Normal evaporation this time of year

Live just outside of Boston and I seem to really be losing a lot of water due to evaporation the last 2 weeks.. I have a pump seal leak that is getting repaired this Thursday, but I have my equipment off when not needed. I thought I may have another leak some place else, but when I put my solar cover on mid last week the water loss really slowed down. Last night after cleaning the pool I forgot to put the cover back on, but pumps were off, and noticed in 24 hours I lost just over .75 inches. Temps this morning were in the upper 40's. Water temp is 60. Is this normal for this time of year up in New England?

Could be. Really hard to say. Dependent on your local environment.

I am losing 1/4-1/2” of water a day with pool in the 80s and nighttime temps in the high 50s-low 60s.

This time of year is when I traditionally lose the most water daily. I call it my Indian Summer loss. Right now I'm keeping the autocover closed more than normal due to the fall leaves dropping and the water losses.
