Before we dive into what the next four weeks have in store, let’s take a closer look at how the season has played out so far.
The various shades of orange and red in the temperature anomaly map below highlight areas that have been warmer than normal since early September, while blue indicates cooler than normal temperatures. Note the absence of blue on the Canadian side of the border — this indicates that no area in Canada was colder than normal for this time period.
However, the last week of October saw a pattern reversal for parts of the country. The temperature anomaly map below shows that since October 20th, temperatures have actually turned cooler than normal in Western Canada. This pattern change finally brought much needed rain to BC, and also brought the first significant snowfall of the season to Calgary.

Meanwhile, temperatures were well above normal from Ontario to Atlantic Canada.
November temperature outlook
As we look ahead to the month of November, we expect the late October pattern to continue to dominate until early November. This will bring glimpses of wintry weather to Western Canada, and widespread cooler than normal temperatures are also expected across much of Northern Canada.
Meanwhile, much warmer than normal temperatures are expected from Ontario in Atlantic Canada, with temperatures most typical in late September and early October, especially during the first week of November.
By mid-November, wintry weather in western Canada will spread south and east across Central Canada and even into parts of Eastern Canada at times. However, we expect the focus of cold weather to remain across Western Canada and mild temperatures should make another appearance or two before winter ends.
As we head into late November, we expect a change in pattern, with a focus on colder weather spreading across Central Canada, including much of Ontario and western Quebec.

We’re not sure how quickly this pattern change will unfold, but once the cooler pattern settles in, we expect it to continue into early December. So make sure you enjoy the mild temperatures during the first half of November!

November precipitation outlook
November has a reputation for being a bleak and stormy month, but for much of Eastern Canada we expect fewer than normal storms. While the pattern in this region will become more active during the second half of the month, most of the region should see below normal precipitation totals for the month of November overall. Meanwhile, above normal precipitation is expected across much of southern BC. and in southern Alberta. For BC’s south coast, November is typically the wettest month of the year, so near-normal or slightly above-normal precipitation totals will be a dramatic reversal from the extreme drought conditions experienced through mid-October. Above normal rainfall is also expected in parts of eastern Manitoba, northwestern Ontario and northern Quebec. In early to mid-November, this region will be the battleground between colder weather to the west and milder weather to the east, resulting in an active storm track across the region. In summary, November will feature a transition from a mild fall pattern to a colder winter-like pattern. Does this mean a colder than normal winter is lurking around the corner?
