Ontario Fall Forecast 2026: What Toronto Can Expect This Autumn
After weeks of heat, humidity, and smoky skies, many people are already looking ahead to cooler days. The Old Farmer’s Almanac has released its long-range fall forecast for 2026, offering an early look at what Ontario could experience over the next few months. While seasonal forecasts aren’t guaranteed, they can give a general idea of what weather patterns may develop.
A Cooler Start to Fall
For southern Ontario, including Toronto, September is expected to be cooler than normal. If you’ve been waiting for a break from the summer heat, the first month of fall could arrive with more comfortable temperatures than usual.
October Looks More Typical
The cooler pattern isn’t expected to last all season. According to the forecast, temperatures should return to near-normal levels in October, making for a more typical fall across the region.
Expect More Rain Than Usual
Rain could play a bigger role this autumn. The forecast calls for above-average rainfall across southern Ontario, with eastern parts of the province expected to receive the most significant increase. Western areas, including the Greater Toronto Area, could also see slightly wetter conditions than normal.
That could mean more rainy weekends, so it may be worth keeping an umbrella nearby if you’re planning apple picking, hiking, or other outdoor fall activities.
