November 2022 Review

It's time for our big look back at Edmonton's November 2022 weather. And after a warm summer and fall, things have taken a bit of a turn...

November 2022's average High of -2.1°C ranked as 107th warmest (or 36th coldest) since 1880. The average Low of -10.1°C was the 96th warmest (or 47th coldest). It was a below-average November, but still warmer than 2017, or 2012-2014.



High Temperatures
November started cold, got really cold, got a little warm, and then was really cold at the end. November 7-9 had our coldest Highs in the last 30 years. We end up with 12 Highs above average and 18 below.

In November we average about 18 Highs above freezing, and 2022 had 15. We also average around 8 Highs of 5°C or more, and 2022 only had 5. Sometimes November doesn't have any Highs below -5°C (like in 2021) but this year we had 9.



Low Temperatures
For November 2022's Lows the 7th-10th were the coldest that we had had in 30 years. Overall only 9 Lows were above average, compared to 21 below.

For 2016-2021 we didn't hit -20°C in November, but that 6-year streak ended with our first -20°C very early on November 9th. November only averages about 1 -20°C, and this year we had 3.



Cold Days So Far
For the past few winters we hadn't hit -20°C until December, and 2020 even held off until January 9th. So the 3 that we got this November were a little bit of a shock, but recently November 2014 & 2010 each had 5, and 2006 had 6.



November Temperatures
This compares the distribution of our November temperatures for the past few years. It got cold in 2022, but not as cold as 2014, 2013, 2011, 2010, 2006... It also didn't get very warm though, with the warmest High as 7.4°C on the 14th.



Warm & Cold Months
After as string of warm, orange bubbles going back to June, with November we finally get a blue bubble. November 2022's average High of -2.1°C was -2.5°C below the 20th century average. The average Low of -10.1°C was -1.7°C colder.



The Horserace
At the end of October 2022 ranked as Edmonton's 4th warmest year overal, but the cool November has pushed that down to the 8th spot. The Highs are the 14th warmest, and the Lows are the 7th.



Across Canada
For November across the country it was cold in Vancouver-Saskatoon, close to the 20th century average in Regina & Winnipeg, and warm further east.



Precipitation
In November we average 21mm of precipitation (rain + snow) For 2022 Blatchford & the Airport were a little above that with 27.2mm & 32.4mm respectively. Stony Plain was basically right on the average with 20mm.

November averages 9 days with precipitation. Stony Plain and the Airport were a little high with 11. Something has been wrong with Blatchford since August, because it's recording way too many days (but the amounts are small, so the totals aren't affected).

By the end of November we average around 420mm of precipitation for the year. Stony Plain has 455mm, the airport is at 419mm, and Blatchford is down at 376mm. For all of the local stations Stony Plain is the highest, and Campsie is the lowest at 320mm.



Precipitation Across Canada
This messy chart has 2022's precipitation for 11 cities. Saskatoon & Regina are at the bottom. Next Edmonton & Calgary are close at around 380mm. At the top Halifax is near 1300mm, and St. John's is close to 1600mm. Winnipeg is having a top-10 year.

For the big storms in November: - 42.8mm in St. John's on the 12th - 39.4mm in Montréal on the 11th - 35.8mm in Halifax on the 12th - 31.6mm in Vancouver on the 4th



Snow
The only local station recording snowfall is the airport. In November we average around 20cm, and in 2022 we got 31.8mm. That's the 9th highest November for the airport.



First Snow
The airport's first measureable snow for the winter of 2022-2023 was on November 1st. The average date is October 11, so we were a few weeks late this year.



Snowdepth
The airport, Stony Plain, Elk Island and Campsie are all measuring snowdepth this year. At the end of November we average about 10cm of snow on the ground. The airport & Elk Island are around 15cm, and Stony Plain & Campsie are around 9cm.

This is just a comparison of how our snowdepth builds up in the early part of the winter, for the past few years. So far 2022-2023 is typical enough.



Snow Across Canada
An ugly chart again, showing who has had snowfall so far. Calgary is at the top, and then Edmonton. Then St. John's, Montréal, Toronto and Ottawa are all bunched up. We won't have snow measurements for Regina, Saskatoon or Winnipeg this year.

For the big snowstorms so far Montréal had 11.4cm on November 16th, St. John's had 11cm on the 22nd, and Calgary had 10cm back on October 22nd.

For snowdepth Edmonton is at the top, and Winnipeg just jumped up to 7cm. Everyone else is either low, or reading nothing.

It's pretty typical for Edmonton to be the champion for long-term snow. In Ottawa, Montréal and St. John's it usually doesn't start building up for another month or so.



December
In December we average about 10 days with Highs above 0°C. For the Lows, since 1990 there have been 5 Decembers which didn't hit -20°C, and about half of the time December will hit -25°C. December averages 16cm of snow.
