What October feels like
October is the islanders' month, and the Concours d'Elegance brings the car crowd down for one weekend at the end of it. The oyster boats start working the creeks again once the water cools, and rentals drop back to spring rates.
Expect about 4 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
Can you swim?
The ocean runs about 73° — comfortable for swimming.
