Boston, Massachusetts Weather in December

December weather

Boston feels properly wintry in December. Daytime highs average 4°C, and nights dip below freezing. Rain falls on 11 days, with plenty of cloud and only a few hours of sun each day. It can feel damp and raw, so outdoor sightseeing may wear you down faster than the cold alone suggests.

You can still enjoy the Boston Common holiday lights or skate at Frog Pond. Museums such as the Museum of Fine Arts make good breaks from wet weather. The Freedom Trail is less appealing in cold rain, especially when you're walking between outdoor sites.

Holidays and crowds

Christmas brings decorated shop windows along Newbury Street and seasonal events around Boston Common. The Boston Pops' holiday concerts are a local tradition, while Hanukkah events vary with the calendar.

December is generally quieter than Boston's busy autumn, though the holiday period draws more visitors. Early in the month, you may find a calmer city and better hotel rates than during fall foliage season. Prices can rise around Christmas and New Year's, so don't expect every week to be a bargain.

Making the visit work

Families who enjoy skating can spend a cheerful afternoon at Frog Pond, then warm up with clam chowder nearby. For a more comfortable day, pair indoor sights with short walks through Beacon Hill, where the brick streets and decorated doorways feel especially seasonal.

A practical tip: use the MBTA to reach the Museum of Fine Arts rather than trekking there from Back Bay in cold rain. The Green Line's E branch stops close to the museum, saving you a long outdoor walk. Check the museum's opening hours before setting out, since holiday schedules can differ.
