyurethane layer, lighter, often heat resistant and good at blocking UV. PVC backing or vinyl coating is heavier, more water resistant and more prone to stiffening and cracking over years of UV exposure. Solution-dyed fabric holds colour through the fibre rather than the surface, which is why it fades last. For a griddle that lives in full sun, PU or solution-dyed is the better long-term answer.
3. Waterproof versus water-resistant, and why seams decide it
Water-resistant means the face fabric sheds water. Waterproof means the whole assembly, seams included, keeps it out. Almost every cover in this roundup is water-resistant at the face, and the honest difference between them is what happens at the stitching.
A stitched-only seam is a line of holes. Water finds it eventually, usually from the first sustained downpour. A taped or sealed seam closes that line, and that is the single detail forum owners consistently point at when comparing covers. The Unicook, NettyPro, NOELIFE, Porch Shield and ATHLEEGOUS covers all describe taped or sealed seams. The iCOVER and Turtle Life covers describe coatings and reinforced corners rather than full seam taping.
4. Straps, buckles and drawstrings: beating the wind
A cover with no bottom anchoring will lift. That is not a defect, it is aerodynamics, and it is why a billowing cover ends up against a fence. Look for at least one bottom attachment in addition to the side straps.
Among attachment types, buckles and drawstrings hold better over time than hook-and-loop. Hook-and-loop is comfortable and easy to adjust in the moment, but UV exposure stiffens the loops and they lose grip, which is a real complaint on covers that stay outside permanently. The BH-style clip system used on the hooded Blackstone covers is a third option and works well on that specific platform.
5. Vents, and why a cover can cause the rust it prevents
There are exactly two common reasons a griddle rusts while covered. The first is covering a griddle that is still warm, which traps steam that condenses on the cold steel overnight. The second is a fully sealed cover trapping humidity from warm nights, fogging up and dripping onto the cooktop.
Both are avoidable. Let the griddle cool completely before you cover it, and choose a cover with vents or a support pole. The NettyPro, Porch Shield and Turtle Life covers all carry vents as stated features. The Unicook cover solves it differently, with a support pole that lifts the centre so water cannot sit on the surface at all.
6. UV resistance and sun fade
Black fabric still fades, and faded fabric is usually fabric that has been UV-damaged. Look for an explicit UV-resistant claim and prefer PU or solution-dyed fabrics over a PVC-backed face if your griddle gets direct afternoon sun. Check coloured variants especially, because pigment fades faster than black dye and NettyPro owners report visible fade on non-black versions after several years.
7. Matching by griddle size class
For 17 inch and 22 inch hooded griddles on a stand, the NOELIFE cover is built for that shape. For 28 inch single-shelf griddles, the Unicook and Porch Shield covers are the two strongest fits, and the Blackstone 5483 if yours has a hood. For 36 inch hoodless flat tops, the Blackstone 36 inch, iCOVER, ATHLEEGOUS and NettyPro covers cover the ground. For a 36 inch griddle with a canopy, the Blackstone 5482 is the correct product. For wider 2 and 3 burner griddles from other brands, the Turtle Life cover at 47 by 24 by 39 inches handles the shape that the others cannot.
8. Living with a griddle outdoors year-round
You can leave a griddle outside under a cover, provided three things are true. The griddle is completely cool before covering, the cover has some way for trapped moisture to escape, and the cover is anchored at the bottom as well as the sides. Season and dry the cooking surface first, then cover. One owner in Connecticut seasoned and covered a griddle for the winter and found the surface in good condition afterwards, which matches what the physics predicts.
Never cover burners, burner control knobs or a propane tank connection while the appliance is hot, and never put a cover over a live or recently used griddle. If your griddle lives under a pergola or patio roof, the risk is lower but not zero: falling leaves, sap, bird droppings and wind-driven rain still reach the surface, so a cover remains worthwhile. Our camping griddle guide covers the setup where a griddle moves between patio, RV and tailgate, where a lightweight cover that folds into a bag is the practical choice.
9. Pests, and the silicone mat workaround
Mice getting onto a stored cooktop is one of the most common problems reported in griddle forums, and it is a hardware problem rather than a cover problem. A fabric cover does not stop a determined rodent. The fix owners report actually working is a silicone cooktop mat, which is why silicone mats surface so heavily in griddle communities even though almost no editorial roundup covers them.
The practical combination is a silicone mat under the fabric cover. The mat protects the seasoned surface from scratching and contact, and the fabric cover handles rain, sun and wind. This is a two-product answer to a two-part problem, and the same approach is used for storage covers on other outdoor equipment, as we cover in our motorcycle cover guide.
Frequently Asked Questions
What is the best griddle cover?
For a 36 inch hoodless griddle, the Blackstone 36 Inch Griddle Cover is the strongest all-round choice, with 600D polyester, double-layered reinforced stitching and poly-resin buckles that clip under the griddle base. The real deciding criteria are fit accuracy first, then taped or sealed seams, then a strap system that includes a bottom anchor, then vents that let condensation escape. Hooded 36 inch stations need a station cover instead.
Can you leave a Blackstone griddle outside with a cover?
Yes, provided you let the griddle cool completely before covering it and choose a cover that can vent. Covering a warm griddle traps steam that condenses on the cold steel, and a fully sealed cover traps overnight humidity, both of which cause the rust the cover was meant to prevent. Season and dry the cooktop, cover it cool, and use a cover with air vents or a support pole.
What is the best material for an outdoor grill cover?
For a griddle that lives outdoors, high-density 600D polyester with a PU coating or vinyl coating is the practical best choice. 600D is the point where reinforced stitching and tearing resistance start to matter, and 210D or 420D shells are too thin for permanent exposure. PU coating is lighter and better in direct sun, while PVC backing is heavier and more water resistant but stiffens over time. Sealed seams matter more than the coating choice.
What is the best waterproof grill cover?
Look for taped or sealed seams combined with a coated face fabric, not the word waterproof on its own. A cover that is water-resistant on the face but stitched only at the seams will eventually seep, which is the most common complaint about covers sold as waterproof. Among the covers reviewed here, the Unicook, NettyPro, NOELIFE, Porch Shield and ATHLEEGOUS models all describe taped or sealed seam construction.
What size griddle cover do I need?
Measure the widest point including side shelves, the full front-to-back length including the front shelf, and the tallest point including any hood, then add two inches to each and compare against the cover envelope. Match by model number where possible, because hooded and hoodless versions of the same nominal size are different products. Covers here range from a 45 by 23 by 25 inch envelope for 28 inch griddles up to 67 by 27 by 32 inches for 36 inch stations with shelves.
How do I stop my griddle from rusting outside?
There are two causes, and both involve moisture from inside the cover rather than rain from outside. The first is covering a griddle that is still warm, so let it cool fully first. The second is trapping humidity under a sealed cover, so choose one with air vents or a support pole that lifts the centre away from the cooking surface. Keeping the cooktop seasoned and oiled before long storage adds a further layer of protection.
The Best Griddle Cover Is the One That Matches Your Griddle
The best griddle covers for outdoor griddles in 2026 are not chosen by brand or by star rating, they are chosen by fit. Match the shape and the height of your griddle first, confirm the seams are taped rather than stitched only, and make sure the cover anchors at the bottom and can let moisture out. Get those three right and almost any well-made cover will outlast its griddle.
For a 36 inch hoodless flat top, start with the Blackstone 36 Inch Griddle Cover. If yours has a canopy, the Blackstone 5482 is the correct product. If you are covering an 28 inch single-shelf griddle, the Unicook cover with its support pole solves the water pooling problem that nothing else in this roundup addresses. Measure first, then pick, and check the model numbers before you order.
