Key West in September
Average Temperature: 33°C
Visiting Key West, Florida, in September is a bit of a mixed bag. It's still very much summer vibes with the ocean calling your name and plenty of sunshine to soak up, but you should know it's also hurricane season. That means there’s a higher chance of rain and storms, so it’s smart to keep an eye on the weather forecasts and be flexible with your plans. The island tends to be less crowded than during peak winter months, so if you like a more laid-back atmosphere and want to avoid big tourist crowds, September can be a good time to explore without feeling overwhelmed.
On the plus side, the vibe in Key West remains super chill and welcoming, with plenty of bars, quirky shops, and historic spots to check out. You can still enjoy snorkeling, diving, or just lounging on the beach, but be prepared for the humidity and occasional afternoon showers. Plus, many hotels and resorts offer better deals this time of year, so it’s easier on the wallet if you’re looking for a budget-friendly getaway. Just pack a rain jacket, stay flexible, and enjoy the island’s unique charm even if the weather gets a bit unpredictable.
