Over 40°. I went to meet up with friends and either they didn't show or I came at the wrong time. It ended up ok, I found a cool little DVD place and picked up Inception, Girl with the Dragon Tattoo and Dirty Harry for $20 total and got some nice bread with stuff in it but holy fuck was it and still is very hot. I bought three bottles of water and had been drenched with sweat the whole time.
When's the last time you personally found the weather boiling and how do you deal with it? When it's cold you just rug up and come home to a hot heater but if you're outside in the heat with a tshirt and shorts there's not much else you can do.
