I guess it's what you're use to. Living in So Cal, I freeze my ass off when temps plummet into the low 60s. Nick Micale (and my friends from Hawaii) would freeze his ass off at my house while wearing a ski jacket when it was mid 70s. I'm not sure I could take it where you live when the temps were in the 130s. I will say that I'd rather be in too hot than too cold. At least you can pour yourself a beer.
