What September feels like
September is when the hurricane season means it, and the king tides begin — you will see seawater rising up through the storm drains in Brickell and along the Beach on a perfectly clear day. Regulars plan around both and still call it the best value of the year.
This is the wet season: rain on about 13 days, so pack accordingly. Full tropical humidity: mornings are your friend, and shade is currency. about 15 afternoons top 90°.
Can you swim?
The ocean runs about 87° — bath-warm.
