Is March 2027 a good month to visit Key West?
Packed — March is Key West's busiest month: the typical day is busier than 91% of its year.
If you are coming for something that only happens in March, 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.
March is one of Key West's busiest months: warm and showery, around 25°C / 76°F, and Packed on 16 of 31 days.
It depends. The typical March day in Key West is Packed, and 21 of the 31 days in our window run Busy or Packed, so most days feel crowded. Expect around 25 °C by day, with rain on about 6 days. Public holidays in United States add to it. Cruise ships call on 23 of the 31 days. Early March is the month's quietest stretch in Key West — the typical day at 80%, against 96% in late March. For similar weather with fewer people, come in February or May. The crush is at Mallory Square at sunset; the quiet is at the old town's back lanes. The calmest day is Tuesday 2 March, the busiest Monday 1 March.
In short, worth it for the peak buzz, if you can take the crowds.
Among the 12 months we forecast for Key West, March ranks 2nd for crowd pressure. Its heaviest day is Mon 1 Mar, busier than 100% of the year; its lightest is Tue 2 Mar at 38%.
Preparing pays off in a month like this: timed-entry tickets and pre-booked tours turn the queue time into sightseeing time. see the options →
Nothing extreme to plan around — rain on 6 of 31 days.
