What September feels like
Convention season restarts after Labor Day and downtown gets its big festival weekend, so midweek is the calmer bet. The change is real but gradual: mornings turn pleasant well before afternoons do.
Real rain shows up maybe one day all month; the rest stay dry. The air runs dry — whatever the thermometer says, it wears easy. Most afternoons push past 90°.
