After 2 days of the air temperature never reaching 70°, our pool temp was down to 71° this morning. 
No thunder storms here82 and thunderstorms.![]()
Solar heat is super effective this time of year through fall. Most days the temp control bypasses the panels a lot to keep pool to 91 max. Every now and then we get thunderstorms that bring it down to 88 or 89 briefly. I watch it closely since we swim almost every day around 6 pm and wife requires "9 handle" on temp. Once or twice per month I hit the gas heat for an hour if late T-storms drop below 90 late in the day.
