December 2025 stats from my house: Maximum Temperature: 24.6F Minimum Temperature: -44F Average Temperature: -22.1F Snowfall: 24” Consecutive Days Below 0F: 28 (Still going into January 2026)

I think there’s a decent shot at PAFA recording -50s by sometime Sunday. We’re already holding steady in the low to mid -40s with 850mb temps cooling another 5-10° between now and then 👀

Fairbanks, AK, finishes December 2025 with a monthly temperature departure of 18.2F below normal. The average high temp was -14.5F and the average low temp was -31.1F. This makes it the 8th coldest December on record (1904-present) and the coldest since 1980. @alaskawx.bsky.social

Fun forecast for the airport from NWS Fairbanks

A couple of Fairbanks area climate site daily temps this month. Note there are several days when the high temperature at the airport is lower than the low temperature at UAF West Ridge. This is common in moderate to strong inversion situations. #akwx @leahwrenn.bsky.social @themattphelps.bsky.social

Sitting right about -44F to -45F this morning in Goldstream

If Fairbanks, AK, they have spent more hours in 2025 below 0F than above 60F; more hours below -20 than above 70F; more hours below -35 than above 75F; and twice as many hours below -40F than above 80F. @alaskawx.bsky.social

Seems like the ice fog is redeveloping pretty fast around Fairbanks tonight

Fairbanks: day after day after day in the -40Fs Juneau: nearly 4 feet of new snow Anchorage: NO COMPLAINTS ALLOWED

Today is the 5th day of December where Fairbanks had a high temp of -35F or colder. The last time a December had more such days was in December 1975. @alaskawx.bsky.social

Ok

On today’s episode of absolutely not gonna happen, enjoy this model showing -66F in Fairbanks next week lol not a forecast and not gonna happen

Here are a few back of the napkin stats for cold in Alaska this month. @alaskawx.bsky.social Coldest since 2010: Anchorage, Talkeetna, Homer, King Salmon, McGrath Coldest since 1980: Fairbanks, Bettles, Eagle, Delta Junction Coldest since 1964: Juneau

Lots of aurora filling the sky tonight

I hit the jackpot on eBay this month (got 2 of each style new in box)

My weather station temperature doesn’t go lower than -40F, but this old style thermometer is probably pretty close with -43F or so

-65F windchill at the Fairbanks Airport a bit ago

FAIRBANKS AK Dec 28 Climate: High: -43 Low: -48 Precip: 0.0" Snow: 0.0" Snow Depth: 18" Link

It’s a good morning for ice cream

Good news Fairbanks: with the airport currently sitting at -48F/-44C, the lowest temperatures in North America right now (Sunday morning) are right outside your window. So get out and carpe that diem. #akwx #AlaskaSky

It's been a warm/cold last 7 days, depending on where you live. 🥵🥶

A 110°F day in Phoenix in July is closer to the freezing point than Fairbanks is right now. @alaskawx.bsky.social

The cold snap in Alaska and the Yukon is now into week four and will continue for days. The latest from the Alaska and Arctic Climate newsletter provides some background on long duration cold events in northwest North America. #akwx #ytwx #Arctic #Climate alaskaclimate.substack.com/p/ongoing-co...

That’s fun

Fairbanks airport has not been above -40F/C Saturday afternoon and we're starting to develop real ice fog (not the "freezing fog" slop). #akwx #cold #Winter2026 @leahwrenn.bsky.social @coyotetrail.bsky.social @themattphelps.bsky.social @carrieinfbx.bsky.social

Ice fog time 😎

Perfect

High temperatures (ºF) in and around Alaska on Friday.This was the 23rd consecutive day colder than normal for the state overall. Colder across the North Slope and Bering Strait region. Slight moderation in Southcentral. #akwx #weather @climatologist49.bsky.social

Nice

Fairbanks airport: Friday (Dec 26) is the 23rd consecutive day with a low temperatures of -15F (-26.1C) or lower. Current forecasts show no major change in the wx pattern for the next two weeks, so this could end up into the top five longest runs. #akwx #Climate #cold @climateguyw.bsky.social

Christmas Creamer’s Field walk as is tradition 🤠🎄

Fairbanks area temperatures Christmas 2025 around 9am AKST. Ranging from -6F higher at up Goldmine Trail to -29F at the Airport and Goldstream Creek. #akwx @themattphelps.bsky.social

Fairbanks had its snowiest Christmas Eve on record today ❄️ Source: NWS Fairbanks

This has been the perfect December. Well below normal temperatures and above normal snowfall.

Hey that’s me

Holding steady at -4F this afternoon, my 20 day below 0F streak just might survive this system

The Juneau Intl Airport had consecutive -10F low temperatures for the first time in 50 years. @alaskawx.bsky.social @alaska.bsky.social 🥳

Today is day 20 of the Alaska cold snap. While it feels long, it has a ways to go to be noteworthy. That said, there is no end in sight to the current cold snap. It could easily last another 2+ weeks. Here are the lengths the longest cold snap for recent seasons (statewide). @alaskawx.bsky.social

Statewide temperature departure from normal yesterday in Alaska using station data. @alaskawx.bsky.social

Today will be the 20th straight day below 0F at my house. Warmup overnight and tomorrow with snow, then back to the freezer we go. ❄️

As I was finishing up at work this evening, there was a low fog that rolled in. As soon as it hit, it immediately felt 10° colder. Chilly evening at FAI

Just pulling into the airport for work, too bad car thermometers don’t read colder than -40

It’s 300 hours out and not going to happen, but it’s funny to see the 12z GFS show -60 for Fairbanks right after new years lol

That aurora substorm a bit ago was absolutely nuts

Solar noon from UAF Current temp: -36F

That seems suboptimal

Squared tires and what feels like the coldest morning of the winter so far at my house

Fairly strong temperature inversion in Fairbanks-land to ring in the Solstice. Low spots around 40 below while above 1500 feet MSL temperature near or above -10F. #akwx #Winter2026 @themattphelps.bsky.social @jenniferschell16.bsky.social @bikewritedave.bsky.social @phrozen.com

Today is the 7th day this month where Fairbanks, AK, has dropped to -35F or lower. Only 1 December since 1982 had more days (12 in 2012). @alaskawx.bsky.social

Balmy -30F this afternoon
