July 2025 Review

It's time for our big look back at July 2025 weather in Edmonton. Was it unseasonably cold? Kind of, but also not really? Let's take a look...

The general consensus seems to be that July 2025 was pretty cool. 

The average High of 23.9°C was our 52nd warmest on record, and above 2023 & 2020. 

The average Low of 12°C was our 49th warmest, and the coldest since 2019. 

So it was cool, but not particularly cold.





High Temperatures

July started and ended warm, but was a little cool in the middle. We only had 13 Highs above the 30-year average, compared to 18 below. 

The hottest was 31.9°C on the 2nd & 8th. The coldest was 16.3°C, which was July 21st's 5th coldest High on record.

July averages 12 25°C Highs, and 2025 had 12.

 

And it averages 3 30°C Highs, and 2025 got 3. 

The coldest High was 16.3°C on the 21st, but 2023, 2022 & 2021 all had Highs below 15°C.





Hot Days So Far

By the end of July we've had 62 20°C Highs. That's around average, and more than 2024, 2022, 2020, 2019. 

We've had 25 Highs reach 25°C - less than 2023, 2021 & 2018, but more than a lot of years.

July 31st was our 6th 30°C High of the year, so far.

This is the 5th summer in-a-row (2021-2025) to get to 6 of them. That's only happened once before, in 1932-1936.



Low Temperatures

July's Lows were pretty chilly, with only 12 above-average and 19 below.

And 4 of those were the coldest in at least 30 years. The 15th's 5.6°C and 23rd's 6.1°C were both bottom-10 Lows for those days.

Our range of July Lows is pretty narrow, usually between 5-20°C.

2025 had 8 cool Lows between 5-10°C, when the average is only 4.



Warm & Cold Months

July 2025 was cooler than recent years, but still warmer than the 20th century average, so it gets another small orange bubble.

The average High of 23.9°C was 0.6°C warmer than the 20th century average, and the Low of 12°C was 1°C warmer.



Across Canada

July 2025 was not warm in Edmonton, but it was actually cool in Calgary, Saskatoon & Regina, with Highs around 2°C below their 20th century averages. The rest of the country's Highs were around 2°C warmer than theirs.

For 30°C days so far this summer central Canada is a little above average, while Saskatoon & Regina are pretty low.



Precipitation

July is typically our rainiest month, averaging 90mm.

In 2025 the airport got up to 102mm, while the other stations were below 40mm.

The big difference was that the airport got a 20mm storm on the 6th, and 17mm storms on the 19th & 20th.

Blatchford's biggest day was only 12.7mm on the 19th.

By the end of July we average around 290mm of precipitation for the year.

The airport is right on average, and the other stations are down around 230mm.

These are the precipitation totals for 2025 across the country.

Quebec City is at the top with 750mm, which is their 20th most on record.

Calgary's 375mm is well ahead of Edmonton's 220mm, and is their 17th most.

And Winnipeg's 126mm is another low year for them.

Across the country the biggest July storms were:

• Montréal with 81.6mm on the 13th
• Toronto with 48mm on the 20th
• Quebec City with a whole bunch (6) ~30mm days.

August

For August on average we have 25 Highs which reach 20°C, including ~10 above 25°C. About half of the time August hits 30°C.

Most Lows are 10~15°C, but half of the time August will have a night below 5°C.

And August is our 3rd rainiest month averaging 52mm.
