Canada is bracing for an extreme cold front after a staggering temperature of -53°C was recorded in the Yukon. This represents the coldest temperature seen this early in the year in three decades. The reading came from Braeburn, Yukon, on Wednesday, December 12, 2025.
Yukon Temperature Records
This remarkable cold spell marks a significant weather event. The last time temperatures dipped this low in December was on December 5, 1995, when Ross River also registered -53°C. In addition, Whitehorse experienced its earliest -40°C temperature since 2006.
Impact of Arctic Air Movement
The frigid Arctic air is now shifting southward, beginning its journey over the Prairies on Friday. As it progresses, it is predicted to reach Ontario and Quebec by Sunday. This cold front could coincide with the development of a winter storm targeting Atlantic Canada by Monday.
Weather Outlook
Expectations for the upcoming days indicate a plunge in temperatures across much of Canada. While the extreme cold won’t replicate the harsh conditions faced in the Yukon, regions across the country will still experience unusually low temperatures for mid-December.
- -53°C recorded in Braeburn, Yukon on December 12, 2025.
- Earliest recorded -40°C in Whitehorse since 2006.
- Cold air set to impact the Prairies, Ontario, and Quebec.
- Potential for a significant winter storm in Atlantic Canada next week.
Understanding the dynamics of the polar vortex is essential, as it plays a critical role in these severe weather changes. Observers should remain vigilant as the cold continues to push south, bringing unprecedented winter conditions across the nation.
