 take the outdoor temperature and add 30 to 40 degrees. That's how hot it is in some of these attics. A couple years ago, it was 109 out. It was 146.5 degrees in an attic we were doing an install on. Literally everything you touch burns you. You're 15, 20 minutes at a time at most in the attic, and then you've got to get back down, cool off, get some water.
