Our take on September
The climatological peak of the Atlantic hurricane season falls on September 10 (NOAA). Also one of the wettest months. Quiet beaches and low prices for anyone who can be flexible.
Events in September
- Miami Spice restaurant months, Restaurants across Greater Miami.
Last edition: August 1 – September 30, 2026; next not announced (checked 2026-10-26).
Prix-fixe lunch and dinner menus, August 1 to September 30. Low season, so restaurants get busier while hotel rates stay low. Organiser
For the beach in September
- The water is bath-warm. Shallow bay water at Matheson Hammock and Oleta runs even warmer.
- Afternoon thunderstorms are common: plan the beach for the morning and leave at the first thunder.
- The midday UV Index is typically very high to extreme in summer (EPA puts Miami at about 10–11): shade from late morning to mid-afternoon.
