Weather in Kristiansand in January

The month to avoid. January is the month most people should skip in Kristiansand. Highs sit at 3.9 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 12 of 12 — near the bottom of Kristiansand's year. July is the month that works, and the swing between the two is 53 points, which is a different holiday rather than a slightly better one.

Rain on 18 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 3.9 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 nights fall below freezing; the day barely swings — 2.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 10.2 °C and the coldest night fell to -8.8 °C, and the wettest single day dropped 40 mm — roughly 31% of the month's rain in one day.

January is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest January on record still delivered 267 mm against 38 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 130 mm average is a reasonable planning figure, not a promise.

Wind sits around 18.1 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 89%, which at 3.9 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How January sits in the year

Temperatures hold steady either side: 5.4 °C in December, 3.9 here, 3.1 in February. Nothing about the timing within the month matters much.

Daylight in January

January sits at the dark end of Kristiansand's year — 7.1 hours of daylight against 18.2 at midsummer, gaining 1.6 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 6.4 °C in January — too cold to swim without a wetsuit. The sea peaks at 16.9 °C in August and bottoms out at 5.3 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Kristiansand versus nearby

If Kristiansand is one option among several, the nearby comparison is worth making. Stavanger is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Gothenburg is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: January is a compromise. July is 53 points better and is what Kristiansand is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
