I find that kind of funny, because it hit 115* in Phoenix this last week. I haven't seen a day with a high of les than 100* in months.
That's because you live in hell. It gets pretty hot here in Tucson, the highest I've ever seen it here was 119*...but, I have never been anywhere as hot a Phx. When we have 30 days over 100* Phx will have 60 days of over 110*...like living in a crock pot but without the benefits.
It's 72* right now, with a high of 93* expected. Personally, anything under 105* is pretty nice when you have 6% humidity.
