What September feels like
September is the local favorite and the local gamble at once — the ocean is still summer-warm, the Boulevard is quiet, and it is the peak of hurricane season on this stretch of coast. It is also the wettest month of the year, though the rain tends to come in a few big events rather than steady drizzle.
Expect about 6 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 80° — bath-warm.
