Best Things to do In Key West in September (2026)

Is September a Good Time to Visit Key West? You Bet It Is!

Welcome to the heart of hurricane season in the Florida Keys—but don’t worry, it’s still a great time to visit Key West. September may fall in the wet season, but if you’re flexible, it can be the perfect time for an unforgettable experience. Just keep an eye on the weather (and maybe invest in travel insurance).

Why visit Key West in September? Well, school is back in session, summer crowds are gone, and you’ll enjoy a little peace before the high season kicks off. It’s what I like to call the sweet spot of the year.

Key West Weather in September: What to Expect

Let’s talk Key West weather. On any given day, expect high humidity and average high temperatures in the mid-80s. Nighttime doesn’t cool off much—low temps hover around 80°F.

September is one of the wettest months of the year, with around 3 inches of average precipitation and over 20 days of rain. Yup, you’ll want a poncho.

But don’t worry! Rainy days in Key West just mean it’s time to explore indoor attractions like the Key West Museum of Art, the Key West Lighthouse, or Fort Zachary Taylor. Or, enjoy people-watching over a slice of key lime pie at a cozy café.

It can be a bit of a rainy season, this time of year… so what to Do on Rainy Days? So much to do!

Why September Might Be the Best Time to Visit

September brings a mellow, breezy vibe to the Conch Republic. Hotel rates tend to drop, the weather starts to mellow out (just a bit), and the island is refreshingly less crowded.

It’s the perfect time of the year to explore historic sites, take a walking tour through Old Town, or visit the Historic Seaport for cocktails and conch fritters.

Looking to relax under the palm trees? Head to Higgs Beach and soak in those crystal clear waters of the Gulf of Mexico and Atlantic Ocean. The water temperature stays warm—around 87°F—and it’s ideal for spotting marine life like tropical fish and sea turtles.

Water Activities you must check out in Key West

Water Adventures and Outdoor Activities

September still offers plenty of daylight for outdoor activities and Key West adventures. Try a snorkeling trip to our coral reefs, book a romantic sunset cruise, or head to Dry Tortugas National Park for a day trip to what feels like a private island.

Want something more low-key? Enjoy wine on a waterfront deck, watch the sun set with a view of the ocean, or stroll Duval Street for live music, tasty treats, and drag queen karaoke. It’s all part of the charm.

Toward the end of the month, the island starts buzzing with early events tied to Fantasy Fest—Key West’s biggest party. This annual 10-day party officially kicks off in late October, but the excitement starts early.
