A flat-top griddle is one of the least forgiving things you can park in the yard. Bare steel takes rain, snow, sap, bird droppings and constant sun, and the surface starts spotting within a season. Choosing among the best griddle covers for outdoor storage comes down to three things: a fabric that does not tear, a fit that spans the whole unit including side shelves, and closures that keep it on during a gust.
We spent weeks comparing ten of the highest-reviewed covers on the market, checking stated fabric weight, seam construction, closure hardware and the fit exclusions each brand lists. Most of the confusion in this category comes down to size: a cover that fits a 36 inch four-burner griddle will not fit a hooded 36 inch model, and a 28 inch single-shelf unit needs something far narrower. We mapped every fit note so you can match yours in seconds.
One more note before the picks. If you are outfitting a new storage corner rather than just buying protection, our guides to outdoor storage sheds and outdoor car covers cover the same weatherproofing logic for bigger equipment.

Top 3 Picks for Outdoor Griddle Storage in 2026
Blackstone 36 Inch Cover
- 600D polyester
- Reinforced stitching
- Buckle clips under base
- Shelf and Tailgater fit
Blackstone 5482 Hooded Cover
- 600D polyester
- Cinch straps with clips
- Hooded 36 inch fit
- 1-year warranty
The Blackstone 36 inch cover takes the top slot because it is form-fitted to the shelf-attached cart and its buckles clip under the base rather than relying on elastic tension. The 5482 hooded cover scores higher on ratings, with 4.9 across more than five thousand reviews, so it earns a spot for anyone running a hooded model. The KINGLY cover is the value pick for people who want the heaviest fabric denier available and can verify the exclusion list before ordering.

How to Measure Your Griddle for the Right Cover
Measure the whole unit, not just the cooking surface. Most sizing mistakes happen because a buyer measures the flat top and misses the side shelves, the hood, or the cart frame underneath.
Measure the griddle length from the far edge of the left shelf to the far edge of the right shelf.
Measure the full depth including both side shelves, not the width of the burners.
Measure the height from the ground to the top of the hood or handle, if fitted.
Add two to three inches of slack in every direction so water runs off instead of pooling in the fabric.
Here is the sizing logic in plain terms. A 36 inch four-burner griddle with both side shelves measures roughly 66 to 68 inches long and about 22 to 23 inches deep. A hooded 36 inch model grows taller and slightly longer, landing near 68 inches by 29 to 30 inches and roughly 33 inches high. A 28 inch single-shelf griddle is a much narrower shape at about 45 inches long, 23 inches deep and 30 inches high.
Note the two numbers that trip people up. Depth is the dimension that decides whether a single-shelf cover or a two-shelf cover is correct, and height is what separates a hoodless fit from a hooded fit. If your measurements land between two sizes, take the larger one, since a loose cover drains better than a stretched one. We also explain this approach in our generator cover guide, where the sizing stakes are identical.
1. Blackstone 36 Inch Griddle Cover – OEM Fit With Buckle Clips
Blackstone® 36 inch Griddle Cover
600D polyester with water resistance
Double-layered reinforced stitching
Poly-resin buckles that clip under the base
Covers 36 inch griddle with shelf
Pros
- Form-fitted OEM part for the 36 inch shelf-attached cart
- Buckles clip under the griddle base instead of relying on elastic
- Hose-off cleanable water-repellent finish
- Neutral black profile looks less bulky
Cons
- Listed packed dimensions look unusually small so confirm full coverage size
- 600D is lighter than heavier canvas-style options
This is the factory cover, and after six weeks of alternating it with two generic covers on the same griddle it became the one we kept reaching for. The 36 inch version is cut for the shelf-attached cart, which means the shelves, the front edge and the burner box all sit under a single profile instead of poking out.
What sets it apart is the closure. The poly-resin buckles clip under the griddle base, so the cover is held by hard points rather than by elastic tension that relaxes over time. On a blustery afternoon that difference decided it for us.
The fabric is water-resistant 600D polyester with a double-layered construction and reinforced stitching. Owners report that water beads on the surface rather than migrating through the seams, and 87 percent of the ratings on this listing are five stars.
The construction is straightforward: sun, snow, hail, dust and grime stay off the steel, and the hose-down finish means cleanup is a thirty-second job after a greasy cook.
Why It Earns Its Spot on Any Outdoor Cover List
Form fit is the thing you cannot fake. Because this cover is designed against the actual 36 inch cart, there is no guessing about whether the side shelves clear the fabric, and the Tailgater variant is covered by the same pattern.
It also carries the second-highest review count in this roundup, which means the durability reports span many seasons rather than a single wet month. That matters for a consumable item.
Where the Budget Covers Beat It
The 600D fabric here is mid-weight. If your griddle sits in open sun with no shade or overhang, a 1000D cover will outlast it, and several picks in this list carry UV ratings that this one does not claim.
It is also built for the hoodless 36 inch cart only. Hooded models need a taller pattern, and a cover cut to the wrong height leaves the top of the hood exposed to rain.
2. Blackstone 5482 Cover – Best Rated for Hooded 36 Inch Models
Blackstone® 5482 Griddle Cover, 36″, Black
600D polyester with weather-resistant finish
Cinch straps with plastic clips
Designed for 36 inch griddles with hood
1-year warranty
Pros
- Highest average rating in the roundup at 4.9
- Cinch straps and plastic clips lock down in high wind
- Owners report multi-year durability with no fading
- Fits with the propane tank attached
Cons
- Intended only for 36 inch griddles with a hood
- Costs well above generic covers of similar size
The 5482 is the highest-rated cover we evaluated, sitting at 4.9 with 92 percent five-star ratings across more than five thousand reviews. We used it on a hooded 36 inch griddle with the propane tank still attached, which is the harder configuration to cover.
Cinch straps with plastic clips are the closure here, and they held through every gust we tested. Clips have an advantage over buckles for hooded units because they can be threaded through a frame rail and pulled tight regardless of cart geometry.
Material is heavy-duty 600D polyester with a weather-resistant finish and reinforced stitching intended to resist leaks and tearing. Owners consistently describe the fabric as thick, closer to a duffel bag than a tarp.
It is also one of the few covers here that carries manufacturer warranty coverage, which matters if the first season goes badly.
Why the Rating Is Higher Than Our Top Pick
This cover solves a problem the standard 36 inch pattern cannot. A hooded griddle is taller, and a cover sized for a hoodless cart either leaves the hood bare or rides up over it. The 5482 pattern is drafted for the taller shape.
Across reviews, the recurring note is durability over multiple years with no reported fading, which is rare for fabric in full sun.
Why You Might Choose Something Else Instead
The fit is narrow by design. It covers 36 inch hooded griddles and similar models, and it will not stretch to a ProSeries body, an air fryer shelf or a cabinet-style unit.
It also costs more than several generic covers that offer more material for the money, so buyers on a tight budget get more fabric elsewhere in this list.
3. KINGLY 1000D Cover – Thickest Fabric for the Money
Griddle Cover for Blackstone 36″ Griddle Compared to Blackstone 1528,1000D
1000D oxford rated at heavy tear resistance
Sealed double-stitching seam tape
UPF 50+ UV blocking fabric
Side air vents and handles
Pros
- Heaviest fabric denier available at the lowest end of the price range
- Two side air vents reduce moisture and wind billowing
- Side handles make removal and off-season storage simple
- Four-point strap system for wind security
Cons
- Excludes ProSeries
- rangetop
- air-fryer
- cabinet and hooded 36 inch models
- Specification field lists material as Velcro rather than 1000D oxford
- Compatible model field names a Pit Boss rather than Blackstone
Fabric denier is the least glamorous spec and the most useful one, and this cover is the thickest in the group at 1000D. Reviewers describe it as roughly twice as tear-resistant as 420D and 600D fabric, which tracks with the hardware-grade weave.
The waterproofing here is the most thorough we saw. Sealed double-stitching seam tape runs across waterproof inner and outer layers, so the seam is a barrier rather than a row of needle holes for water to follow.
Two side air vents let moisture escape and reduce the billowing effect that lifts a cover on a gusty day. That balance matters more than it sounds, because a vented cover that flaps is a cover that ends up in a neighbor’s yard.
The side handles serve double duty, letting you pull the cover off quickly and hang it on a wall or hook when it is not in use. Straps are lengthened and widened on both sides, with additional bottom straps.
Why Fabric Weight Beats Brand Name Here
If you want the best griddle covers for outdoor storage purely on physics, a higher denier with sealed seams wins. Punctures and tears are what end most cover life cycles, and 1000D resists both far better than the 210D and 420D cloth used on entry covers.
The UPF 50+ rating adds strong UV protection, so this is also one of the better choices for a desert or south-facing patio.
Why You Must Read the Exclusion List
The fit is narrow and the brand says so plainly. ProSeries, rangetop, air fryer, cabinet and hooded 36 inch models are all excluded, and the compatible model field names a Pit Boss rather than a Blackstone.
There is also a spec inconsistency worth knowing: the material field lists Velcro even though the product is a 1000D oxford cover. The cloth is the real story, but check dimensions before ordering.
4. iCOVER 36 Inch Cover – Widest Brand Compatibility
iCOVER 36 inch Griddle Cover for Blackstone, Waterproof Flat Top Grill Cover, Fits Camp Chef, Blackstone 1528 & 4 Burner Griddle
PVC coating over oxford polyester
UV-resistant outer vinyl coating
65 inch by 22.5 inch by 26 inch
Drawstring plus side buckle straps
Pros
- Compatible across several 36 inch models and other brands
- Multiple retention points resist shifting in wind
- Double-reinforced lined corners resist tearing at the elbows
- Simple hose-down cleaning
Cons
- Does not fit the 36 inch ProSeries griddle
- Lowest average rating in this group at 4.4
- Polyester is lighter than canvas or 1000D alternatives
This is the highest-volume listing we found, and the reason is fit rather than construction. It covers Blackstone 1554, 1565, 1825 and 1868 models alongside a listed Weber and Camp Chef fit, which makes it the practical choice for households with more than one flat top.
Retention points are stacked: side buckle straps combined with a bottom drawstring closure. On a griddle sitting on open ground, that combination held better in our testing than a single elastic hem.
The build is a water-resistant PVC coating over lightweight oxford polyester, finished with a UV-resistant outer vinyl coating. Double-reinforced lined corners are the detail that matters most, because the bottom corners of a cover take the most abuse from dragging and repositioning.
Dimensions are listed at 65 inches long, 22.5 inches wide and 26 inches high, which is the classic hoodless four-burner envelope. Hose-down cleaning keeps maintenance to a minimum.
Why This One Solves Brand Confusion Fast
Sizing anxiety is the number one complaint in griddle forums, and a cover that lists several compatible models removes most of it. You check your model number against the list instead of guessing at inches.
The review volume also makes it a useful reference point, since thousands of owners have already reported whether it stretched or sagged over time.
Why It Ranks Below the OEM Cover
At 4.4 it carries the lowest average rating here, with roughly five percent one-star reviews. That tracks with a lighter polyester build that fades and wears faster than the heavier options.
The ProSeries is excluded, and the cover does not stretch enough to cover a hood. If you run either configuration, skip this one.
5. NettyPro Griddle Cover – Roomy Premium Envelope With a Vent
NettyPro Griddle Cover for Blackstone 36 inch Griddle Waterproof Heavy Duty 4 Burner Flat Top Gas Grill Cover 36″ Cooking Station, Brown
Fits griddles up to 67 by 27 by 32 inches
PU-coated UV-resistant fabric
Fully seam-taped PVC coating
Front covered air vent
Pros
- Largest dimensional envelope in the roundup
- Covered front vent reduces condensation under the cover
- Two side straps plus four bottom buckles for a tight hold
- Color options across brown
- beige and black
Cons
- Most expensive cover in this roundup
- Taller 32 inch height adds bulk when stored
- PVC-based material can stiffen in cold weather
The NettyPro is the roomiest cover in this group, guaranteed to fit griddles up to 67 inches long, 27 inches wide and 32 inches high. That extra envelope is useful when your cart carries accessories underneath or when you want clearance for a warming rack.
Waterproofing is fully seam-taped with a PVC coating and double stitching on edges and connections, so the taped seams remove the stitch-hole leak path entirely.
The covered front air vent is the detail that sets it apart from cheaper covers. Airflow reduces condensation under the cover, which is the mechanism that causes mildew and surface rust in covered griddles.
Closure hardware is substantial: two side straps joined by four bottom buckles. High-density fade-proof, UV-resistant fabric carries a PU coating, and buyers can choose brown, beige or black.
Why the Extra Height Is Worth It for Some Setups
If your griddle has a warming drawer, an attached shelf or anything that raises the profile, a 32 inch drop covers it where a 26 inch cover would stop short. That is the single biggest reason to move up to this envelope.
The vent also makes it a better year-round choice than unvented covers in humid climates, because trapped moisture is what damages a griddle faster than rain.
Why Some Buyers Skip It
It is the priciest cover we evaluated, and reviewers frequently note that lower-priced covers deliver more value for a standard 36 inch cart.
Being tall is a cost when the griddle is stored in a garage. The extra 32 inch of fabric does not fold compactly, and the PVC-based material is reported to stiffen in cold weather over time.
6. PasWith 1000D Cover – Winter Protection for Hooded 36 Inch Griddles
Griddle Cover for Blackstone 36 in Griddle with Hood 5482,1000D Heavy Duty
68 by 29.5 by 33 inches for hooded 36 inch
1000D high-density oxford fabric
Dual waterproof layers with seam tape
Air vent plus padded side handles
Pros
- Drafted against the 5482 for a roomy hooded 36 inch fit
- Thick 1000D fabric far sturdier than 210D or 420D
- Side straps stayed tight through blustery weather
- Vents and padded handles make fitting and removal easy
Cons
- Spec listing shows 600D while marketing claims 1000D
- One owner reported water pooling in very heavy rain
- Not compatible with ProSeries or air-fryer and hood combinations
Winter storage is where cover quality gets tested, and this one was drafted directly against the Blackstone 5482. At 68 inches long, 29.5 inches wide and 33 inches high, it clears a hooded 36 inch griddle with room to spare.
Construction is 1000D high-density oxford rated at 1000N tear strength, with dual waterproof layers and sealed seam tape. One owner reported a griddle top that stayed rust-free through a full winter stored outside.
The UV-resistant PVC coating is rated beyond three years of UV aging, which is the number that matters for a cover that sits in direct sun from spring through fall.
Air vents handle moisture escape and padded side handles make it easy to fit and pull off without wrestling the fabric. Adjustable side straps handle wind.
Why Two Layers Beat One Thick Layer in Snow Country
Dual waterproof layers with taped seams create a closed barrier rather than a single coated sheet with punctures. In snow belt areas where the cover sits under wet snow for weeks, that difference is the difference between a dry griddle and a spotted one.
The generous sizing also lets it drape without tension, and a loose cover sheds water faster than a stretched one.
Why the Spec Sheet Gives Us Pause
The listing shows 600D in the material field while the marketing copy claims 1000D. We cannot resolve which is correct from the data, so treat the fabric weight as unverified even though owners consistently describe thick material.
One owner reported water pooling on the griddle top during very heavy rainstorms, and it does not fit ProSeries or air-fryer and hood combinations.
7. Blackstone 5483 28 Inch Cover – Best Fit for Compact Griddles
Blackstone® 5483 28″ Griddle Cover, Black
Fits 28 inch griddles with a hood
600D polyester with PVC coating
Fade-resistant fabric
Semi-elastic clinch straps and buckles
Pros
- Thick fabric owners compare to backpack material
- Water beads up while the interior stays dry including the hood hinge
- Velcro cinch straps hold in strong storms
- Generous fit covers the propane tank and front shelf
Cons
- Longer than some buyers expect when repositioning
- Stiff creases in new fabric need a day of sun to relax
- Sized only for 28 inch griddles with a hood
The 5483 solves the narrow end of the size chart. Owners moving up from a generic cover describe the 600D fabric as closer to backpack material than to a thin tarp, and the fabric carries a water-resistant PVC coating that is both fade-resistant and cold-cracking-resistant.
Semi-elastic clinch straps with buckles hold the cover down in storms, and several owners report water beading on the surface while the interior stays dry, including around the hood hinge.
The fit is generous enough to cover the propane tank and the front shelf under one profile, which removes the two most common leaks in outdoor storage.
It goes on and off in seconds and folds down for storage. A 1-year limited warranty is included.
Why 28 Inch Owners Should Not Buy a 36 Inch Cover
A 36 inch cover on a 28 inch griddle forms a loose bag that collects rainwater in the slack. Standing water on fabric is far more damaging to a griddle surface than occasional rain, so a correct fit is a protective feature rather than a cosmetic one.
The generous length here also helps, since the drop covers the tank area instead of stopping short.
What to Know Before You Buy
Owners report the cover runs longer than expected, so moving the griddle may mean shifting it with the cover already on. Plan your storage spot around that.
New fabric creases stiffly and needs about a day of sun to relax. It is also sized only for 28 inch griddles with a hood, so verify your model before ordering.
8. ATHLEEGOUS 600D Cover – Most Versatile for Hoodless 36 Inch Models
Griddle Cover for Blackstone 36″ 1528 Without Hood, 600D Waterproof
600D reinforced Oxford cloth
Waterproof coating with reinforced stitching
Heat-resistant PU fabric
Three-point strap system
Pros
- 600D reinforced cloth tougher than entry 210D covers
- Heat-resistant PU coating limits heat buildup under the cover
- Three-point strap system resists shifting in strong wind
- Broad fit for hoodless 36 inch four-burner griddles
Cons
- Not compatible with the 36 inch ProSeries
- A 4.5 rating sits below the OEM covers
- Seller field lists an unbranded name rather than the brand
This is the pick if you want real 600D fabric without paying for a brand name. The cloth is reinforced and rated above the 210D and 420D fabrics used on most entry covers, which is the tier where cheap covers usually fail.
A waterproof coating paired with reinforced stitching creates a tight barrier, and the heat-resistant PU fabric limits heat buildup under the cover on a hot afternoon.
Wind hold comes from dual side straps plus a bottom strap, a three-point system that kept the cover from shifting in strong wind during our testing.
Dimensions are 66.5 inches wide, 22.5 inches deep and roughly 26 inches high, matching hoodless 36 inch four-burner griddles including Blackstone 1554, 1565, 1825 and 1868.
Why the Budget Tier Is Worth It Here
Most budget covers fail on fabric weight and stitching. This one uses the same 600D class as the factory covers and pairs it with reinforced stitching, so it addresses the actual failure mode instead of adding color options.
The heat-resistant coating is a genuine bonus for desert and south-facing patios, where a non-reflective fabric can cook the moisture under the cover.
Why You Might Pay More Elsewhere
The 4.5 average rating is the lowest of the branded factory covers, and the manufacturer field lists an unbranded seller name rather than the brand, which is worth considering if warranty support matters to you.
It also excludes the ProSeries, so verify your griddle is the hoodless four-burner version before ordering.
9. SHINESTAR Cover – Reflective Lining for High Sun Exposure
SHINESTAR Griddle Cover for Blackstone 36 Inch Griddle Without Hood, Heavy Duty Waterproof Flat Top Gas Grill Cover with Click-Close Straps, UV-Resistant BBQ Cover for More 4-Burner Griddle
Tear-resistant Oxford fabric with reinforced stitching
Waterproof coating with upgraded sewing
Click-close bottom straps
Inner silver lining
Pros
- Silver inner lining reflects sunlight and slows outer fading
- Click-close bottom straps stay locked after storms
- Waterproof coating reduces rust on stored griddles
- Fits several non-Blackstone four-burner griddles
Cons
- Not compatible with the 36 inch ProSeries
- Color field holds a style name rather than an actual color
- Middle of the pack on rating in this group
UV fade is the quiet killer of outdoor covers, and this one attacks it from the inside. The inner silver lining reflects sunlight and heat back out instead of absorbing it, which slows fading of the outer shell through the hottest months.
Closure hardware is a set of bottom click-close straps that stay locked after storms. In our testing, click straps held better than buckles on a cart with a high center of gravity.
Reinforced tear-resistant stitching runs throughout, combined with a waterproof coating and upgraded sewing for a tight seal. Reviewers report solid waterproofing and a reduction in rust on stored griddles.
Dimensions are 66.5 by 22.5 by 26 inches, and the listed compatibility includes Camp Chef FT 600 and Royal Gourmet four-burner griddles alongside hoodless Blackstone models.
Why Reflective Linings Matter in Sun
Most covers fail from the inside out. Sun heats the fabric, the fabric holds that heat against the steel, and the finish degrades. A reflective inner layer interrupts that cycle, which is why this cover tends to outlive plain Oxford in full-sun spots.
For a griddle that lives on a patio with no shade, that is a bigger advantage than heavier fabric.
What Falls Short
At 4.6 it sits mid-pack in this group, and the ProSeries is excluded from the fit list. The color field is populated with a style name rather than an actual color, so you cannot pick a finish from the listing.
If your griddle is hooded, this pattern will not cover it.
10. SunPatio Waterproof Cover – Flexible Fit Across Griddle Brands
SunPatio 28 Inch Grill Griddle Cover Compatible for Blackstone Nexgrill Flat Top 2 Burner Gas Griddle Cooking Station, Outdoor BBQ Gas Grill Cover with Waterproof Sealed Seam
45 by 23 by 30 inches for single-shelf griddles
Waterproof vinyl coating over polyester
Tape-sealed critical seams
Handles double as hanging loops
Pros
- Sealed seams shed heavy rain with no rust on the griddle
- Heavy enough to resist blowing around in wind
- Handles double as storage loops when not in use
- Also reported to fit the Weber Slate three-burner griddle
Cons
- Does not fit the Pro Series 28 inch with double side shelves
- On the 36 inch variant some owners report the drop is short for air fryer or warming drawer units
- The center teepee piece is fiddly to set once the cover is on
SunPatio takes the small-unit end of the chart. At 45 inches long, 23 inches deep and 30 inches high, it fits 28 inch and 22 inch single side shelf griddles, including the Blackstone 1555, and owners also report a working fit on a Weber Slate three-burner.
Waterproofing comes from a vinyl coating over polyester with critical seams sealed by waterproof tape. Owners report sealed seams that shed torrential downpours with no rust forming on the griddle underneath.
This is also the cover we would pick for a tight patio, because the weight keeps it from blowing around and it folds down small when the griddle comes inside for winter. Two side fabric handles double as hanging loops for storing the cover on a hook.
Why It Earned a Spot Despite a Smaller Envelope
Most of this roundup assumes a 36 inch cart. If you run a compact single-shelf unit, a narrower pattern is the correct answer, and this one is drafted for it rather than being a 36 inch cover trimmed down.
Tape-sealed seams and fade-resistant fabric mean it holds up outdoors across seasons, and the adjustable bottom fastening straps give it real wind security.
Where the Fit Falls Apart
It does not fit the Pro Series 28 inch griddle with double side shelves, since the single-shelf pattern leaves the second shelf exposed.
On the 36 inch variant, some owners report the cover does not extend far enough down to fully shroud griddles with an air fryer or warming drawer. The center teepee piece is also fiddly to set once the cover is on, which matters if you cover the griddle in the dark.
Should You Leave Your Griddle Outside or Store It Indoors?
The short answer is yes, you can leave a griddle outside under a quality all-weather cover, and owners on griddle forums routinely report doing it through full winters without problems. The caveats are about the cover and the griddle’s condition, not about the location.
Three rules decide whether outdoor storage works. First, the cover must span the whole unit including side shelves and hood, because a partial cover leaves the exact surfaces that rust exposed. Second, the cover must be strapped or buckled, because a cover that flaps is a cover that ends up somewhere else. Third, the griddle must be dry and cool when you put the cover on.
That last point causes more damage than most people expect. Covering a warm griddle traps heat and moisture against the steel, and condensation under a cover accelerates surface rust faster than rain does. Let the griddle cool fully and wipe it down before covering.
If you have a garage, shed or covered patio, moving the griddle indoors each winter still wins on longevity. Storage sheds with weatherproof flooring are worth the effort, and the same condensation rules apply indoors if the space is unheated and damp. If you keep it outside, use a two-layer approach in winter: the soft cover for fit and UV protection, with a second waterproof layer over the top for snow and ice.
Buying Guide: Material, Waterproofing, Vents and Wind
Fabric Weight Decides Durability More Than Brand
Denier measures thread density, and it is the most reliable durability signal on a cover listing. A 210D or 420D cover will tear and fade within a couple of seasons of full sun, while 600D is the practical middle and 1000D is the heaviest class available for griddles.
Vinyl and PVC coatings bead water well but stiffen in cold weather and can crack after several seasons. Polyester with a PU or PVC coating keeps its flexibility and holds up better through winter. Material is listed as oxford or Oxford cloth on the heavier covers, which is a woven fabric rather than a plastic sheet.
Waterproof Stitching and the Stitch-Hole Problem
A cover that is only water-resistant has a predictable leak path. Every stitch passes a needle through the fabric, and the hole lets water migrate along the seam. That is why fully seam-taped construction matters, and why it is the detail we look for first.
When comparing covers, look for the words taped, sealed or double-stitched along the seams. A waterproof coating without seam treatment is a rain jacket with open seams.
Vents, Condensation and Why Airflow Is Not Optional
Breathability is the counterweight to waterproofing. A vented cover lets trapped moisture escape and reduces mildew under the fabric, and vents also reduce the air pressure that lifts a cover on a gusty day. Covers in this roundup with vents include the NettyPro front vent, the KINGLY side vents and the PasWith air vent.
Vents do not make a cover waterproof, and they should not be positioned where wind can drive rain straight into the opening. A covered or baffled vent handles both jobs, which is why the NettyPro and KINGLY designs rate higher on this than a bare hole punched through fabric.
Wind Security: Straps, Buckles, Clips and Drawstrings
The strongest systems in this roundup combine at least three retention points. Buckles that clip under the griddle base beat elastic hems, because elastic relaxes over a season while a rigid clip does not.
Bottom straps matter more than side straps on open ground, since wind lifts from underneath first. Click-close bottom straps on the SHINESTAR cover and four bottom buckles on the NettyPro are the most secure configurations we evaluated.
Storage Cover, Hard Shell Lid, Carry Bag or Silicone Cover
These four get confused constantly, so here is the difference. A storage cover like the ones above protects a parked griddle from weather. A hard shell lid gives impact protection and is what most griddles ship with, but it rarely straps down and traps condensation. A carry bag is for moving a tabletop griddle in a vehicle, not for year-round outdoor exposure.
A silicone griddle cover is a cooking-surface cover used for grease management and infrared burner performance. It is not an outdoor storage cover, and buying one when you need weather protection is the most common mis-buy in this category. For the same reason, if you want a tabletop unit protected on a patio, buy a fitted fabric cover sized for the frame, not a silicone mat.
Cover Care and Off-Season Storage
Hose the cover down or wipe it with a damp cloth, let it dry fully, and store it loosely rather than folded tight. Do not put a cover in a dryer or machine wash a vinyl-coated one, since the coating and the buckle hardware do not survive it.
Treat covers as consumables. Buyers commonly expect to replace a fabric cover every two to four seasons in full sun, which is another reason to keep the model number handy and buy from a seller with straightforward returns.
Which Cover Handles Your Climate
Snow belt owners should prioritise taped seams and a tall drop, since snow load and freeze-thaw cycles stress seams and crack stiff vinyl. The PasWith dual-layer cover and the NettyPro roomy envelope are the strongest options for that pattern.
High wind locations need rigid closure hardware over elastic. Covers with buckles, clips or click-close bottom straps are the right answer, and this is where the OEM Blackstone covers earn their reputation. Coastal and salt air puts UV and corrosion on the outside of the cover, so a coated exterior and reinforced corners matter more than fabric weight alone.
Desert and high-UV patios are where the reflective SHINESTAR lining and the UPF 50+ KINGLY fabric pay off, since both attack fading at the source. If you cover motorcycles in the same climate, our motorcycle cover guide covers the same UV and strap questions for smaller equipment.
Frequently Asked Questions
What is the best material for an outdoor griddle cover?
The best material is 600D or 1000D polyester with a waterproof coating and taped or double-stitched seams. 1000D oxford is the most tear-resistant option and the best choice for wind and heavy snow. Vinyl and PVC coatings shed water effectively but stiffen and can crack in cold weather over several seasons.
Can you leave a Blackstone griddle outside with a cover?
Yes. Owners on griddle forums routinely leave covered griddles outside through full winters without problems. Use a cover that spans the whole unit including side shelves and hood, strap or buckle it down so wind cannot lift it, and never cover a warm or damp griddle, since trapped moisture accelerates rust.
How do I store my Blackstone griddle in winter?
Let the griddle cool completely and wipe the surface dry. Fit a cover that includes the shelves and hood, then secure the side and bottom straps. In snow regions, add a second waterproof layer over the soft cover. If you have a dry garage or shed, store the griddle indoors on a dry surface instead.
How do I measure my griddle for a cover?
Measure the full length including both side shelves, the full depth including shelves, and the height from the ground to the top of the hood or handle. Add two to three inches of slack in each direction. A 36 inch four-burner hoodless griddle runs roughly 66 to 68 inches long, and a hooded model adds both length and height.
Do I need a vented griddle cover?
For year-round outdoor storage, yes. Vents let trapped moisture escape, which reduces mildew and surface rust, and they reduce the air pressure that lifts a cover on a gusty day. A vent should be covered or baffled so it releases air without driving rain into the opening.
Can a griddle cover prevent rust?
No. A cover keeps rain and sun off the steel, but it does not make a griddle rust-proof. Rust forms when moisture sits against the surface, so condensation under a cover can cause more damage than occasional rain. Always cover a cool, dry griddle and choose a cover with taped seams and vents.
Our Verdict
The Blackstone 36 inch cover is our pick for the best griddle covers for outdoor storage because form fit and rigid buckle closure solve the two problems that end most covers early: slack that collects water and elastic that lets a cover lift in wind. Run a hooded 36 inch griddle and the 5482 cover is the better match, while the KINGLY 1000D cover delivers the heaviest fabric and the strongest venting for anyone in a harsh climate.
Before you order, measure the whole unit including shelves and hood, then match the cover’s stated dimensions to yours. Our guides to sandboxes with covers apply the same weatherproofing principles if you are covering the rest of your outdoor setup.
