Does extreme heat damage a boat stored outdoors in Arizona?

May 11, 2026

Yes — Lake Havasu summer temperatures above 115 degrees F cause significant damage to uncovered boats over time. Direct sun degrades gelcoat (causing oxidation and chalking), cracks vinyl upholstery, dries out rubber seals and gaskets, warps plastic components, and shortens battery life. Extended outdoor exposure without a quality UV-resistant cover will noticeably age a boat within 2-3 seasons in Lake Havasu's climate.
