Weather in Malmö in December

The month to avoid. Of the twelve, December is the one to avoid. Highs sit at 4.4 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

December ranks 12 of 12 — near the bottom of Malmö's year. July is the month that works, and the swing between the two is 51 points, which is a different holiday rather than a slightly better one.

This is persistent light rain rather than storms: 15 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Layers, and a genuinely waterproof outer — at 4.4 °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: 8 nights fall below freezing; the day barely swings — 2.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 10.3 °C and the coldest night fell to -11.7 °C, and the wettest single day dropped 25 mm — roughly 38% of the month's rain in one day.

December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 92 mm against 33 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 65 mm average is a reasonable planning figure, not a promise.

Wind sits around 18.6 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 92%, which at 4.4 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How December sits in the year

The month is on the way down: 3.4 °C cooler than November, with January dropping another 1.8 °C. The first week and the last are not the same trip.

Daylight in December

December sits at the dark end of Malmö's year — 7.1 hours of daylight against 17.5 at midsummer, losing 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

Despite being inland, the year stays fairly even: 21.3 °C between the year's warmest afternoons and coldest nights.

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.

December in Malmö versus nearby

If Malmö is one option among several, the nearby comparison is worth making. Århus is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Gothenburg is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: December is a compromise. July is 51 points better and is what Malmö is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
