Jan/Feb 1893 could be on that list too.

Agassiz recorded a high of -16.7c on January 30th, 1893 and -19.4c on February 2nd, 1893.

Jan 1909 was basically just as cold as well. The 7th/8th/9th had highs of -18.9c, -20.6c and -18.9c in Agassiz

Ya, I had forgotten about 1893 (was thinking of extreme daily lows), and it is the in the running for the coldest on record. It was by far the two coldest nights on record at Agassiz (-23.3 and -24.4). 1909 was crazy too, although it seems that Agassiz was a bit of an anomaly. Still between 1893 and 1909, that accounts for 6 of the 7 nights on record which hit -20C. The only other day being Dec 28, 1968.

It's interesting how the LOW and the HIGH were both -20.6C on Jan 8, 1909! And it snowed 12cm! On the coldest day ever recorded at Agassiz! Only 10 km away to the west there was just a trace amount of snow, and much warmer temperatures (high of -14.4C).

In the interior, the 1893 and 1909 nights were cold, but nothing compared to 1950 and 1968/69. The daytime temperatures were just as extreme, however. For Kamloops, Jan 30, 1893 and Dec 30, 1968 are tied for the coldest low on record (-28.9C). Dec 29. 1968 is the next coldest at -27.8C followed by Jan 10, 1909 at -27.2C. Jan 1911 and Jan 1950 were also very cold with highs of -26.7C.

Since records began in Penticton in 1907 there have been just 5 days at or below -20C (2 in 1909, 1 in 1964, and 2 in 1968), the coldest being -22.2C on Dec 29, 1968.

Looks like Agassiz dropped to -20c on Jan 21, 1943 as well. That was another all time great arctic blast.

Across the south coast, temps plunged below freezing on the 16th, followed a snowstorm on the 18/19/20th (50-75cm fell in the valley) while temps remained well below freezing. Another reinforcing shot of arctic air followed in the coming days, with a high of -10c at YVR on the 21st and a low of -16.1c on the 22nd.

Other extremes across the south coast during Jan 1943 included a high/low of -13.3c/-18.3c in Abbotsford, -13.9c/-20.0c in Agassiz and -17.8c/-20.6c in Hope.

Extremes in the interior included high/lows of -23.9c/-32.8c in Kamloops, -19.4c/-23.3c in Penticton and -28.9c/-42.8c in Williams Lake.

Totally different animal in northern BC. Atlin has records going back to the 1800s, and by FAR the coldest lows were set in December 1917. Same goes for the Yukon where this was by far the coldest month on record. Anyway, Top 5 coldest days on record in Atlin:

Jan 19, 1996 = -42.0C
Dec 27, 1917 = -41.7C
Dec 24, 1917 = -41.1C

BTW, of the 10 days that never climbed above -40C, 4 were in 1917, 5 were in 1996, and 1 in 1925.

Where did that warning come from? Nobody was talking about any significant winds. The secret mind of Environment Canada revealed.

Wow...looks like a strong El Nino pattern.

Keep chins up, longer range forecasts can change overnight, and with the la nina and “ No blob” bias it wont take much for a Arctic blast to sneak in. This weather has been just seasonal so far
