What September feels like
After Labor Day the traffic evaporates while the ocean is still holding its summer heat, which is why locals take their own vacations now. The International Boat Show mid-month is the single weekend that fills the hotels again.
Expect about 6 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 69° — brisk but swimmable.
