It depends a lot on the temperature and humidity. Here in Southern Arizona it is 110 degrees and 10% humidity (hot and dry) right now, and my pool loses about an inch every three days or so. Wind is also a major factor in evaporation. The quicker the moisture is pushed off the top of the pool the faster it is replaced with more. Windy equals increased evaporation rates.
