Pool Water Evaporation in Winter Florida

The picture above illustrates a very typical condition of a pool during sunrise. The temperatures overnight are between 40-50 Fahrenheit and the pool temperature is around 80-85 Fahrenheit. This strong difference will create heavy evaporation. You can avoid this by using a solar cover or any similar type of pool covers. The location of your pool also plays a big role as to how much water will evaporate over time. For example, the exposure of the pool. Is it more covered by shade and trees around your property or is it exposed directly by the sun light during the middle of the day? Below have 5 main reasons listed that could answer your question.



• Low rainfall

Any of the previous mentioned reasons should help in determining if your pool is leaking. The easiest way to test a leak is buy conducting a bucket-test. Place a bucket on your pool steps and use heavy stones to keep it down. Then mark your water level on the inside and outside of the bucket, this way you can easily check if the water level drops. After a day you should be able to tell a difference. In case the water level outside of the bucket is lower than on the inside the bucket, you have a leak.

How do I keep my pool water level up?

The pool service will arrive weekly at the property to readjust the water level of your pool. In case the water evopartion is stronger, we advise the guests to use the nearby hose and fill it up by themselves. We have installed mechanical pool hose timers. They work like an egg timer, simply twist the dial to around 30-45 minutes and let it run. After the time has expired, it will turn off automatically.
