What September feels like
September sits at the peak of hurricane season and is the month locals keep the radar app open, which is also why it is genuinely cheap. Southern Decadence takes over the Quarter on Labor Day weekend regardless of what the tropics are doing.
Expect about 6 days with real rain — enough to notice, not enough to plan around. Full tropical humidity: mornings are your friend, and shade is currency. about 13 afternoons top 90°.
