A Palmdale swimming pool can lose more water in July and August than most homeowners expect. With summer temperatures reaching 110°F or higher, intense high-desert sunlight, low humidity, and frequent wind, evaporation is a constant issue. A pool may lose roughly 1/4 inch of water per day during extreme weather, and even more when strong winds push across Lancaster, Quartz Hill, and the open Antelope Valley.
That loss adds up quickly. A pool measuring 15 by 30 feet has about 450 square feet of surface area. Losing 1/4 inch daily means roughly 70 gallons of water evaporating every day—before accounting for splashing, filter cleaning, or a plumbing leak. Tumbleweeds, Joshua tree debris, sand, and dust also make local pools work harder, which can lead to unnecessary cleaning and water use.
The goal is not to avoid topping off a pool altogether. The goal is to identify normal evaporation, prevent avoidable loss, and keep the water balanced so you are not draining the pool unnecessarily.
