October 5th got to 20.7°C. #yegwx #yeg 20°C Highs aren't too uncommon in early October, but they start to get pretty rare after around the 10th. public.tableau.com/shared/6C65J...

Blatchford's first fall frost will be October 4th. #yegwx #yeg That's later than the average of September 30th, and it's the same day as 2025. Recently 2022 & 2023 set records, waiting until October 23rd & 22nd respectively. Our last September frost was 2019. public.tableau.com/shared/FP85M...

For anyone who is interested, the big September recap will need to wait until October 2nd, due to a roadtrip.

I forgot to do this yesterday, but for Summer 2026 Edmonton's Highs were its 15th warmest on record (2024, 2025, 2022 & 2021 were 1st through 4th respectively) and 1.7°C above the 20th century average. The Lows were 7th, and 2.6°C above average. #yegwx #yeg public.tableau.com/shared/ZFSRF...

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 22/09/2026

September 21st's High of 28°C will rank as the 4th warmest on record. 1967 was at the top, at 30.6°C. This morning's Low of around 8.6°C will probably rank 6th. #yegwx #yeg public.tableau.com/shared/WM7R6...

192

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 20/09/2026

Yesterday's High of 25.3°C was nowhere near the record of 29.4°C. But once we get past mid-September the 25°C days do become less common. A lot of years don't get any (2023, 2018-2018), while 2025 & 2022 each got 3, and 2014 got 5. #yegwx #yeg public.tableau.com/shared/MPFQC...

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 15/09/2026

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)

173

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 13/09/2026

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.

062

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 13/09/2026

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...

2103

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 04/09/2026

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...

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...

185

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 13/08/2026

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)

062

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 13/08/2026

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.

061

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 12/08/2026

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.

261

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 12/08/2026

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...

It's the first day back after a long weekend. Why not ease into work with some light weather nerdery:

042

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 03/08/2026

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...

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...

011

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 30/07/2026

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...

0103

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 29/07/2026

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

0146

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 29/07/2026

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)

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...

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 27/07/2026

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

161

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 27/07/2026

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

3101

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 27/07/2026

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.

210

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 27/07/2026

Just once it would be nice to be able to go a day or two without needing to update this.

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 26/07/2026

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...

122

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 26/07/2026

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...

3197

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 26/07/2026

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

198

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 26/07/2026

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...

284

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 21/07/2026

And because it won't stop raining, we've now passed 1978's 604.3mm and taken over the #6 spot.

052

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 21/07/2026

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...

131

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 20/07/2026

This morning's rain pushes July ever closer to the 200mm mark. Blatchford has only ever recorded 4 of those: July 1901, June 1914, July 1937, and...June 2026. #yegwx #yeg

July 18th was our 4th 30°C High of the year. #yegwx #yeg Historically 4 would have been plenty for us. But recently we've had our top 3 years with 14 in 2025, 16 in 2024 & 17 in 2021. And some of those happened pretty late into August & September... public.tableau.com/shared/SF7GW...

151

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 19/07/2026

Blatchford got at least another 30mm tonight, which will push its total for the year past 560mm . #yegwx #yeg That's more than any year since 1978. And it's the 8th most precipitation on record (and we've still got 5 and a bit months left...) public.tableau.com/shared/KMYW9...

1122

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 19/07/2026

The rain won't be over for awhile, but the first wave of the storm dumped 30mm on Stony Plain, 12mm on Blatchford, and 10mm on the airport.

041

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 18/07/2026

July 17th's High of 30.7°C was our warmest day of the year, and our 3rd 30°C High of 2026. #yegwx #yeg 30.7°C was our 11th warmest July 17th, and the Low of 17.8°C tied 1987 for 4th warmest. 2024 has both those records at 34°C & 19.1°C. public.tableau.com/shared/Y3RGC...

chris - sᴉɹɥɔ @yegwxnerdery.bsky.social · 17/07/2026

So we are right at the peak of our summer, and it's supposed to get hot. But these warm mornings will always be a bit of a surprise. Today's Low of around 17.7°C would be our 5th warmest for July 17th. #yegwx #yeg public.tableau.com/shared/Z9TB2...

Charts aren't updated yet, but Blatchford got another 40mm storm this morning. #yegwx #yeg That will be our 4th of the year (3 was already a record). July's total is now 139mm.
