September 15th will be the airport's first frost, with a Low around -1.4°C this morning. That's a little later than its average of September 10th. #yegwx #yeg (Stony Plain and Blatchford have stayed on the positive side so far)

...around the Edmonton region the story is a bit different. For the stations that have long histories the average first frosts are: Blatchford - September 30 Stony Plain - September 25 The airport - September 10 Campsie (100km NW) - September 5 public.tableau.com/shared/JZ598...

Around the neighbourhood Campsie (100km NW) did get down to -2.3C this morning. But the airport was just 0.9C, Stony Plain was 1.6C, and Blatchford was 4.2C.

People keep saying the f-word. At Blatchford, the average date of the first frost is September 30th. But the last time that we had September frost was 2019. And the last frosts this early in the month were 2018 & 2014. #yegwx #yeg public.tableau.com/views/Edmont...

For the Labour Day weekend Edmonton's average High is 20°C, and average Low is 8.9°C. #yegwx #yeg Recently 2022, 2024 & 2025 all threw heatwaves at us, with 2 or 3 days above 30°C, including Highs as hot at 33.8°C. The last Labour Day frost was back in 1992. public.tableau.com/shared/8Q5YQ...

In September we average around 32mm of precipitation. On September 3rd we got 10~15mm depending on the station. That pushed Blatchford's total for 2026 up to 711.7mm, which is now just 13.1mm shy of its all-time record of 724.8mm from 1900. #yegwx #yeg public.tableau.com/shared/G39CQ...

Somehow it's the end of August already, and we finished off the summer on a pretty quiet note. Let's take our big look back at Edmonton weather for the past month. #yegwx #yeg edmontonweathernerdery.blogspot.com/2026/08/augu...

August 2026 Review

Weather history for Edmonton Alberta, from a year-round active-commuter. Trends and records for the northernmost city of 1M people in North America.

edmontonweathernerdery.blogspot.com

August 13th's rain pushes the total for 2026 up to 700.4mm. That's now Blatchford's 2nd biggest year on record, passing 1901's 699m. #yegwx #yeg 1st place 1900 is an inch away with 724.8mm. (if we want to count Stony Plain, it got to 731.9mm in 1980) public.tableau.com/shared/D86H3...

With yesterday's 1.8mm and today's 0.8mm the total for 2026 should now be 699.1mm. That will take over the 2nd place spot from 1901. #yegwx #yeg (we're about an inch away from 1st place 1900)

After the ridiculousness of June & July it feels like someone has turned off the taps. But August has gotten a respectable 36.8mm so far. Blatchford's 2026 total is now up to 696.5mm. That's just 2.5mm from catching 2nd place 1901's 699mm. #yegwx #yeg public.tableau.com/shared/PYYDN...

For anyone curious about yesterday, downtown had 2 nice little storms: one around 3PM, and another around 5:30PM. Blatchford recorded 1.8mm for the first one, but 0mm for the 2nd. So we currently sit at 0.7mm away from 2nd place.

There's a nice little downpour downtown right now. If that also reaches the blatchford station it could be enough to take the 2nd spot.

"Unprecedented" gets thrown around a lot, but let's talk about our latest unprecedented summer with a big look back at July 2026 Weather for Edmonton. We've got lots of good stuff today... #yegwx #yeg edmontonweathernerdery.blogspot.com/2026/08/july...

In August we average around 50mm of precipitation. After 2 days Blatchford is almost halfway there, with 21.5mm. (on the chart it looks like practically nothing next to the massive June & July) #yegwx #yeg public.tableau.com/shared/QBBDG...

July 2026 Review

Weather history for Edmonton Alberta, from a year-round active-commuter. Trends and records for the northernmost city of 1M people in North America.

edmontonweathernerdery.blogspot.com

For the August Long Weekend Edmonton's average High is 24.2°C, and average Low is 13.2°C. In recent years 2025 & 2021 got to 30°C (and 2020, 2016 & 2015 got to 29°C). Our coldest recent one was 2002, with Highs way down at 9.6-13.1°C. #yegwx #yeg public.tableau.com/shared/7RCYY...

36 hours left to catch June 2026 (1.7mm) or July 1901 (15.3mm) Although whether or not those happen, the 535.6mm that we've gotten for June+July has already set a ridiculous new record. #yegwx #yeg public.tableau.com/shared/QHZNJ...

At 9PM tonight's total has climbed to 4mm. So July is still 1.6mm short of catching our ridiculous June. #yegwx #yeg

Everyone knows the drill by now... Today's 21mm pushed Blatchford's July total up to 263.5mm. That's our 3rd biggest month on record. It's 5.6mm short of our record-breaking June, and 19.2mm shy of 1901's all-time record. #yegwx #yeg public.tableau.com/shared/53JHP...

Apparently 3.2mm, so still 3rd place? #yegwx #yeg (the rain ended right on the hour, so there might be a little extra to carryover)

20mm for the record.

A potentially dangerous, severe weather day is once again on tap on Tuesday across central Alberta, including Edmonton, with several ingredients converging across the region. https://ow.ly/xh8L50ZtQHg

At 3PM the sun is out again, and Blatchford has recorded 21mm. So July 2026 now sits at 263.5mm. That's still 5.6mm short of our record-breaking June, and 19.2mm shy of 1901's all-time record. #yegwx #yeg

July 25th's storm pushed the July total up to 242.5mm, which is Blatchford's 3rd rainiest month on record. #yegwx #yeg The only months with more were 269.1mm last month, and 282.7mm in 1901. (and one more big storm could catch either of those) public.tableau.com/shared/XJ56W...

The rain is still going, but at 2PM it's been 16.2mm, which moves July 2026 up to 258.7mm. That's only our 3rd month to ever cross the 250mm mark. It's 10.4mm away from catching last month, and 24mm away from 1901's all-time record. #yegwx #yeg

Downtown has had two not-insignificant storms in the past hour. So I'm really curious how close this will push July to June's 269.1mm.

Back in December we got 59.9cm of snow, which is about 3x our average. Luckily January followed with a below-average 12.2cm, which gave us time to dig ourselves out. This summer we've now been hit with 2 3x months in a row... public.tableau.com/shared/G4MM8...

29.9mm total for the storm will push 2026 up to 634.7mm. That's still 5th overall. But its 7mm away from 4th place, & 15mm from 3rd. #yegwx #yeg

chris - sᴉɹɥɔ@yegwxnerdery.bsky.social · 2mo ago

It's still raining out there. #yegwx #yeg But as of 10PM Blatchford got another 15mm. That would push July close to 230mm. And 2026 overall will be around 620mm, which takes over as Blatchford's 5th most on record. public.tableau.com/shared/BPHF9...

Somehow it's both rainy & smoky? But this morning's rain pushed Blatchford's precipitation for 2026 up to 602.5mm. #yegwx #yeg That is Blatchford's 7th most on record. The last time Blatchford got to 600mm was 1978. The airport & Stony Plain got there in 1996... public.tableau.com/views/Edmont...
