After a slow start to the season, summer finally hit its stride in the month of July. Will the summer end strong or will fall come early? To look ahead to the month of August, please read on.
But first, here’s a look back at what we saw in Canada during the month of July.
Much of the country saw near-normal (indicated in white in the chart below) or warmer-than-normal temperatures (indicated in different shades of orange and red in the chart below). Most of northern Canada has been extremely warm and eastern Newfoundland has also been very warm, but at least we haven’t seen the widespread dangerous heat we saw last summer.

In July, below-normal temperatures were limited to areas from northern Ontario to Labrador. That’s in contrast to June, when cooler-than-normal temperatures dominated much of Canada.
The pattern for early August will resemble what we’ve seen over the past few weeks, but with a few notable differences.
Hot weather is expected to dominate from the southern prairies to Atlantic Canada. However, colder weather is expected across much of northern Canada, and the proximity of that cooler weather does pose a risk to the forecast. Cooler weather may push south at times and briefly dissipate the heat in southern areas.
We also expect British Columbia to return to the cooler pattern that dominated most of the summer before the heat wave that arrived in the last week of July.
As we progress into the second week of August, we expect the focus of the hottest weather to begin to shift to the west. This will bring closer to seasonal temperatures across Atlantic Canada with a few shots of cooler weather.

For Ontario and Quebec, we have the potential for a longer break from the heat through mid-August with a period of cooler weather that could last approximately 5-10 days. However, this will not signal an early end to the summer weather, as we expect hot weather to spread across the region again at times in late August and into September.
It looks like hot prairie weather will dominate mid-to-late August, especially in the southern parts of the region. However, we are likely to see some breaks from the heat at times.
Across British Columbia, periods of warmer weather are expected in mid-to-late August, but we don’t expect temperatures to get as high as we saw in the last week of July.
Summer isn’t quite over for northern Canada, but the overall pattern looks much cooler than what we saw in the first half of the season.
While August will bring a changeable pattern at times, here’s what we expect the final numbers to look like for the month as a whole.
For most of Canada, this means plenty of very warm weather is still ahead with widespread near-normal or above-normal temperatures expected for August.
However, with widespread below-normal temperatures biding their time across much of northern Canada, there will be some significant heat breaks and even the potential for quick shots of cooler weather to bring a hint of next season .
