Every year people get heat related illnesses, and some die from a lack of understanding about dehydration, sports physiology etc. High temps, especially above 100° calls for reduced exertion,
proper hydration, (meaning not just sucking down a whole bunch of bottled water). Drink only "pure" water, and no food, your electrolytes go out of wack. And if that happens, and you're lucky- next stop ER.
Be smart about heat. I'm ok up to a heat index in the high 90s as long as I keep my jersey wet, and drink things with electrolytes.
Edit:
I just got off my bike. With plenty of fluids, and on a low intensity ride, I was almost home (luckily)when my body decided "enough." No sign of anything up to the 23 mile point of a 25 mile ride. I had drunk 3/4 my water bottle, and felt fine. I decided to ease up completely, and cool down. In the next flatish mile, my quads started really losing strength (more than hurting - shut up legs) and then my TRICEPS started cramping. That's a new one for me. Any farther from home, I would have stopped to rest. Rode 1/2 mile sitting up on an empty MUP, and finished the last bit on the road. I never experienced such a dramatic bonk before - no diziness, etc. and now feel good to go after a few minutes resting in 74° and some water.
Only 93° out... But factor in heat absorbtion/radiation of tarmac, heat discharge from vehicles blasting their AC and direct sun, well... It feels hot to me.
