Every fall, you face the same choice: throw a thin tarp over your above-ground pool and hope it survives winter, or buy a cover that actually keeps leaves, snow, and ice out so spring opening is a quick cleanup instead of a swampy nightmare. A cover with a weak weave rips at the first ice storm, leaving you with a full pool of frozen debris. One with the right scrim count (threads per square inch) and material weight handles snow loads and wind gusts for multiple seasons. This guide compares five top options for 18-ft rounds to 18 x 33-ft ovals, using real specs like scrim count and material density so you know exactly which cover matches your local weather.

The moment you close your pool, the right cover decides whether spring brings clear water or a mess of algae and torn fabric. The best above ground pool covers balance thickness, weave density, and installation ease to keep your pool clean and protected through every season.
How To Choose The Best Above Ground Pool Covers
Picking the wrong above ground pool cover means spending spring with a pump and a headache. Focus on these three things to get it right the first time.
Scrim Count: The Number That Predicts Lifespan
Scrim is the number of threads woven into each square inch of the cover material. A higher scrim count — 14×14 means 14 threads per inch in each direction — gives you a denser, stronger weave that resists tearing when snow piles up or wind whips across the yard. An 8×8 scrim is standard for light-duty covers and may last two seasons, while a 14×14 scrim can handle multiple winters without ripping at the grommets.
Mil Thickness: Solar Blankets vs. Winter Covers
Mil (one-thousandth of an inch) measures the material’s thickness. For solar bubble blankets that heat your pool, 8-mil to 16-mil is the typical range — thicker bubbles hold heat better overnight but are heavier to handle. Winter covers, however, rely more on scrim count and overall material weight (measured in grams per square meter or ounces per square yard) than on mil thickness alone. A heavy winter cover at 185 gsm will outlast a thin tarp regardless of the mil number.
Installation System: Winch vs. Cable vs. Water Weights
Your cover is only as good as how well it stays on. Winch-and-cable systems let you ratchet the cover tight around the pool walls, which is critical in windy areas. Some covers include a steel-core cable with a molded winch that one person can operate. If your pool has a deck, you may need water weights placed on top of the cover instead — check the product details for deck compatibility before buying.

In-Depth Reviews
1. Planenfux 24 Ft Round Pool Cover
24 ft round, 200 gsm polyethylene with a 14×14 ripstop weave — this is the top pick for anyone who wants one cover to handle both winter and summer, eliminating the need to buy and store a second product.
Buyers report this is the best cover they have owned in 19 years, citing thick material and well-placed rustproof grommets that make the winch-and-cable system easy to tighten. The patented SmartSide Technology means you flip the black side up in summer for solar heat gain (testing shows up to +10°F) and flip the blue side up in winter to reflect UV — and the cover is performance-tested from -40°F to 160°F, so it handles everything from a blizzard to a July heatwave without cracking.
The downside is that this is a heavy cover — at 24 pounds (10.91 kg), it is 60% heavier than the Robelle winter cover — so one-person installation requires some muscle, though owners mention the weight also makes it less flimsy to position. For anyone who wants a single cover that works year-round and outlasts cheap alternatives by 3-5 seasons, this is the one to beat.
Why it’s great
- 14×14 ripstop scrim — the densest weave in this roundup, tested to -40°F
- 2-in-1 winter cover plus solar heat boost replaces two separate products
- Winch and steel-core cable included, stays tight through 60+ mph gusts
Good to know
- Heavy at 24 pounds; easier with two people for initial placement
- Edge reinforcement is durable, but the weight can make folding for storage a chore
2. Yankee Pool Cover for Oval Pool 18 x 33-ft
Against the top pick’s 200 gsm material, the Yankee Pool Cover for Oval Pool 18 x 33-ft uses 185 gsm — a 15 gsm difference — while both share a 14×14 scrim count. This still makes it roughly 2.3 times denser than the 2.36 oz/yd² (about 80 gsm) Robelle cover, and its tested temperature range of -10°F to 180°F covers deeper freezes and hotter sun than the competition.
Buyers with 23+ years of pool ownership report zero edge wear after a harsh New Jersey winter with heavy snow and strong winds. The LDPE coating resists UV degradation, and the black underside blocks sunlight to prevent algae overgrowth. The steel-core cable and molded winch let you ratchet the cover tight without tools, and reviewers confirm it stays put through Connecticut ice storms with no rips or tears.
This is a dedicated winter cover, not a solar blanket — you get unmatched cold-weather toughness but no summer heating benefit. Choose this over the top pick if your priority is surviving brutal winters with a cover that lasts five-plus years, rather than maximizing material density by a small margin.
Where it shines
- 14×14 scrim plus 185 gsm density — nearly 2.3x the material weight of standard 8×8 covers
- Tested to -10°F and 180°F, handles both deep freezes and intense summer UV
- Customers note zero edge wear after full harsh-winter seasons
Worth noting
- Winter-only use; no solar heating feature for warmer months
- Pool pillow sold separately, so budget extra if you need an ice equalizer
3. VEVOR Solar Pool Cover, 18 ft Round, 16 Mil
Your main goal is keeping your pool warm enough to swim comfortably in the evening without running the heater all night — the VEVOR solar blanket delivers on that promise. Its 16-mil bubble design is exactly twice the thickness of the Blue Wave 8-mil solar cover, and that extra thickness translates directly into better overnight heat retention. One buyer specifically reports that their pool retains its temperature within 2-4 degrees overnight until the heater kicks on in the morning, which is about as direct a proof point as you can get.
The micro-bubble surface captures solar heat during the day and the PE (polyethylene) material reduces heat loss at night, which means less reliance on your electric heater and lower energy bills. At 18.96 pounds, it is 26% heavier than the Robelle winter cover, but that extra heft comes from the dense bubble layer — and reviewers point out the material feels thick and quality-made, with welded seams that are square-cut for easy installation on a roller system. It also reduces water evaporation by up to 95%, so you refill the pool less often and lose fewer chemicals to the air.
A few shoppers say that the black bottom of the bubbles may block some sunlight from reaching the water, which is a physics trade-off of thicker insulation — you get better heat retention but slightly slower daytime warming compared to thinner, more transparent covers. Still, at 16 mil with a five-star average from verified reviews, this is the solar blanket to pick if overnight temperature drop is your biggest frustration.
What stands out
- 16 mil thickness — 2x thicker than standard 8-mil solar blankets for better overnight insulation
- Buyers confirm 2-4°F overnight temperature retention until morning heater
- Reduces water evaporation by 95%, saving on refills and chemical top-ups
The trade-offs
- Black bubble bottom may slightly reduce daytime solar absorption compared to clearer covers
- At nearly 19 pounds, handling for a single person can be awkward during installation
4. Robelle 18 x 33 ft Heavy Duty Green Winter Oval Pool Cover
The single number that matters most in this category is the scrim count, and the Robelle scores an 8×8 — a moderate weave that is 18% heavier than the industry standard, according to the manufacturer, but still sits well below the 14×14 scrim of the Planenfux and Yankee covers. Where this cover makes its case is in installation ease: the 4-foot overlap (22 x 37 ft cover for an 18 x 33 ft pool) means you have generous extra material to work with, and the included winch-and-cable system lets one person tighten it down in minutes. One buyer reports it withstood 60+ mph winds using the ratchet device, which is impressive for a cover at this level.
At 15 pounds, it is the lightest full-size winter cover in this roundup — 60% lighter than the Planenfux — which makes it far easier to drag across the pool alone. The polyethylene material (2.36 oz per square yard / 80 gsm) is thinner than the premium covers, but buyers in temperate zones report getting 2-3 seasons out of it, and some expect 5+ years with normal wear. Robelle backs it with a 10-year warranty, which is the longest warranty on this list and suggests confidence in the product despite the moderate scrim count.
The trade-off is straightforward: you get a lighter, easier-to-handle cover that costs less, but the 8×8 scrim means it will not survive heavy snow loads or repeated ice storms as well as the 14×14 options. For temperate zones with mild winters or for budget-minded buyers who plan to replace the cover every few years, the Robelle offers the best price-to-value read in this roundup.
The upsides
- 4-foot overlap makes installation forgiving and easy for one person
- 10-year warranty — longest warranty of any cover on this list
- Only 15 pounds, much lighter than premium 14×14 covers for easier handling
Keep in mind
- 8×8 scrim is less dense than 14×14 covers; expect 2-3 seasons rather than 5+ in harsh winters
- Some buyers report the material is thinner than expected despite meeting specs
5. Blue Wave 24-ft Round Solar Pool Cover, 8-Mil
What you actually get at this lower price is a functional solar blanket at half the thickness of the VEVOR 16-mil cover, which means the Blue Wave warms the top layer of water effectively during full sun but loses heat faster overnight. This entry-level cover does not require anchors or tie-downs — owners mention it stays put even in heavy wind without being secured — and it trims easily with scissors to fit around ladders and odd-shaped pools.
The honest trade-off is long-term seam durability. One buyer who owned the previous version says the 2023 iteration performed well for three seasons, but the newer version feels thinner and lighter despite the same 8-mil spec, and another reviewer reports a seam started pulling apart after the second season. The 8-mil material is light at 18 pounds for a 24-ft round, making it the easiest solar blanket to roll up and store, but that lightness comes at the cost of tear resistance over time.
The Blue Wave is perfect for the budget-conscious pool owner who wants to extend the swim season by a few weeks without investing in a thicker, pricier solar blanket. Pair it with a solid winter cover for cold months, and expect to replace the solar blanket every 2-3 seasons — at this price point, that trade-off is entirely reasonable.
Why we’d pick it
- Lightweight 8-mil material is easy to cut, roll, and store by one person
- Stays in place without anchors even in heavy wind, per multiple buyer reports
- Raises water temperature effectively during sunny days for extended swim time
A few caveats
- Some recent batches feel thinner than previous versions — seam durability drops after 2 seasons
- 8-mil thickness loses heat faster overnight than 16-mil blankets; expect 2-4°F drop
Understanding the Specs
Scrim Count (Threads Per Square Inch)
Scrim is the woven mesh inside the polyethylene material that gives the cover its tear strength. A 14×14 scrim means 14 threads run each direction per square inch, creating a dense grid that resists punctures from ice, branches, and high winds. An 8×8 scrim has about a third fewer threads, making it lighter and cheaper but more likely to tear under heavy snow loads. If your winters bring more than a few inches of snow or frequent windstorms, a 14×14 scrim cover like the Planenfux or Yankee will last several seasons longer than an 8×8 option.
Mil Thickness in Solar Blankets
Mil (one-thousandth of an inch) measures the height of the air bubbles in a solar blanket. An 8-mil blanket has smaller bubbles that heat water quickly in direct sun but let heat escape faster after sunset. A 16-mil blanket has taller air pockets that act as better insulation, holding warmth through the night so your pool is still swimmable the next morning. One limitation is weight and handling: 8-mil blankets are lighter and easier to roll up, while 16-mil blankets are heavier but deliver noticeably better overnight temperature retention — typically 2-4°F warmer by morning.
