2022 Year-in-Review Part 2: Precipitation

Are you ready for our 2022 Year-in-Review Part 2: Precipitation! We will take a look at Edmonton, and other big cities across Canada.
Sometimes the dashboards in these posts will become corrupted, and so if you are reading this in the future and things no longer make sense the original charts are here:
 
Edmonton averages 435mm of combined precipitation (rain + snow) per year. 

In 2022 Stony Plain was a little high with 468mm, the airport was just a little low with 419mm, and Blatchford had 390mm (that's up from 266mm in 2021).

Of all of the stations in the Edmonton area Stony Plain's 468mm was the highest, while Villeneuve was the lowest with 340mm.

On a monthly basis January-April were average, May was low, June was high, July-October were a little low, November was high, and December was average.

 

Big Storms
Our peak rain season is mid-May through mid-August.

The big storm for 2022 was on June 14th with 57mm in Stony Plain, 49mm at the airport, and 41mm at Blatchford. 

For large~ish 10mm storms Blatchford had 8, the International had 11, and Stony Plain had 12.




Precipitation Across Canada
For cities across Canada the total precipitation ranged from Saskatoon just above 200mm up to St. John's near 1700mm. Edmonton & Calgary were very close around 400mm.

Winnipeg is the real standout here this year, with 766mm as its #1 most precipitation on record.

The rest of the cities are pretty typical, although Montréal & St. John's were a little high, while Toronto and Vancouver were a little low.

 

Big Storms Across Canada
These festive-looking charts show the biggest storms of the year.

St. John's had the biggest single day, with 80.6mm on September 11th. Halifax had 67mm on June 9th and September 23rd. Winnipeg had 59mm on August 15th and Ottawa had 58cm on August 8th.

Halifax & St. John's were the winners for the most big storms, each with 9 40mm+ days. Winnipeg and Ottawa each had 2. Edmonton, Regina & Montréal all had 1.

That's the end of Part 2 of our 2022 Year-in-Review. In Part 3 we will take a look at snow.
