When temperatures are hitting record highs, you will notice more evaporation. Hot days and cool nights are the perfect recipe for pool water evaporation. Exposure to sun and wind also contribute highly to evaporation. If a pool has direct sunlight all day, has no screen, or fence to block the wind, they add to the evaporation. Lastly, the humidity (or lack of humidity) plays a role as well. The more dry the air is, the more evaporation occurs.
When considering if your water loss is due to pool evaporation or a leak, consider these factors and perform a bucket test. To help reduce pool water evaporation invest in a pool cover. A well-fitted pool cover used daily significantly reduces evaporation.
