Copenhagen, Denmark
September 2019

September was a fantastic month in Saskatoon, with most of the month being quite a bit above average. It felt like a slightly cooler continuation of (an admittedly mild) August rather than a real fall month, aside from a few days in the middle and at the end. The lows in particular were quite a bit above average, with the first three and a half weeks of the month having an average low warmer than August. This was also our 5th month this year with a record high above 30C.

This was the stormiest September I've experienced, with several major thunderstorms throughout the month including one after the equinox, which I had never seen before.  Precipitation total was slightly above average and precipitation days well above average, though most of those days had very low amounts so it didn't feel like a rainy month at all. Sunshine stats will be out in a few days and I think it'll probably be around average.

We got a serious cold snap with a bunch of snow at the very end of the month which dragged the average temperatures down a bit, but overall it was by far the nicest month of the year relative to average. I doubt we'll top that in Oct/Nov/Dec. We also managed to avoid dropping below freezing despite more than 24 hours of snow and a couple of forecasted lows well below freezing, so that was pretty cool.

Stats:

Average high: 18.5C (normal: 18.3C)
Average low: 6.1C (normal: 4.5C)

Highest high: 31.2C (Sept 16th)
Highest low: 12.3C (Sept 17th)

Lowest high: 1.5C (Sept 30th)
Lowest low: 0.1C (Sept 28th)

Precipitation: 39.5mm (normal: 35.4mm)
Precipitation days: 17 (normal: 8.4)

Stable and somewhat warm month.

Average high: 74.7 (+3.1)
Average low:  54.4 (+2.4)
Mean:            64.6 (+2.8)

Precipitation: 3.01” (-0.37”, 89%)
Precipitation days: 9

Highest temp: 88 on the 22nd
Lowest temp: 48 (!) on several days
Highest low:  66 on the 11th
Lowest high: 63 on the 29th

•Warmest September record low ever—insane given how the month wasn’t much above average
•T-4th warmest low max on record

•Coolest September since 2014
•First September not to hit 90 since 2012

The beginning was cool but it ended with 13 straight above average days.

Here’s the month:


And the year:

Shittiest septmeber in terms of rain.. last year was 85/69 with 8 inches of rain, infinitely better than this crap!

Mean Max Temp: 87.6 +5.5 anomaly
Mean Min Temp: 66 + 4.3 anomaly ( ignore climate box it should be 66 not 66.1)
Mean Temp: 76.8 + 4.9 anomaly
Max Temp: 96
Min Temp: 50
Rainfall: Don't ask
Rank: 5th warmest September on Record, last year was 4th






Fun Fact: June was below average and this September was well above so it finished warmer than June!

Knowing your preferences for temps it is solely because of May and September and lack of snow. That and the drier  than normal summer. For me its atrocious because of the cold march and lower summer rainfall.

Tied for 9th hottest September on record. Warmest highs of the year. Nearly all the rain came from Tropical Storm Imelda Sept 17-20 (while I was on vacation).

Lowest max: 80F
Highest min: 73F
