November 2025 was very warm overall in Canada, with record-breaking averages in some places. However, southern Ontario and Quebec managed to get below average temperatures. Most of Ontario and Quebec also had more snowfall than normal. #wxtooter

Today was... even hotter than yesterday in Eastern Canada! 🥵

All-time records were set at several stations, and the all-time PEI record was shattered with 38.1° at Maple Plains!
36.7° in Badger, NL tied August record for NL and all-time record for the island. 38.6° in Miramichi is 0.8° below NB all-time record.

Here are some of the very hot temperatures recorded today in Eastern Canada... Up to 37.6°C in Miramichi, NB!
A few monthly records tied/broken, and tomorrow could be hotter locally! #wxtooter
July 2025 was a mixed bag in #Canada. Generally hotter than normal in the east, but slightly cooler in many regions. Northern Nunavut had the coldest anomalies, between 1° and 2°C below the 1991-2020 average. #wxtooter

Much of Alaska north and west of the Alaska Range came in with near to bit above normal temperatures in June. In contrast, southern areas were mostly near to below normal. At Bethel, this was the coolest June since 1985. At Kotzebue, this was the mildest June since 2019. @Climatologist49 @pat_wx

The Chukchi Sea (northwest of Alaska) at the end of May had the lowest open water area since 1999 (though only slightly lower than 2012). This was an outcome of persistent north to northeast winds aloft.
