POOL WATER EVAPORATION RATES IN ARIZONA

Living in the great state of Arizona has many benefits including scenic views, beautiful weather, and the rare ability to swim throughout the majority of the year. With these benefits, also comes extreme summer temperatures that can affect your yard, air conditioning units, pool equipment and the water evaporation within your pool or spa.

A normal daily pool evaporation rate, especially in Arizona, is roughly a quarter of an inch. However, during the higher temperatures and lower humidity (June-August), your pool could potentially lose up to a half an inch of water per day. Over the course of a year, a 16’ X 36’ uncovered pool can lose up to 4-6 feet of water from evaporation in Arizona.

KEY FACTORS THAT INFLUENCE POOL WATER EVAPORATION

There are several factors that will affect the evaporation rates in your pool; Sunlight/Exposure, Humidity, Extreme Heat and Wind. The dry desert climate in Arizona will definitely accelerate evaporation rates, especially if your pool is in direct sunlight with little to no tree/foliage coverage. Along with too much sunlight exposure, wind can blow dry air over the pool and carry away water vapor from the surface of the pool, ultimately increasing the pool water evaporation rate.

Although pool water features create a wonderful ambiance in your backyard oasis, they continuously circulate and bring warmer water to the surface of the pool, causing greater evaporation into the air. Reducing the water feature run times will greatly lower the amount of evaporation inside of the pool, especially during the extreme heat of summer in Arizona.

HOW TO MINIMIZE EVAPORATION IN YOUR POOL

There are several ways to minimize evaporation rates within your pool, especially in the extreme temperatures of the Arizona summer. Adding trees & fences around the pool area can reduce wind and sun exposure, which will lower evaporation inside of the pool. Lowering the water level to halfway up the waterline tile can reduce the amount of water lost from splashing & swimming as well. Reducing how frequently the water features run or even keeping them off during the hotter summer months will also help with evaporation. Installing a solar cover for your pool will help lock in the heat and avoid the water vapor escaping into the air, especially during the cooler nighttime temperatures.

Regular maintenance on your pool, even including leak detection can also help identify any extra water loss inside of your pool or spa. If you notice the water levels in your pool or spa are dropping lower than the average evaporation rates, there’s a very good possibility you have a leak. If you have any questions or concerns about the amount of water your pool or spa is losing, do not hesitate to call Pinpoint Leak Detection for all your leak detection needs.
