Though the season officially shifts December 21st, it definitely feels like winter by the first week of December, though it's usually a milder month than Montreal in January and February. Still, a hearty down jacket is the best way to ensure a minimum of comfort as are thick gloves, a scarf and tuque, hat or hood.

  • Average December temperature: -5.6ºC / 22ºF
  • Average December high (day): -2.3ºC / 28ºF
  • Average December low (night): -8.9ºC / 16ºF
  • Record high: 15ºC / 59ºF
  • Record low: -33.9ºC / -29ºF
  • Precipitation**: anticipate 5 days of rain in December and 6 days involving light showers. Freezing rain a distinct possibility. As temperatures continue drop through the month, expect 12 days with light snow flurries and four days of heavier snowfall.

Montreal December Weather: The Lifestyle

Even though it gets cold in December, with the month marking the beginning of winter in Montreal, Montrealers don't generally get into hibernation mode until after the New Year. The hustle and bustle of Christmas holiday season might have something to do with it. The first half of December isn't that snowy either. By the time the second half of the month rolls around, it's holiday season and with it, time off.

**Note that light showers, rain and/or snow may overlap on the same day. For example, if Month X features an average of 10 days of light showers, 10 days of heavier rain and 10 days of snowfall, that does not mean that 30 days of Month X are typically characterized by precipitation. It could mean that, on average, 10 days of Month X may feature light showers, rain and snow within a 24-hour period.
