Weather
Highs 85–88°F, lows 70°F by month end. Water still 82°F. Humidity drops noticeably the last week. Hurricane risk still real until mid‑month, low after.
Prices
First two weeks are still summer rates ($250–$400/night beachfront). The last week begins the climb toward winter season — book the early half if you can.
What to book first
- A sunset cruise — the light starts getting that winter golden quality.
- Stone crab opening dinner — season opens October 15.
- A morning shelling tour — fall storms wash in great shells.
What to skip
Halloween weekend rentals at peak rates — they jump for that one weekend, then settle back down.
One local note
Stone crab opens October 15 every year. The first week's catch is the most plentiful and least picked over — eat it then if you can.
