Buffalo Blizzard Supreme 18 ft x 40 ft Rectangular Winter Pool Cover

In this review the Buffalo Blizzard Supreme 18 ft x 40 ft rectangular winter pool cover is evaluated for homeowners who need a durable, easy-to-install shield for an inground pool. The bottom line: this cover excels at keeping out snow, ice, and seasonal debris thanks to a strong 10x10 Hold-tite scrim and triple-laminated polyethylene construction, making it a practical choice for colder climates where preserving liner condition and water clarity are priorities.

Key Features

• Durable Winter Protection: The 10x10 Hold-tite scrim count and heavy material resist tears and cold-weather cracking so the cover stays intact through freezing conditions.
• UV & Fade Resistant: UV-resistant nylon thread and triple-thick hems reduce sun damage and help maintain the pool liner's appearance by limiting sunlight exposure.
• Tailored Fit: The extra 5 ft of material provides full overlap beyond the pool edge to limit wind uplift and improve overall coverage.
• Secure Installation: Heavy-duty water bag loops every 4 ft and evenly spaced grommets keep the cover anchored and allow for additional fastening when needed.
• Built to Defend: Triple-laminated polyethylene construction is engineered to withstand high winds and extended sun exposure for season-to-season protection.

Who It's For

The Buffalo Blizzard Supreme is best for owners of rectangular inground pools who need a straightforward winter cover that prioritizes debris and sunlight protection. It fits well for users seeking a relatively simple installation with water bags and grommet options rather than complex anchoring systems.

Those who should look elsewhere include buyers seeking the thickest industrial-grade material available or a cover guaranteed to last many years without any reported edge wear; some customers reported mixed durability and felt the material was thinner than expected, so shoppers wanting maximum longevity may prefer a heavier commercial option.

Pros & Cons

Pros

• Good coverage and fit due to the extra 5 ft overlap that helps prevent wind from getting underneath.
• Strong scrim count and triple-laminated polyethylene deliver reliable resistance to tears and cold-weather cracking.
• Well thought out attachment points with water bag loops every 4 ft and grommets for added security during winter.
• UV-resistant stitching and hems help protect liner appearance and reduce sunlight-related fading.

Cons

• Some users report the material feels thinner than expected and durability has been mixed in real-world use.
• A few customers experienced premature wear at edges in heavy conditions, so heavy-duty commercial buyers may prefer thicker alternatives.
