Edmonton weather: has it really been THAT cool this summer?

Has it really been that cool of a summer in Edmonton? CTV News Edmonton's Josh Classen takes a look at the numbers.

There’s been a lot of chatter about the lack of heat this summer. But, that’s more perception than reality when you look at the numbers and there’s some recency bias playing into that perception.

Edmonton’s had some hot summers the past few years and the past ten days haven’t been overly warm in the city.

That said – we’re actually pretty close to the long-term averages for temperatures.

The month of May was three degrees warmer than average (and had three 30 C days).

June and July are almost exactly on par with the long-term averages and with one 30 C day in July bringing our annual total to four…THAT is right in line with “average”.

We HAVE had significantly fewer days with highs 25 C or hotter in July (than the recent past). We’re at nine, so far in July of 2025.

That’s the fewest since 2020 (when we had 10). We’ll likely get to a total of 11 or 12 by the end of this month, but that’s still a far cry from the TWENTY that we had in July of last year. July 2023 had 15, July 2022 had 17 and July 2021 had 21.

Looking at May, June AND July…we’ve had 22 days of 25+ C heat (on track for 24 or 25).

That would put us in line with 2024, but well behind 2023 (41 days) & 2021 (35 days).

2022 and 2020 both had fewer – 19 and 14 respectively.

As I mentioned earlier, we’ve had four 30 C days so far in 2025 (with the chance to get one or two more before the end of this month).

The long-term average for Edmonton in an entire year is four 30 C days.

For the months of May/June/July - 2023 had five. 2022 had two. 2020 had none.

But LAST year, we had ELEVEN 30 C days in May/June/July.

AND…in 2021…we had 19!

So…despite how it may “seem” like a cool summer – we’re actually on par with a “normal” summer when it comes to both average temperatures and the number of “hot” days.

It just might not feel that way because of the hot summers of the past few years and the lack of heat in the past week or two.
