First Fall Frost of 2022

 It took awhile, but on October 23rd the Blatchford station finally recorded its first frost of the fall:

And it wasn't just the big city. The Stony Plain station also held out until the 23rd for frost:

Stony Plain had a few days earlier in October which were below 1°C, but Blatchford didn't drop below 1.3°C until the 23rd.

New Records

Blatchford's previous record for latest first-frost-of-fall had been October 21st, 1975, but 2022 beats that with October 23rd.

Stony Plain's previous record for latest first-frost-of-fall had been October 9th, in 2020 and 1979. 2022's October 23rd beats that by 2 weeks.

Frost-Free Days

So Blatchford's first fall frost was record-breakingly late on October 23rd, and the final frost of spring was a little late on May 10th.

With those two together 2022 had 166 frost-free days. Our average is around 144, so 166 is a lot, but it's not a record. Recently 2020 had 173, 2011 had 174, and 1980 has the record with 185.

The Neighbourhood

Around the neighbourhood the airport's first frost was back on September 20th, and Campsie's was September 10th.

On average Blatchford's frost-free season is about 1 month longer than the airport's, but in 2022 it was 166 days vs. 110 days.    

Across Canada

For some Canada-wide context, while a first-fall-frost on October 23rd is extremely late for Edmonton, it is right around the average for Montréal, Halifax & St. John's.
