There's another new fall forecast that revealed when Canada's weather will turn cooler than normal.

Some provinces are expected to get "early snow" and chilly temperatures throughout the season.

Recently, the Old Farmer's Almanac put out the 2025 fall weather forecast for Canada.

It called for cooler-than-normal temperatures from southern Ontario to the Atlantic provinces, while the rest of the country gets near-to-above-normal warmth.

Also, most areas should get above-average precipitation, except for southern Ontario and southern B.C.

According to the Old Farmer's Almanac, B.C.'s weather for the fall will be warmer than normal, with near-average precipitation across southern parts of the province.

In September, the average temperature will be 15 C, which is 1 C above normal.

The month starts with sunny conditions, but then isolated showers move in at the end of the month.

In October, temperatures will be around 11 C, which is 2 C above average.

You can expect mostly sunny and warm conditions at the beginning of the month, followed by a mix of isolated showers and sunshine.

Cooler temperatures will pop up mid-month in B.C., but then it will be rainy and warm.

The fall season in the Prairies is forecast to be warmer and wetter than normal.

September will have temperatures around 12 C, which is 1 C above normal, and average precipitation.

The start of the month will feature isolated showers and cooler temperatures, but mid to late September will be warmer with thunderstorms and "very warm" days.

October will have an average temperature of 8 C, which is 2 C above normal.

You can expect a warm, sunny start to the month and some light rain mid-month.

Then, western parts of the region could get early snow flurries before the weather warms up again near the end of October.

According to the Old Farmer's Almanac, Ontario's weather for the fall will be cooler than normal, with above-normal precipitation in the north and below-normal precipitation in the south.

September is forecast to have an average temperature of 13 C, which is 2 C below normal, and above normal rainfall in the north but normal rainfall in the south.

You can expect thunderstorms and mild temperatures to start the month, but then it'll be chilly and rainy with just a few sunny breaks.
