Key West, Florida Weather in December

December weather

December feels warm by winter standards, with highs around 24°C and lows near 23°C. You can wander Old Town, cycle past pastel houses, or take a boat out without summer's heavier heat. There's about six hours of sun a day, though cloud and occasional rain can interrupt outdoor plans.

Rain falls on around seven days, so a shower may briefly pause a walk along Duval Street. December is drier than November, but wetter than January. If you're planning a long day outdoors, keep an indoor stop like the Ernest Hemingway Home and Museum in mind.

Holiday season

Key West adds lights and local events to the month. The annual Key West Lighted Boat Parade brings decorated boats to the harbour, while the Harbor Walk of Lights brightens the waterfront. Christmas and New Year's bring a festive feel, especially around Old Town.

Travelling with kids? The lit-up harbour makes an easy evening outing, and you can combine it with a stroll along the waterfront.

Crowds and local tips

December is high season, and holiday weeks draw more visitors than quieter summer months. Expect busy sidewalks and higher hotel prices than in the low season. If you hate crowds, visit before the Christmas and New Year rush, or choose a quieter stretch of the month.

For a practical local tip, use the free Duval Loop bus to get between Old Town sights and the waterfront. It saves you from hunting for parking near popular spots. Key lime pie is a good reason to pause along the way.
