solar cover on/off for best heating?

[ePoolUser]

Our water was 78F at 12" when I opened the pool 2 weeks ago.

Over the past week, the weather has been generally calm with sunny warm days, 85-88F and cool nights, 55-65F. With the solar cover on 24/7*, the first 3-4" of water (at the surface) have hit a hot 95F repeatedly (pump off all day). At 12" the temp is 84, at 2' the temp is 80. *We remove the cover and swim for about an hour every evening and replace the cover.

I can't imagine the surface getting so hot without the cover. Would the water warm more evenly and deeper with direct sun rays? Idunno.

I am in the Nashville, TN area. If you are in this area without a solar cover, what are your temps?
