As a retired meteorologist turned tour guide, I didn't expect that I would use my experience as a forecaster in my new career in tourism.

But here I am, finding myself answering more weather questions as a blogger than I ever did as a weatherman.

So, here are answers to some frequently asked questions about the weather in Boston in December.

If you're visiting at the end of the month, look into weather in January too!


December brings winter weather to Boston as the daily temperatures fall rapidly throughout this month.

Early in December, you can expect morning low temperatures in the mid-30s F (1 to 2 C).

However, by the end of the month lows will be in the mid-20s F (-3 to -4 C).

How Cold is Boston in December?

A couple of the colder mornings later in the month will see the temperature dip down into the mid-lower teens F (-10 to -11 C).

The record low temperature in Boston during December was -7F (-21.7 C)!

Afternoon high temperatures also will fall from the mid-40s F (7 to 8 C) early in the month to the upper 30s F (3 to 4 C) by New Year’s Eve.

A few of the warmer afternoons, early in December will produce afternoon highs in the upper 50s F (about 15 C).

The record high temperature in Boston during December was 76 F (24.4 C)!


About 16 days during December will be clear or at least partly sunny with 15 days on average being mostly cloudy.

How much Snow in Boston in December?

About 11-12 days will record at least .01 inches (0.25 mm) of precipitation, either rain or melted snow/ice but only 2-3 days will see heavy precipitation of 0.5 inches (13 mm) or more.


Snowfalls can vary a lot from year to year; however, the average December total snowfall is about 9 inches (23 cm).

The record monthly total snowfall was 27.9 inches (70.0 cm) set in 1970.

During December, you can expect at least 1 inch (2.5 cm) of snow on about 2 days with 3 inches (8 cm) or more on one day.

Snowfalls of 5 inches (13 cm) or more occur about once every other year. Snow is most likely during the second half of the month.
