August starts with a divided pattern across Canada
We’ll kick off the month with a divided pattern draped across the country.
A brief period of cooler weather is settling into place across much of Eastern Canada to start August. Meanwhile, warmer-than-normal temperatures will dominate areas from British Columbia all the way through northwestern Ontario.

Early August will also see a decent amount of rainfall pushing into portions of British Columbia and Alberta. Some sporadic rain could even fall across parts of Saskatchewan and Manitoba where wildfires are currently contributing to poor air quality for large portions of the country.
The eastern cooldown won’t last long. We’ll see above-seasonal temperatures quickly return to Ontario, Quebec, and Atlantic Canada as we enter the second week of the month.
