Key West, Florida Weather in July

July: hot and showery

July feels sticky from morning onward, with highs around 30°C and humidity at 75%. Rain falls on 24 days, often as a sharp shower or thunderstorm, so a sunny start doesn't promise a dry afternoon. You'll still get plenty of daylight, but the comfort score is poor.

Save walks around Old Town and the Southernmost Point for earlier in the day. A shower can make a museum stop at the Key West Shipwreck Treasure Museum welcome. The water stays tempting, but avoid making a long boat trip your only plan; storms can disrupt time on the water.

Festivals and holiday crowds

The Fourth of July brings celebrations and fireworks, while Hemingway Days usually takes place in mid-July. Look for the Hemingway look-alike contest around Duval Street. These events add a lively feel, but they can make central streets busier.

If you hate crowds, skip Duval Street during the contest and explore the quieter lanes near the Key West Cemetery instead. July is generally less crowded and less expensive than the winter high season, though holiday dates and Hemingway Days can be exceptions.

Make the weather work

Travelling with kids? Keep a rainy-day stop in mind, such as the Key West Aquarium on Mallory Square. For outdoor time, Fort Zachary Taylor Historic State Park offers a beach and shaded paths, but the heat and humidity can wear you out quickly. Avoid planning a long exposed walk in the afternoon.

A local tip: check the ferry conditions before setting off for Dry Tortugas National Park. The boat leaves from Key West, and rough weather can affect the trip. Keep a flexible plan on the island, too, as July rain may interrupt beach time.
