Bubbles showing December Rain
Bubbles showing December Rain
This morning is cold & snowy, but yesterday the airport got 2.7mm of rain. And that's the airport's 3rd rainy day so far in December.
2024 also had 3 rainy December days, with the latest on the 21st.
A lot of Decembers will get at least 1. #yegwx #yeg

...and that brings us to the end of our look back at November 2025 weather in Edmonton.
All of these charts are interactive dashboards with data for 17 Canadian cities, accessible at:
edmontonweathernerdery.blogspot.com/2025/12/nove...
...as for December...it's winter.
We do still average about 10 days with Highs above 0°C.
About half of the time December will hit -25°C, but since 1990 there have been 6 Decembers which didn't hit -20°C (including 2019 & 2023).
And December averages 16cm of snow.
public.tableau.com/shared/KHYYZ...
...a bunch of cities saw their snowdepths spike in November.
Dawson City, Calgary, Ottawa & Quebec City all got above 10cm, and Moncton got to 28cm.
public.tableau.com/shared/TPYR4...
...we often start to see lasting snow in the first week of November.
2025 waited until the 28th, and it's still pretty low.
2024 was November 22nd, and 2023 was December 3rd.
But who knows what the winter of 2025-2026 really has in store for us?
public.tableau.com/shared/PHPR2...
...this one is pretty busy, but it gives a sense of the snow season for all these cities.
Edmonton, Calgary & Dawson city all get started early.
And unsurprisingly, Vancouver, Victoria & Kelowna get started late.
public.tableau.com/shared/YS75T...
...historically, our first snow has been around the middle of October. That's for the airport and Blatchford, going back to the 1880s.
In 2025 our first snow wasn't until November 7th, and 2021-2025 were all pretty late.
public.tableau.com/shared/JM4BN...
...these are the cities with snowfall so far (although many cities, like Saskatoon, Regina & Winnipeg do not record snowfall).
Calgary was the only one to record any before November.
But by the end of November Calgary, Ottawa & Montréal have all had over 25cm.
public.tableau.com/shared/TQC43...
...in November we average 20cm of snow, and in 2025 we got 12cm.
We average 8 snow days, and the airport got 5.
public.tableau.com/shared/T4J2F...
...for big November storms:
St. John's had 5 days from 25-37mm
Victoria had 31mm
Halifax had 28mm
For Edmonton the biggest was 6mm on the 1st.
public.tableau.com/shared/WB9YD...
...these are the precipitation totals for 2025 across the country.
St. John's & Quebec City are way out ahead with around 1100mm.
The rest of eastern & central Canada range from 700-900mm.
The west is below 500mm, except for Vancouver at 774mm.
public.tableau.com/shared/KC7NT...
...by the end of November we average around 416mm of precipitation for the year.
2025 has had a really low September, July, April & February, so it's below average.
The airport and Campsie are at 376mm.
Stony Plain is down at 296mm, and Blatchford has 286mm.
public.tableau.com/views/Edmont...
...November's precipitation included 4 rainy days: the 1st, 6th, 13th & 23rd.
Even though we think of November as a winter month, most Novembers get a few days with rain.
public.tableau.com/shared/JDHBS...
...in November we average 20mm of precipitation.
Blatchford got close with 16.5mm, the airport got 14.9mm, and Stony Plain got 12.9mm.
public.tableau.com/shared/3SN8Y...
...with 1 month left, 2025's average temperature is top-5 in Dawson City, Kelowna, Edmonton & St. John's, and top-10 in Calgary & Charlottetown.
public.tableau.com/shared/M3SZ9...
...with a month left in 2025 its average temperature is currently Edmonton's 5th warmest overall, at 2.4°C above the 20th century average.
The Highs are actually our 4th warmest, while Lows are 5th, and combined they rank as 5th.
public.tableau.com/shared/MSY83...
...across the country November was cooler than the 20th century average in Ontario & Quebec (and Moncton), and warmer everywhere else.
That ranged from Dawson City with an average High 4.8°C above its 20th century average, to Ottawa at -1.5°C below theirs.
public.tableau.com/shared/P6BBF...
...November 2025 gets a medium orange bubble here, because it was fairly warm.
The average High of 3.1°C was 2.7°C warmer than the 20th century average.
The average Low of -6°C was 2.5°C warmer.
So far February is 2025's only blue month.
public.tableau.com/shared/FC686...
...so we narrowly missed a -20°C with the 29th's -19.3°C.
But in November getting all of the way to -20°C is not that common.
2010-2014 had a bunch of early deepfreezes, including a -29.8°C in 2014.
But since 2014, only November 2023 has crossed the -20°C mark.
public.tableau.com/shared/SPN7G...
...November's Lows were above average for most of the month, before cooling off near the end.
The 10th's Low of 2.9°C was close to 1895's record of 3.3°C, but other than that they were pretty typical.
The 29th's -19.3°C got us really close to our first -20°C.
public.tableau.com/shared/3PCJZ...
...November averages around 18 Highs above-freezing, and 2025 had 24 of them.
It also averages 2 Highs below 10°C, and this year we got 1.
public.tableau.com/shared/KJB2P...
...November was pretty mild for most of the month, but it did cool off for the final week.
Overall 23 Highs were above average, and 7 were below.
Nothing was close to a record, or even to the top or bottom of our ranges.
public.tableau.com/shared/R5RJY...
...November is one of the months where our average temperatures haven't changed too much over the past century.
But November 2025 was warmish. The average High of 3.3°C was our 44th warmest, and average Low of -6°C was 43rd.
That's just a little below 2023 & 2021.
public.tableau.com/shared/RHWKM...
Somehow it's December already, which means that it's time for our big look back at Edmonton weather for November 2025.

line chart of 2025 lows
heatmap of november lows 2000-2025
heatmap of november lows 2000-2025 with -15 highlighted
So November 25th was our first -10°C of the winter, and November 28th was our first -15°C. The last one that we had was back on March 14th. #yegwx #yeg
In November we average around 4 -15°C Lows, although sometimes (2023, 2016, 2009, 2008...) we don't get any.
public.tableau.com/shared/HZFHT...
It's kind of funny because in 1998 Blatchford only got 5.2mm (which is 5.2cm of snow), but the airport got 10.8cm (not sure why the number isn't showing up here.
public.tableau.com/shared/ZWC55...
2010-2025 snowdepths
1995-2009 snowdepths
So it looks like November 27th will be the start of Edmonton's "lasting" snow for 2025-2026. #yegwx #yeg
That's pretty late.
Recently 2023 made it to December 4th.
And going a bit further back 2008, 2007, 2005, 2004, 2002 &1997 all held out a little bit longer.
public.tableau.com/shared/NTHQ5...
...from April 1st to November 24th we went 239 days in-a-row above -10°C.
That's pretty typical, although that number has crept up from ~200 days a century ago.
The big standout is 2016 which went 278 days, from March 1st to December 3rd.
...by the end of November we average around 12 Lows of -10°C.
Recent high years like 2017 & 2012 got to 18, while there are also low years like 2023, 2016 & 2009 at or near 0.
public.tableau.com/shared/C2PQJ...
Low temperatures for 2025
November Lows since 1995
November Lows since 1995 with -10C days highlighted
So November 25th was Edmonton's first official -10°C of the winter. #yegwx #yeg
It's the first time that we've been down there since back on March 30th.
That's pretty late for a first -10°C, although 2023 got to November 30th, and 2016 & 2009 made it to December.
