How the weather will look like in December in Ontario

Winter is shaping up to be a season of surprises—picture snow shovels at the ready, dreams of a white Christmas and just enough unpredictability to keep it exciting.

The Farmers’ Almanac—a trusted guide for weather predictions since 1818—has mapped out a season of chilly temperatures, fluctuating snowfall and the kind of winter wonderland moments we love (and occasionally grumble about). Whether you’re dreaming of snow-covered streets or dreading icy commutes, here’s what’s in store for residents in Ontario.

This past fall brought a mix of sunny days, cool breezes, and sporadic rainfall, with relatively mild conditions in southern Ontario.

As the season shifts to winter, colder and wetter weather patterns are predicted, though substantial snowfall may be intermittent, particularly in November and December.

November began with a mix of lingering fall vibes and early winter hints. From Nov. 1 to 9, southern Ontario experienced scattered rain showers in the south and snow showers in the north.

Sunny spells and cooler temperatures are likely between Nov. 10 and 21, keeping precipitation light during this period.

By Nov. 22, colder weather will settle in, potentially causing lake-effect snow near areas like Lake Huron and Georgian Bay. Light snowfall will extend across the region as the month wraps up.

On average, November’s temperatures will hover around 2 C, with precipitation totals at 75 mm—wetter in the east and drier in the west.

December begins with typical early-winter patterns. From Dec. 1 to 9, northern areas will see consistent snowfall, while southern Ontario is anticipated to alternate between rain and snow showers.

Heavier snow could arrive between Dec. 10 and 13, hinting at a magical winter scene just ahead of the holidays. But will Christmas sparkle with a white blanket of snow? A warm spell from Dec. 14 to 19 may bring rain or mixed precipitation, melting much of the snowpack.

Milder temperatures are expected to continue from Dec. 20 to 28, but colder air may sweep in by Dec. 30–31, offering a chance for fresh snowfall just in time to welcome the New Year.

This year, December’s average temperature is forecast at -2 C, slightly above normal with precipitation around 80 mm.

As January and February (2025) approach, southern Ontario is expected to settle into a more traditional winter pattern, with colder temperatures and increased snowfall. Significant snowstorms are most likely in mid-January and late February, making the latter half of winter one to watch for winter sports enthusiasts and snow lovers.

Western Canada is set for a milder but wetter winter this year. Southern Alberta, including Calgary and Lethbridge, will see a mix of rain and occasional light snow, while the West Coast cities of Vancouver and Victoria can expect predominantly rainy conditions, with flurries being a rare occurrence. Saskatchewan, in contrast, will face colder-than-average temperatures but will see fewer storms compared to Ontario.

As always, weather patterns can change, so it’s wise to visit the Farmers’ Almanac for up-to-date forecasts.
