Buffalo Blizzard Split Blocker 18 ft x 36 ft Rectangular Winter Pool

In this review the Buffalo Blizzard Split Blocker 18 ft x 36 ft rectangular winter pool cover is examined for homeowners who need a heavy-duty, straightforward winter barrier for inground pools. The bottom line: this cover is worth considering if you want a durable, UV-resistant shield that keeps leaves, snow and wind-borne debris out of the water and overlaps the pool edge for added security. Reviewers praised the fit and wind resistance, while a minority noted water can pool or seep through in some conditions.

Key Features

• Durable Winter Protection: The 12x12 Hold-tite scrim count and triple-laminated polyethylene construction resist tears and cold-weather cracking so the cover lasts through harsh winters.
• UV & Fade Resistant: UV-resistant materials and nylon thread reduce sunlight exposure to pool water, helping preserve clarity and protect the liner's appearance.
• Reinforced Hems: Double-stitched, triple-thick hems deliver extra edge strength to prevent fraying and extend the useful life of the cover.
• Tailored Fit: An extra 5 ft of material provides full overlap beyond the pool edge to block wind and minimize gaps that let debris underneath.
• Secure Installation: Heavy-duty water bag loops spaced every 4 ft accept winter water bags to keep the cover anchored during storms and high winds.
• Evenly Spaced Grommets: The grommets offer additional fastening options for customers who prefer straps or cables for extra security.

Who It's For

This cover is best for inground pool owners who prioritize a robust, low-maintenance winter barrier that resists UV damage and wind uplift; it is a sensible choice for those who use water bags or grommet fastenings. The extra 5 ft overlap suits pools that need full edge coverage and homeowners who want a straightforward seasonal solution rather than a custom-fitted winter cover.

It may not be ideal for people who require a completely watertight or sealed safety cover, since some customers reported water collecting on or passing through the material in certain conditions. Buyers seeking a mesh cover to allow drainage or a rigid safety system should look elsewhere.

Pros & Cons

Pros

• Robust construction with a 12x12 scrim and triple-laminated polyethylene offers strong tear and cold resistance.
• UV-resistant thread and materials help protect liner appearance and pool water clarity over time.
• Extra 5 ft overlap and water bag loop spacing improve wind resistance and keep the cover in place.
• Evenly spaced grommets provide flexibility for additional fastening methods.

Cons

• As a general-purpose winter cover, it is not a rigid safety cover and may not meet all safety requirements for child or pet protection.
