Wednesday, September 22nd 2021, 5:24 am - Will it be a more traditional fall season across Canada, or is winter lurking just around the corner? Here's what to expect over the next three months.
Historic heat, severe drought and wildfires dominated headlines across Canada during the past summer. However, summer heat quickly gave way to more typical early fall weather across Canada during early September. Can we now expect a more traditional fall season across Canada? Or is winter lurking just around the corner?
While most of Canada saw an early arrival of cooler early fall weather, warm weather is not finished with much of Canada just yet. Late September and October will feature periods of pleasant fall weather with near seasonal or above seasonal temperatures.
Here is a look at our temperature forecast for the remainder of September, October and into November.

Most of Canada should see near normal or above normal temperatures, with the warmest weather relative to normal extending from southern Manitoba to Newfoundland.
However, we do expect a pattern reversal late in the season. For Ontario, Quebec and parts of the Maritimes, this should bring a quicker start to winter than we have often seen during the past 25 years. We have become accustomed to very mild Decembers, but this year should bring more typical amounts of winter weather during the weeks leading up to and through the holidays.
Meanwhile, across Western Canada, we expect that the arrival of consistent cold weather will be temporarily delayed.
Across most of Canada, we expect near normal precipitation totals for the fall season. However, for most of B.C., we expect above normal precipitation. Most of Atlantic Canada could also end up wetter than normal as the tropical season continues to be very active.
Below is a more detailed look at what we expect across Canada over the next three months:
Near normal temperatures are expected across most of B.C., but southern areas should be slightly warmer than normal. A typical number of fall storms and rainy days are expected, but this should result in above normal precipitation totals as moisture-laden systems will bring a heightened risk for excessive rainfall at times. Mild temperatures are expected for the end of fall and continuing into December.
WHAT’S TO FOLLOW B.C.’S HISTORIC SUMMER:
Near normal temperatures and precipitation are expected across Alberta. This will be quite a contrast to the drought conditions that dominated the year so far, helping to replenish the groundwater supply. While many areas have already seen an early frost, warmer than normal weather is expected to dominate during the final week of September and continue through early October. Of course, a normal fall will typically include a few shots of early winter weather. However, we expect that the arrival of consistent cold will be delayed with above normal temperatures expected for December.
SASKATCHEWAN AND MANITOBA
Alternating periods of above normal and below normal temperatures should come close to offsetting each other from mid-September through December, resulting in near normal or slightly above normal temperatures for the season. Parts of the region have already seen an early frost, but warmer than normal temperatures are expected to dominate during the final week of September and continue through early October. Precipitation totals are expected to be near normal, which will help to replenish the groundwater.
