Few would've guessed after such a mild December, but this winter in Helsinki is turning out to be quite a 'special one' under current climatological standards.

It has been freezing 'permanently' for 29 days.

🧵(1/2)
Currently (counting today), we're at 29 consecutive ice days at Helsinki Kaisaniemi.

Based on today's 00z runs, I suspect the streak might be broken early next week, likely giving us the longest such streak since 2011.

If it wasn't for those 2-3 days mid January...

The January average of atmospheric CO2 at Mauna Loa was 428.6 ppm; that's 2.0 ppm higher than last year, fortunately not as fast a growth rate as we've often seen in recent years.

Also, climate ‘skeptics’ continuously told me that electric vehicles don’t work in the cold…

Yet, we drove hundreds of kms throughout Lapland in these kind of temperatures, without a problem.
Nice to see the consistent temperature inversion driving from Muonio (at the foot of the hill) to Olos, on the hill, where we’re currently staying. 🤓

This evening: -26°C in Muonio, -19°C in Olos.

Horizontal distance, 4km. Elevation difference: ~140 m

Tuore raportti AMOC-kiertoliikkeen keikahduspisteen vaikutuksista kehottaa tehostamaan ilmastonmuutoksen hillitsemistä, seurantaa ja varautumista.

Raporttiin on koostettu tieteellinen tieto AMOCin mahdollisen romahduksen vaikutuksista Pohjoismaissa.

Presented today.

The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the impacts of potential Atlantic Meridional Overturning Circulation (AMOC) collapse and provides recommendations for policy actions.

🌊 the report “A Nordic Perspective on AMOC Tipping” is out now.

📄 pub.norden.org/temanord2026...

The main message: weakening of the Atlantic overturning circulation is not just a theoretical risk. It is a real climate security issue for Northern Europe.

Europe had its coldest January in 16 years. Historically, it would have been considered a warm January (pre-1990).

Ice skating on the street: severe freezing rain made it possible in northeastern parts of the Netherlands earlier today.

Pret, vallen, opstaan, pijn en een beleving die je niet snel vergeet!

Diamond dust (snowfall during clear-sky conditions) was often visible during the <-20°C mornings in Southern Finland last week.

The worst of the cold has now subsided in the capital region, but the weather remains well below average in the upcoming period.

The sea ice conditions between Suomenlinna and Helsinki last Friday.👇🏼

Absolutely stunning views! 🌅❄️

The majority of the Gulf of Finland now has a sea ice cover. The Bothnian Bay is already fully frozen.

The cold weather is projected to continue.

Helsinki saw its coldest January since 2016 with a mean temperature of -7.4°C.

January is soon in the books, and what an exceptionally cold month it has been in northern Fennoscandia!

The monthly mean temperature in Sodankylä Tähtelä will be -21.2 °C. This means coldest January since 1987 and 5th coldest overall.
January 31, 2026 at 11:35 AM
Extremely cold morning in the capital region. Almost -25°C in Northern Helsinki!
January 30, 2026 at 6:32 AM
Substantial ice cover in the Gulf of Finland and Bothnian Bay already.

And the cold is projected to continue, and even intensify, in upcoming days. How far will it freeze?

Aurora borealis over Amsterdam (!), the Netherlands, last night.

G4 (Severe) Geomagnetic Storm caused widespread and bright northern lights, even at lower latitudes.

Green curtains were even visible with the bare eye.
