Eastern Canada cooldown to flip from heat waves to hints of fall
A more comfortable pattern is on the horizon for much of Eastern Canada to round out August
It’s been a long, hot summer across Eastern Canada. Are you ready for a much-deserved cooldown?
A pattern flip on the horizon promises to send hints of fall sweeping across much of Ontario, Quebec, and Atlantic Canada over the next two weeks.
Not only will conditions cool off enough to open those windows, but some communities may even see low temperatures dip into the single digits.

Heat slips to hints of fall to round out August
It’s been a warm and muggy season so far across much of the region.
Many cities across Ontario, Quebec, and Atlantic Canada have seen 10-20+ days at or above 30°C so far this year.
As of the middle of August, Windsor has seen 28 days with high temperatures at or above 30 degrees. The count stands at 23 days in Toronto, 21 days in Ottawa, and an impressive tally of 5 days at or above 30°C over in St. John’s.
Many areas in Ontario and Quebec will add to that count this weekend, but a change is on the way by next week.

A hint of fall will push into northern Ontario on Sunday as high temperatures drop into the middle to upper teens. Some parts of the region could see overnight lows drop into the single digits.
Comfortable air will spread into eastern Ontario and southern Quebec as temperatures here will only reach the lower 20s. Readings north of Ottawa and Montreal will struggle to even hit the 20-degree mark. Communities outside the cities and their suburbs could easily see Monday morning lows in the single digits.
Folks across Atlantic Canada will see much cooler conditions dominate next week, with temperatures several degrees below seasonal for several days.
A brief warmup will arrive the following weekend before a more widespread cooldown arrives.
A strong cold front is expected to track across most of Eastern Canada, bringing a few days of much cooler temperatures for the final week of August. The comfortable, fall-like air may easily reach into southern Ontario and beyond well south of the border.
