Nearly 112 Fahrenheit. It gets that hot sometimes in Fresno, California and then they open cooling stations so homeless people and other poor people don't die and you could take the bus for free if you were heading to a cooling station.

I never went to one. I stuck to shady microclimates and added Gatorade to my diet on such days.

If you are in that kind of heat, you need not just fluid but also electrolytes.

Also: Let me plug passive solar design. Even when it's hot like that outside, it doesn't have to be that hot indoors.

You just have to design it better.
