Is December 2026 a good month to visit Key West?

Packed — the typical December day in Key West is busier than 70% of its year.

If you are coming for something that only happens in December, that is the trade. If not, September is quieter.

Calm · Lively · Busy · Packed rank a day against Key West's own year — not a headcount.

December is Key West at its busiest: warm and showery, around 24°C / 75°F with rain on about 9 days, and Packed on 13 of 31 days.

Probably not. The typical December day in Key West is Packed, and 25 of the 31 days in our window run Busy or Packed, so most days feel crowded. Expect around 24 °C by day, with rain on about 9 days. Public holidays in United States add to it. Cruise ships call on 27 of the 31 days. Late December is the month's quietest stretch in Key West — the typical day at 68%, against 91% in mid December. For similar weather with fewer people, come in February or November. The crush is at Mallory Square at sunset; the quiet is at the old town's back lanes. The calmest day is Wednesday 9 December, the busiest Monday 7 December.

In short, a hard sell — heavy crowds without the best of the weather.

Across the 12 months we forecast for Key West, December is the busiest of them all. Its heaviest day is Mon 7 Dec, busier than 99% of the year; its lightest is Wed 9 Dec at 35%.
