I don't mind what the temp is during the day to be honest. If I'm working, I work in an a/c'd office so that helps obviously. If I'm off, we do something accordingly. Last Saturday was 40-odd, we flitted between a couple of shaded beer gardens and, believe me, it was very tolerable.
We have r/c and a pool at home so they're an obvious benefit but I wouldn't say the heat has ever really stopped me doing anything.
30 degrees at night is a different matter, that's a nuisance. Although the a/c and the ceiling fans work well.
