Pakkanen: Talk About Freezing Finnish Weather

When autumn ends and the temperature dips below zero, you will hear one Finnish word everywhere: pakkanen (sub-zero weather, frost). While English speakers say "it's freezing" or "it's minus five", Finnish has a dedicated noun just for below-zero temperatures. Learning how to use this word makes your daily weather talk sound instant and natural.

After weeks of wet ground and grey skies, many Finns actually welcome the frost. If you have already read about Finnish words for slush like loska and räntä, you know that sub-zero cold means the messy slush finally freezes dry. Here is how to talk about the freeze like a local.

Pakkanen: The Magic Word for Minus Degrees

In Finnish, pakkanen is a noun. You do not usually use it like an English adjective. Instead, you say that frost "exists" outside.

The most common way to say it is freezing is:

Ulkona on pakkasta. (It is freezing outside / It is below zero outside.)

Notice the ending: pakkasta is in the partitive case because you are talking about an unspecified amount of cold weather.

When you want to state the exact temperature, Finnish uses a neat formula: luku (number) + astetta (degrees) + pakkasta (below zero).

Tänään on viisi astetta pakkasta. (Today it is minus five degrees.)
Huomenna on kymmenen astetta pakkasta. (Tomorrow it will be minus ten degrees.)

What about when the temperature is above zero? You simply swap pakkasta for lämmintä (warmth):

Tänään on kolme astetta lämmintä. (Today it is plus three degrees.)

You will also hear people say miinus viisi (minus five) in everyday speech, but viisi astetta pakkasta is the classic phrase you will hear on weather reports and at the bus stop.

Kylmä vs. Pakkanen: Don't Mix Them Up

A common beginner trap is confusing kylmä (cold) and pakkanen (frost / sub-zero weather).

Kylmä is an adjective. You use it to describe objects, feelings, or general temperature:

Tee on kylmää. (The tea is cold.)
Minulla on kylmä. (I am cold / literally: On me is cold.)
Tänään on kylmä päivä. (Today is a cold day.)

Pakkanen, on the other hand, only refers to air temperatures below 0°C (32°F). You cannot have a "pakkanen tea", and you cannot say "minulla on pakkanen".

Here is a quick cheat sheet for common cold-weather words:

nollakeli (zero-degree weather, hovering right around 0°C)
pikkupakkanen (light frost, around -1°C to -5°C)
tulipalopakkanen or paukkupakkanen (bitterly severe cold, the kind where wood "bangs" in the wall)

When the cold bites, you need warm clothes. A thick knitted wool sweater is called a villapaita, and a warm winter hat is a pipo.

Essential Cold Weather Words

Here are eight essential terms you can use throughout the Finnish winter:

Finnish	English	Example
pakkanen	sub-zero weather, frost	Talvella on paljon pakkasta. (In winter there is a lot of freezing weather.)
aste	degree	Mittarissa on kaksi astetta. (The thermometer shows two degrees.)
kylmä	cold	Täällä on tosi kylmä. (It is really cold in here.)
jää	ice	Järvessä on jo jäätä. (There is already ice on the lake.)
jäätyä	to freeze	Maa jäätyy marraskuussa. (The ground freezes in November.)
lämpömittari	thermometer	Mitä lämpömittari näyttää? (What does the thermometer show?)
pipo	beanie, winter hat	Muista laittaa pipo päähän! (Remember to put a beanie on your head!)
paukkupakkanen	cracking severe frost	Tammikuussa on usein paukkupakkanen. (In January there is often severe frost.)

How Finns Live with the Freeze

When the first pakkanen arrives in November or December, daily life changes in small, practical ways. Car owners plug their vehicles into outdoor electric poles to warm the engine with a lohkolämmitin (block heater). Cycling paths are gritted with small crushed stones to prevent slipping on black ice.

Finnish culture does not stop for sub-zero weather. Daycare children still play outside in snowsuits down to about -15°C. In fact, many Finnish parents wrap their babies in thermal sleeping bags to nap outside in prams during pikkupakkanen, believing the fresh, crisp air promotes sound sleep.

Small talk with neighbours or colleagues in the elevator often boils down to a quick check of the numbers: "Onpa kylmä!" (How cold it is!) followed by "Joo, mittari näyttää miinus kahdeksaa." (Yeah, the thermometer shows minus eight.)
