Torontonians may be focused on getting through the latest stretch of hot, humid weather (and hiding out from thick, smoky skies), but The Old Farmer’s Almanac is already looking past patio season and into fall.
The publication recently released its Fall 2026 weather forecast, where temperature predictions are compared with a 30-year statistical average prepared by government meteorological agencies.
Canada as a whole can expect a milder fall, with warmer-than-average temperatures, although parts of central and northern Canada and southwestern British Columbia can expect cooler weather.
Southern Ontario can expect a cooler start to the season, followed by more typical temperatures and a wetter-than-normal pattern.
“September is expected to be cooler than normal before temperatures return close to normal in October,” the Almanac predicted.
Torontonians might also want to keep their umbrellas nearby. Most of Canada is expected to experience above-average precipitation this fall, with much of B.C. being the notable exception.
“Rainfall will be well above average in the east, and slightly above average in the west,” the Almanac said of southern Ontario.
For context, Toronto typically reaches a daytime high of 22 C in September, with a daily mean temperature of 17.9 C and about 69.4 mm of precipitation over the month. If the Almanac’s forecast is right, then September’s average temperature could fall below those benchmarks.
By October, Toronto’s average daytime high falls to 14.6 C and its daily average temperature drops to 11.2 C, while the city receives a similar 69.1 mm of precipitation. With the Almanac predicting a return to near-normal temperatures that month, conditions could fall closer to October’s typical forecasts.
For now, we still have some time before the cooler weather sets in! While it’s still nice out, check out these 35 essential summer day trips from Toronto for 2026.
