Visiting Miami in December 2026?
December is Miami at its busiest: warm and wet, around 25°C / 77°F with rain on about 12 days, and Packed on 12 of 31 days.
In short, a hard sell — heavy crowds without the best of the weather.
Across the 12 months we forecast for Miami, December is the busiest of them all. Its heaviest day is Sat 19 Dec, busier than 100% of the year; its lightest is Tue 1 Dec at 58%.
⚠︎ Weekends run heavy — the 5th, 6th, 12th, 13th, 19th, 26th and 27th all sit Busy or Packed. If your dates can flex, a midweek arrival is the single easiest win.
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 →

Locked into a busy day? Here's the play.
- The heaviest port day is Sat 19 Dec — 4 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- Need flexibility? The 14th–16th is the month's calmest stretch — the easiest window to move around in.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
