What September feels like
September is the peak of hurricane season on a barrier island, and that is the honest catch — Highway 12 overwashes, and Hatteras can be cut off for a while when it does. It is also the best month here by a wide margin, with warm water, beaches empty after Labor Day, and the fall run underway.
Expect about 6 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 78° — bath-warm.
