December is Boston with the crowds gone — Calm every day, cool and wet, around 6°C / 43°F with rain on about 11 days.
Yes, if the weather does not put you off. December in Boston is Calm on the typical day, and not one of the 31 days in our window is crowded enough to call Busy. Expect around 6 °C by day, with rain on about 11 days. Public holidays in Canada and United States add to it. No week of December is meaningfully quieter — the typical day is Calm throughout; pick by day instead. The crush is at Faneuil Hall and Quincy Market; the quiet is at the Esplanade and the Charles banks. The calmest day is Tuesday 1 December, the busiest Friday 25 December.
In short, quiet and wide open, if the weather doesn't put you off.

Which week of December is quietest in Boston?
No week of December is meaningfully quieter — the typical day is Calm throughout; pick by day instead.
The upside of a quiet December
- Walk straight into the sights that sell out in high season — no timed ticket, no queue.
- This is a wing-it month: nothing needs locking in.
- Early on, you can have the busiest spots almost to yourself — bring a camera.
No queues to skip, and nothing to book ahead — that's the whole point.
December weather in Boston
Cold — around 6°C / 43°F, so pack a proper coat, with rain on about 11 days, so keep a layer handy. Daylight is short, about 9 hours, so plan the big sights for the middle of the day.
This is the value month: no need to book far ahead, and the freedom to change plans on the day is part of what you're getting.
