Plan for a winter that brings near-normal temperatures across most of Canada, but with significant regional variation in snowfall and storm activity. The 2024–2025 outlook points to a weak La Niña pattern influencing the season from December through March.
What is the winter weather forecast for Canada this year?
Environment and Climate Change Canada projects temperatures near seasonal averages for much of the country. British Columbia and the Prairies may see slightly colder conditions early in the season, while Atlantic Canada faces an increased chance of above-normal precipitation. Northern regions, including Yukon and Nunavut, should expect typical deep cold but with fewer extreme cold snaps than last year.
How will La Niña affect winter storms and snow?
Weak La Niña conditions typically shift the jet stream northward, bringing wetter weather to the Pacific Northwest and central Canada. This means more snow for the Rockies and southern British Columbia, especially in January and February. Ontario and Quebec may see a mix of snow and freezing rain, with a higher risk of prolonged snow storms in the Great Lakes region. Atlantic provinces should prepare for active storm tracks, which can bring heavy snow followed by rain events.
Will this winter be colder than last year?
For most of Canada, this winter will feel similar to last year, with near-normal temperatures. The Prairies and British Columbia may see a colder start in December, but a warm January is possible due to the weak La Niña pattern.
When will the snowiest period occur?
Late January through early March is the typical peak for snowfall across southern Canada. For the Rockies and British Columbia interior, December often brings the heaviest accumulations. Check the 10-day forecast for local timing.
