So far, Ontario has experienced a summer of extremes, with scorching temperatures and heavy rainfall. As the season transitions into fall, the weather is expected to stabilize somewhat.

According to the Farmers’ Almanac, from Aug. 1 to 11, the weather will feature isolated thunderstorms followed by a spell of sunny and cool days.

The period from Aug. 12 to 23 will bring showers and cooler temperatures, while Aug. 24 to 31 is expected to see a return of isolated thunderstorms with warmer conditions.

Overall, August is predicted to have an average temperature of 19 C, which is slightly below the norm, and precipitation is forecasted at 70 mm— 10 mm less than previous years.

As September approaches, the weather will begin with scattered showers and cooler temperatures from Sept. 1 to 6.

From Sept. 7 to 9, residents could see a tropical storm threat.

Between Sept. 10 and 19, southern Ontario will enjoy sunny conditions, while the north may encounter a few showers as temperatures gradually cool down.

Later in the month, from Sept. 20 to 30, showers with warm temperatures will change to cooler weather.

September’s average temperature is expected to be 15 C, slightly above average. Total precipitation is forecasted at 85 mm — nearly 25 mm below average in the north and 15 mm above average in the south.

The Farmers’ Almanac anticipates generally favourable conditions with the arrival of October.

Thanksgiving, which falls on Oct. 14 this year, is expected to be fair and dry— ideal for outdoor celebrations and gatherings.

Similarly, Halloween is forecasted to bring dry weather, ensuring a pleasant experience for trick-or-treaters.

While Ontario is set to experience a relatively mild fall, other parts of Canada might face different weather patterns. The Prairies and British Columbia are predicted to receive wet conditions around Thanksgiving, with this trend likely continuing into late October.

The Atlantic Coast and central provinces are forecasted to see warmer-than-average temperatures with increased precipitation extending westward.

As always, weather patterns can change, so it’s wise to visit the Farmers’ Almanac for up-to-date forecasts.
