Key West, Florida Weather in April

April weather

April feels warm and humid, with long, sunny days and brief showers mixed in. The sea and waterfront suit snorkeling, boat trips, and time at Smathers Beach. You can also explore Old Town on foot or by bike, though sticky afternoons can make long walks tiring.

Rain falls on several days, but April is much drier than May. Keep flexible plans for an outdoor day: if a shower passes through, duck into the Key West Aquarium or browse shops along Duval Street. Don't count on a full day of rain, but don't expect every afternoon to stay clear either.

Events and crowds

The Conch Republic Independence Celebration brings parades, quirky events, and crowds to town in late April. Dates and activities vary, so check the schedule before choosing your days. Easter and school spring breaks can also make popular weeks busier.

If you hate crowds, avoid the festival dates and the busiest holiday weekends. April is usually a lively, popular month, with higher room rates than the quieter summer and autumn months. March can be even busier around spring break, while May brings hotter, wetter weather.

April in Key West: local tips

Travelling with kids? The shallow water at Smathers Beach makes an easy break between sightseeing stops, though the beach can feel busy during school holidays.

For a local tip, visit the Southernmost Point buoy early in your Old Town walk. The photo queue often builds later, and you'll be close to Duval Street and the Ernest Hemingway Home and Museum afterward. If showers interrupt your plans, the Key West Butterfly and Nature Conservatory offers a sheltered stop nearby.
