What September feels like
September is the wettest stretch of the island's year and the deepest part of hurricane season, which is exactly why rooms are cheap and the beach is nearly empty. The Gulf is at its warmest now, and the hatchling releases draw quiet little crowds at sunrise.
Rain arrives about 8 days of the month, so keep one flexible day in your plans. Full tropical humidity: mornings are your friend, and shade is currency. Most afternoons push past 90°.
Can you swim?
The Gulf runs about 86° — bath-warm.
