I have a 15 x 20 kidney shaped pool with a water fall off the spa that runs 24x7 and seem to lose a 1/2" to an inch a day. I should mention in Atlanta it was in the low to mid 90's and my water temp was 85 when I got home..Is this normal?
 
Evaporation is dependent on wind, humidity, water temperature versus overnight temperatures, etc.

In the summer, I will peak at about 1" loss per day. But my humidity is nearly zero.

Yes, this unnaturally hot May weather here in Georgia has got to be taking a toll on pool water. Evaporation can be expected. Usually I lose the most though in the Indian summer days of fall.
We normally can lose about 1/4 a day with 1/2 inch being on the hottest dry days.

You can prove this and rule out a leak, by performing a bucket test. Just search the forums for how to do one.

You all have been hot, we have been 20-25 deg below normal! It was only in the mid 70's here today. Normal Memorial Day weather can be easily in the low 100's.

Surprisingly our weather has been very unseasonably cool. Have had to keep the solar cover on it far longer than every before. High and Low temperatures have been 20-30 deg below normal.
