What September feels like
Second summer, locals call it: the calendar says fall and the thermometer disagrees, and UT home games start in heat that flattens people who flew in for them. The first real front usually lands near the end of the month and the entire city notices.
Expect about 4 days with real rain — enough to notice, not enough to plan around. Most afternoons push past 90°.
