Winter seasonal outlook

Meteorologically speaking, winter is officially upon us since December 1st! However, with many regions in Canada having experienced winter-like conditions in November, some may say that the official start of winter comes a bit late.

Here is our temperature outlook for this upcoming winter season:

Over the next three months, the above-average temperatures experienced during the fall are expected to continue for most of the eastern part of Nunavut, the Atlantic Provinces, Quebec, and most of Ontario (except for the northwestern region). On the other hand, colder-than-normal temperatures can be expected in parts of western Nunavut, Northwest Territories, and southern Yukon, as well as in northern British Columbia, Alberta, and Saskatchewan.

A weak La Niña pattern is forecast to persist through the winter for a third consecutive year. This could contribute to the colder-than-normal winter temperatures forecast in parts of Western Canada.

Recap of fall 2022

Temperatures were above-average across the whole country during the months of September, October and November. A persisting blocking ridge amplified some of the warmer-than-normal temperatures that Western Canada experienced in October. A blocking ridge is a high pressure that remains stationary over a region for several days or weeks, preventing weather systems to go through.

Temperature anomaly (difference from normal) for the months of September, October and November. The map shows that the average temperature for the three months has been above normal.

Most of the country received below-average precipitations during the fall. This was especially apparent in British Columbia, where the blocking ridge persisted and prevented precipitation for much of the fall. The Great Lakes region in Ontario also experienced an extremely dry fall. On the other hand, the Atlantic region received above-average precipitation, mainly during the month of September, following the passage of hurricane Fiona.
