In this blog article, Sherleak Holmes, the pool leak inspection expert, will discuss the average evaporation rates of swimming pool water in Florida.

For those lucky enough to have a backyard swimming pool in the Sunshine State, keeping it filled can be a chore during the hot and humid Florida summers. With average high temperatures from May through September ranging from the mid-80s along the coasts to the low 90s further inland, pool water evaporates at a rapid rate. Determining and understanding normal evaporation rates is key for pool maintenance.

The rate at which pool water evaporates depends on several environmental factors – temperature, humidity, wind speed, and the amount of direct sunlight the pool receives. In Florida’s summer climate, with abundant sun and high temperatures, pools can lose from 1⁄4 to 1⁄2 inch per day. For a 20×40-foot rectangular pool, that equates to 1,000 to 2,000 gallons each day!

To offset these significant water losses, it’s recommended that Florida pool owners check their pool’s water level at least 2 to 3 times per week. Topping off with a garden hose usually does the trick. But during the hottest, driest weather, some pools may need replenishing daily. This prevents the skimmer from sucking in air or the pump from burning out due to low water levels.

The eastern and southern coastal regions of Florida tend to have slightly lower evaporation rates thanks to the moderating influence of the Atlantic Ocean and Gulf of Mexico. Hot inland locations like Orlando, however, with less ocean effect, are prone to higher evaporation levels.

Pools shaded by structures, landscaping, or backyard trees see less sunlight and therefore evaporate at diminished rates. Uncovered pools bake in the sun all day, driving increased water loss. Properly balancing chemicals is also important since evaporation concentrates salts, chlorine, stabilizers, and other contents.

For homeowners trying to budget and plan ahead, approximately 1⁄4 inch daily water reduction is a reasonable average evaporation estimate for Florida swimming pools. This equals 600 to 1,200 gallons per week for typical home pools. Having an evaporation cover handy during vacations and rainy periods can also cut down on replacement water needs and help conserve usage.

Owning a pool, although often viewed as a luxury, requires diligence and year-round care in the Florida climate. By comprehending the impact of environmental conditions and the projected evaporative water loss based on a pool’s size and exposure, owners can better maintain safe, consistent, and enjoyable water levels. A little preventative monitoring goes a long way towards relaxing poolside without constantly fighting a losing battle against the infamous Florida heat and humidity. Beating the evaporation game just comes with the territory for residents all across the Sunshine State.
