Blue Wave solar blanket for oval pools – 18×33 ft Blue, 8‑mil UV‑resistant cover that reduces evaporation

Blue Wave's 8-mil oval solar blanket for 18×33-ft above-ground pools is a lightweight blue cover that traps solar heat, reduces evaporation, and blocks debris while resting on the water surface.

Designed for pool owners who want warmer water without adding heaters, this Blue Wave solar cover uses thousands of air-filled thermal bubbles to collect sunlight and slow overnight cooling. Sized for 18 ft × 33 ft oval above-ground pools, the 8-mil material balances toughness with easy handling so you can place and remove it without heavy equipment. The blanket is UV-protected for extended outdoor use and can be trimmed with household scissors to fit around ladders and accessories.

How does this solar blanket warm my pool?

The cover floats directly on the water so sunlight passes through the blue sheet and the bubble layer traps and transfers heat into the water. Its thermal air pockets capture energy during daylight and insulate against heat loss at night, producing more consistent swim temperatures over the season.

• Thousands of air-filled thermal bubbles capture and hold solar energy.
• Blue translucent material lets sunlight through for efficient heating.
• Insulating effect reduces radiant and convective heat loss after sunset.
• Can raise water temperature by up to 15°F on sunny days under optimal conditions.

Will the cover cut down on water loss and debris?

Yes—the blanket acts as a surface barrier that dramatically slows evaporation and keeps leaves and dirt out of the pool between uses. Less evaporation means lower chemical consumption and fewer top-offs, while fewer contaminants reduce filtration and skimming time.

• Prevents up to 95% of pool water and chemical evaporation in typical use.
• Surface barrier blocks leaves, pollen and dirt from entering the water.
• Reduces time spent on routine cleaning and chemical adjustments.

How easy is it to use, store and fit around pool accessories?

The 8-mil thickness was chosen to provide reliable durability while remaining light enough for one or two people to handle. The cover can be trimmed with household scissors for a custom fit around ladders or returns, and simple rolling (not folding) makes seasonal storage easier and helps preserve material life.

• Lightweight 8-mil film for easy placement and removal.
• Trim-to-fit design lets you cut around ladders and fittings.
• Recommended storage: dry, shaded area; roll instead of fold to avoid creases.

What should I know about durability and warranty?

Blue Wave builds this cover with UV-resistant additives to extend outdoor life, balancing cost and performance for everyday seasonal use. While no cover is indestructible, proper handling—keeping it out of direct sunlight when stored, rolling it, and ensuring the surface is free of sharp objects—helps maximize its lifespan.

• UV-protected film formulated for prolonged outdoor exposure.
• 8-mil thickness offers a practical mix of toughness and manageability.
• Includes Blue Wave's 3-year limited manufacturer warranty.
