When I'm in office clothes and makeup, I can't stand the heat, but, ironically, if I'm working out or something active, I can deal.
We usually wait in the evenings until it's under 100 -- usually around 6:45 or 7. We do okay then, but it takes a lot more out of us when we do Saturday rides and don't get back in until 1 or 2. I'm assuming the difference is the intensity of the sunlight rather than actual heat for me (though I'd love 70s about now!!!). 100 without blazing sun = not too bad with lots of water. 90s with blazing sun = much harder. We had storms last week and did an evening ride in the 80s which was sooo much better - we were surprised how much faster we were.
