As of 11AM on October 10th Blatchford will have recorded 725.4mm of precipitation in 2026.
That's a new record! It beats 724.5mm from 1900.
(for the completists out there, Stony Plain got to 731.9mm in 1980, so we've still got that to aim for, possibly this weekend.)
I use data from Environment Canada, but if you look at their total it's only around 708mm. Why the difference? Well, they declare a day "missing" if any of its hourly data is missing. So they count a day like August 4 (and several others) as 0mm, even though their actual station actually recorded 5.6mm. I think that's weird, and it reduces their total by around 15mm.
So how did we break the record?
It was basically all June & July.
They are normally our rainy months, but in 2026 they were the 2nd & 3rd rainiest months ever recorded. In an entire year we average ~430mm, and they dropped 536.5mm in 2 months.

The Other Big Years
- 1901's 699mm had a big July (the biggest) & September.
- 1900's 724.8mm didn't have any huge months, but was above average from January through October.
- 1980's 731.9mm in Stony Plain had a big June-August, and December

Around Town
2026 was a somewhat strange year, with historically huge gaps between stations.
Everybody is above average, but Blatchford has 150mm more than Stony Plain, and 225mm more than the airport.
The stations won't always match, but they're never that far apart.
For the rest of the year we average around another 50mm. And yes, snow will count towards the total precipitation.
