The cover you put on in fall decides what you find when you pull it off in spring: clear water or a green, leaf-filled mess. If you’re comparing options before closing day, this guide explains how to pick the best winter cover for an above ground pool. It covers what each cover type actually does, how Midwest snow changes the decision, and the accessories that make any cover work better.
Winter Cover vs. Safety Cover: What’s the Difference?
These two names get used interchangeably, but they do different jobs.
A winter cover protects your water. It keeps out leaves, dirt, and sunlight while the pool sits closed, which limits algae growth and makes spring opening much easier. On an above ground pool, a winter cover usually floats on the water and is held in place around the top rail.
A safety cover protects people. Safety covers are tensioned tightly across the pool and anchored to keep a child or pet from falling into the water. They’re most common on in-ground pools, where they anchor into the surrounding deck. If you’re buying one, look for a cover that meets ASTM F1346, the industry standard for safety covers.
One point matters for every pool owner: a standard winter cover is not built to hold a person’s weight. It keeps debris out, but it isn’t a barrier. Federal Pool Safely guidance notes that a proper safety cover can stop children from getting into the water when no adult is around, and it treats covers as one layer of protection alongside fencing, alarms, and supervision. The CPSC’s barrier checklist for pool owners is a good review before you close for the season. poolsafely
For most above ground owners, the practical setup is a quality winter cover plus the safety features the pool already has. That means a secure fence, a ladder that’s raised or removed, and a gate that stays latched.
Solid vs. Mesh: Choosing the Best Winter Cover for an Above Ground Pool
Once you know you need a winter cover, the main decision is the material.
Solid covers block water, debris, and sunlight completely. With no sunlight reaching the water, algae has a much harder time growing, so you open to clearer water in spring. The trade-off is that rain and melting snow collect on top, and you’ll need to remove that water during the winter.
Mesh covers let rain and snowmelt drain through while catching leaves and larger debris. They’re lighter and require less work in winter, but fine dirt and sunlight get through. Expect more cleaning and water balancing at opening.

For most Midwest above ground pools, a solid winter cover is the better choice. Our winters are long, and a cover that keeps the water clean from October to April saves a lot of spring cleanup. You just need to manage the water and snow that build up on top.
How Midwest Snow Changes the Equation
Snow is the part of the decision that national buying guides tend to skip.
Snow weighs more than most people think, and the weight varies widely. University of Minnesota Extension notes that snow density ranges from about 3 pounds per cubic foot for light, fluffy snow to 21 pounds per cubic foot for wet, heavy snow, and ice weighs roughly 57 pounds per cubic foot. A late-season storm that turns to rain, then freezes, can put a lot of weight on your cover.
That weight doesn’t hurt a well-made cover by itself. Problems start when standing water, slush, and ice sit on a cover for weeks. That stretches the material, strains the seams and attachment points, and pulls on the edges. A few habits prevent most of it:
- Keep standing water off a solid cover. A cover pump makes this quick.
- Don’t let heavy, wet snow pile up for long stretches. You don’t need to clear every flurry. But after a big wet storm, take some weight off if you can do it safely from the ground.
- Never walk on the cover or use sharp tools on it. Use a soft roof rake or a broom, never a shovel.
The Accessories That Make Any Cover Work
A good cover performs best with a few inexpensive extras:
- Air pillow. This inflatable pillow sits under the center of the cover. It creates a gentle crown so water and snow slide toward the edges, and it gives ice room to expand in the middle instead of pushing outward on the pool walls.
- Cover pump. A small submersible pump clears rain and snowmelt from a solid cover without lifting it.
- Water bags or wall bags. These help hold the cover snug against the pool and keep wind from getting underneath.
- A secure attachment system. Many standard above ground covers use a cable and winch around the top rail. A cover designed for your specific pool will usually fit tighter and resist wind better than a generic one.
That last point is where fit matters. Kayak’s above ground winter pool cover is designed specifically for Kayak Pools, with heavy-duty tarp tabs every four feet that line up with the pool’s posts and heavy-duty water bag loops at the same spacing. The cover is reinforced, non-corrosive, and non-abrasive. Round models include a three-foot overlap, and warranties range from six to twelve years depending on the model. kayakpoolsmidwestkayakpoolsmidwest
Quick Guide: Which Cover Fits You?
- You want clear water at opening and don’t mind occasional pumping: a solid winter cover with an air pillow.
- You want the least winter upkeep and accept more spring cleaning: a mesh winter cover.
- You have heavy tree cover nearby: a solid winter cover, plus a leaf net in fall until the trees are bare.
- Your top concern is keeping kids or pets out of the water: a cover rated to the safety standard, combined with fencing, a raised ladder, and a latched gate. A winter cover alone doesn’t do this job.
Getting Your Cover On Right
Even the best cover works only if it’s installed well. Clean and balance the water before closing so you aren’t sealing in debris. Position the air pillow in the center before you lay the cover over it. Pull the cover evenly so it overlaps the top rail all the way around. Make sure the cover is the right side up: Kayak’s winter cover goes on with the black side facing down and the blue side facing up. Then check it after the first big storm and adjust anything the wind has loosened. kayakpoolsmidwest
