Right now it's about 32 degrees C here which I suppose is over 100 in F, and it's pretty much ideal. I'd say I cannot tolerate anything under 15 without breaking into shivers which is around 60 F.
For me anywhere around 22-32 is ideal, although 35 is tolerable (not at first but)
Change to Celcius already you miserable bastards, 100+ degrees sounds ridiculous
