We still have a long way to go before Sept. 22, which marks the official start of fall, but if you’re already dreaming of pumpkin spice and cooler days, the Farmers’ Almanac Extended Fall Forecast for 2025 has dropped, and Ontario’s upcoming season is shaping up to be anything but predictable.
So far, Ontario’s weather this summer has been a rollercoaster to say the least, with a mix of unseasonably chilly stretches followed by waves of scorching heat, which might have you wondering what fall might bring.
According to the long-range forecast, Ontario is expected to start the season on a cool and dry note, but don’t get too comfortable. By October, conditions will slowly grow more unsettled and colder, which will set the stage for a stormier and rough second half of the season.

Rain will, unfortunately, become a recurring theme, with heavy showers and even thunderstorms expected across Ontario and Quebec throughout October. Thanksgiving, which falls on Oct. 13 this year, will be one of the brighter periods of the season, bringing a temporary break in the unsettled weather.
Much of Ontario is expected to enjoy pleasant and partly sunny skies, perfect for one last outdoor gathering with the family before the frigid air settles in for good.
Things will take a sharp turn on Halloween, as the forecast for Oct. 31 suggests a chilly evening with fair skies early on, followed by increasing clouds and a risk of showers, so if you’re planning to head out trick-or-treating, you might want to consider incorporating some waterproof elements into those costumes.
Snow isn’t out of the question either, especially in higher elevations of northern parts of the province. By November, more widespread snowfall is expected to appear across Ontario, and winter inches closer and closer.
Across the rest of Canada, this fall looks equally turbulent, with the Prairies and Atlantic Canada expected to see cooler-than-average temperatures, with wet snow possible as early as October. In contrast, southern Ontario might enjoy some of the most temperate days of the entire season, particularly in early October and mid-November.
Overall, fall will be a season of dramatic temperature swings, precipitation, and some moments of calm.
However, don’t worry about the chilly season just yet. We still have a few more weeks to enjoy summer, so make sure to soak up every warm day while you can.
