What September feels like
September carries the highest odds of a storm all year, and Fort Myers has more recent reason than most to say so plainly — the islands rebuilt after Ian and the causeway traffic tells the story. Rates bottom out and the regulars go back to the water on the good days.
Rain arrives about 11 days of the month, so keep one flexible day in your plans. Full tropical humidity: mornings are your friend, and shade is currency. about 20 afternoons top 90°.
Can you swim?
The Gulf runs about 86° — bath-warm.
