Timing end of charge to departure time on warm days?

I understand that timing the end of home charging to coincide with your trip departure time is great for very cold days since the battery doesn’t have to heat itself as much while driving.
My question is: does this make sense on warmer days as well? At what outside ambient temperature would this strategy make driving more inefficient because the battery is too hot?
I live in NorCal where in the morning it can already be in the 80 degree range. On these very hot days should I try to get charging done during the earlier portion of the off-peak electric rates (ie 12am-3am instead of 5am-8am)?
