However, the rate of evaporation is different in outdoor pools and indoor pools. Several factors like humidity, wind speed, and temperature play an enormous role in determining how fast the water of an outdoor pool evaporates.

The evaporation rate increases when there is low humidity, and the wind speed and pool temperature is high. People living in windy areas use various techniques to eliminate these problems. They grow shrubs and trees near the pool. Some people even install windbreakers to make sure that the rate of evaporation is as low as possible.

Even though the environment does not affect indoor pools, numerous other things do impact it. Indoor pools often require ventilation to control and maintain the humidity of the premises which is primarily due to evaporation.

Not only that, you have to continually readjust the windbreakers to make sure that it does not block the sunlight from the pool, which is a tiring job. On the contrary, you have to install the pool covers, and that is it.
