What September is like in Key West
September is the riskiest month to visit Key West. It sits at the peak of hurricane season, and a storm can close the Overseas Highway and force the Keys to evacuate. Highs are near 89F (32C), the air is heavy, and storms roll in most afternoons. Some small restaurants and shops close for a few weeks. It is also the cheapest and quietest month of the year.
This month is not a good fit for most travelers, especially families with fixed dates. Only very flexible visitors with refundable bookings and good insurance should consider it. For a safer trip at fair prices, wait for November, or go back to May.

Beat the crowds

- Cruise ship days crowd Old Town midday. Check the cruise schedule and plan museums for early morning.
Know before you go
- Hurricane season runs June 1 through November 30, peaking August through October. Storms can close the Overseas Highway and prompt evacuations of the Keys.
