Luxembourg in December, a city month with short days

In December Luxembourg shrinks down to its capital. The countryside goes quiet, the days are short and the weather won’t help, but the city has its liveliest weeks of the year. Go with that in mind and it’s a very good month for a short break, and an easy one to reach from Britain.

What’s the weather like in December?

Cold, damp and dark, in that order of importance for a visitor. MeteoLux’s normals give a 2.3°C (36°F) average, but what really defines the month is that none is wetter, at 89.5 mm, and none has less sunshine, 41.9 hours across thirty-one days. Fog turns up on 11.3 days on average, another high for the year, and black ice on 1.4. Snow is possible, though there are no official figures for snow days to back it up.

The extremes show how much it can vary. On 31 December 2022 Findel reached 15.7°C, and on 29 December 1976 it fell to −15.3°C. The full series is in Luxembourg weather.

The capital under the Winterlights

The reason to go in December is Winterlights, which the Ville de Luxembourg runs until 3 January 2027, with Christmas markets across several squares in the centre, concerts and shows. Each market has its own character, and I go through them one by one, with what to eat and drink, in Luxembourg Christmas markets.

On 6 December comes Kleeschen, St Nicholas, who in Luxembourg is the one bringing the children’s presents, with his sidekick the Houseker for anyone who’s misbehaved; the whole tradition is in Kleeschen, Luxembourg’s St Nicholas. At the Niklosmaart on Place de Paris there are days when children can find him in his cottage, “Dem Kleesche säin Haus”, according to Visit Luxembourg. And watch out for Monday 7 December 2026, when the Pfaffenthal lift stops from 9:00 for its monthly service.

Three winter trips outside the city

Visit Luxembourg makes a point of Advent not being just a city affair, and I agree. Echternach, the country’s oldest town, holds its Christmas market and lights up its abbey. Up north, Clervaux suggests a quiet walk around the castle, where The Family of Man stays open until 1 January 2027. And in the west, the Haut-Martelange slate museum hosts a Christmas market around its buildings. Neither Echternach nor Haut-Martelange had 2026 dates out by the end of September.

Mondorf-les-Bains, on the Moselle side of the country, repeats its market on Place des Villes Jumelées on the weekends of 4 to 6 and 11 to 13 December 2026.

The four dates that change opening hours

It’s worth having the calendar to hand. On 24 and 31 December shops can open until 18:00 at most, and banks close on the afternoon of the 24th. Friday the 25th, Christmas Day, is one of three days a year when the law bans shops from opening, bakeries, patisseries and a few food shops aside. Saturday the 26th, St Stephen’s Day, is also a bank holiday, so shops that open keep to holiday hours, 19:00 at the latest. Restaurants, bars, hotels and shops in stations and at the airport sit outside those rules, and the capital’s tourist office closes on the 25th. Each holiday is covered in Luxembourg public holidays.

Getting about when it’s dark by mid-afternoon

With so little daylight, I wouldn’t hire a car for a December trip based in the capital. Public transport has been free nationwide since 1 March 2020, visitors included, and the T1 tram runs from Findel airport into the centre and on to Kirchberg with no changes. After a market or a concert at the weekend, the City Night Bus keeps going until 3:30.

If you do drive north or into the Mullerthal, remember that you must have M+S or alpine-symbol tyres whenever the road has ice, snow or frost, and in December that can be any morning. Coming by train via Brussels or Paris instead, remember you’re entering the Schengen area, where the EES registers British passport holders on arrival, and that your GHIC covers state healthcare but not everything a travel insurance policy does.

When I’d go in December

The first two weeks. Luxembourg’s schools break up on 19 December 2026 and stay off until 3 January, and from then the city gets busier and hotels fill sooner. Two days are enough for markets, cathedral and museums; with three, I’d add Echternach. The month before is Luxembourg in November and the year carries on with Luxembourg in January. The whole cold season is in Luxembourg in winter, and every month compared in the best time to visit Luxembourg.

Where the bus does not go, a car does: compare car hire in Luxembourg before you arrive rather than at the desk.
