I'm with you, Lin. Not at all tolerant of the hot, humid days. My solution is to travel in the summer to cooler places . . well my kids are in Salt Lake City and it's forecast to go over 100 there but at least it is DRY. I can work outside until noonish there, then again in the evenings very happily.
Otherwise, I make it very short forays into the garden, 10 minutes or less if the sun is out. That way I keep my head from pounding, and can recover with a little rest at the computer, and a cool drink. It's amazing what I can get done in a 10 minute dash - just sprayed all my orchids, and filled the watering cans from the rain barrels at the same time - so IF the rain comes later there is room in the barrels.
It rained heavily on Sunday afternoon, and after that whole thing went by MY MY, it was lovely outside, down around 80, breezy and felt cool. Such a treat.
