It's even hotter down on the field because the field is below grade. When they built the stadium, they dug a big hole for the field and used the fill around the edges to brace the stands. The top of the north end zone (until the endzone expansions in the 80s and 90s) was even with the road and the bleachers on the south side were only a little bit above grade. That made it bad enough, but now, with the expansions on both end zones raising the seats well above grade, all breezes are blocked. When I was a freshman (in 73), we all played frisbee on it. (It had artificial turf, aka Doug's Rug, so the school figured it was no harm to let students on it.) The thermals from Doug's Rug and the lack of a breeze made them fly forever. A great frisbee venue, but, it sucked for pickup football - hot as hell and rug burns galore.
