In addition to the mild temperatures, we expect fewer than the typical number of fall storms through October. That should provide periods of pleasant weather for enjoying the fall foliage with more sunshine and fewer rainy days than normal. 

Fall Forecast 2025: Ontario and Quebec end of fall pattern - more active in November

However, a more active pattern is expected to unfold during November. Mild temperatures should persist well into November, but we are closely watching the potential for a more abrupt transition into early winter. This should allow ski areas to start their season close to on schedule.

Fall is often a tumultuous and changeable season, but this year we expect a milder season, especially through October. While there will be some chilly interruptions, above-normal temperatures are forecast to dominate, with fewer than the typical number of fall storms across the region, including Halifax, Charlottetown, and Fredericton. 

As we approach the end of the season, we expect a transition to a more typical late fall pattern, and temperatures should be near seasonal as we make the transition into early winter. 

After an exceptionally dry summer, the risk for wildfires and dry conditions will continue to be a concern through early fall, but we will see some improvement as we get deeper into the season. While most of the season should be drier than normal, a couple of low-pressure systems could tap into subtropical moisture (possibly the remnants of a tropical system), and this should bring precipitation totals close to normal.

Fall is typically a changeable and stormy season, but this year we expect a milder season compared to normal. Of course there will be some chilly interruptions, but above-normal temperatures are expected to dominate with fewer fall storms than we typically see across the province, including St. John’s and Corner Brook. However, as we approach the end of the season, we expect a transition to a more typical late fall pattern.
