I swear the Nordics get much more exceptional cold snaps compared to places in the U.S. with similar winter averages. Perhaps the more northern latitude helps that?
Yes, the latitude has an effect, but remember that January 1985 and 1987 were by far the coldest ever recorded, and it won't likely happen again in our lifetime, if ever at all.

Sounds like February 1936 in the Upper Midwest, where there places with as much as a 20 C negative deviation from the average for the month.

mostly latitude i think. the averages can be equally wild in alaska. btw: where's tom falcons 77 nowadays? too warm in the us, and too cold in europe i guess.

Also depends where in the Nordic area.
Just want to mention Tromsø (met.office) far up north with an all-time record low of -18.4C (avg high -2C midwinter), and that station has been recording for more than 100 years.

Also in 1985 the cold was heavily concentrated up north if we're talking the extreme cold. For example Linköping had -5.8C as high and -11.7C as low for January with extremes no more severe than -22.3C and every day climbing above -15C...

That's just a bit of a cold winter month. Even the first few weeks of this year were like that, and 2010 saw both Jan and Dec be even colder than Jan 1985 this far south.

He only posts if there's something to ***** about if it gets cold in January/February that'll be a guaranteed tom77falcons appearance.

Very good point, I suppose what I'm referring (colder cold snaps relative to average) is continental northern Sweden away from the coasts, Finland and perhaps inland Norway. I know Karasjok has seen some serious cold snaps, but that's probably perhaps the coldest spot in Scandinavia.

I always forget how far south in Scandinavia you are since 58 N is still a pretty northerly latitude but of course, the Nordics extend up to 71 N, and near 80 N if you count Svalbard.

The coldest night of the year typically falls to -1F here on average, but the range of the coldest night can go from -13F to +18F... it so much depends on what kind of air masses are in motion. It's the same with summer, they're also highly unpredictable. The warmest day of the year can swing from 78F to 93F...

Coldest night on average is about 38-40 F here, but has dropped as low as 27 F and also I'm sure we've had a winter where we didn't drop below 50 F all winter.


It can be pretty variable here too considering our low latitude, check out December 2010 and December 2015:

A 17 F (9.4 C) difference in mean temps.



Btw one interesting tidbit, your latitude (58 N) is exactly halfway between mine (26 N) and the North Pole (90 N).


Our summer maxes are quite constant though, almost always in the 95-98 F range.

I've spent a lot of time in Tumut and Batlow, and do have some experience with the weather in Canberra and Wagga Wagga. The weather is warmer, drier and sunnier than here, but the balance of high pressure, cold front and northerly system seemed similar.

I think Finland especially is prone to extreme cold because of Russia and Eurasia to the east whereas Sweden is a peninsula. Turku for example at 60'N has similar record lows as Sundsvall at 62'N. Not as true for Scandinavia.
