What to pack

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°.
