December weather forecast
Belgium

December in Belgium marks the full onset of winter, with colder temperatures, shorter days, and the appearance of snow, particularly in the higher regions. Average temperatures typically range from 1°C (33.8°F) to 6°C (42.8°F), establishing a clear departure from the relatively mild conditions of November. Both coastal and central regions, including cities like Ostend, Brussels, and Antwerp, experience the winter chill.

In the Ardennes region, the colder temperatures are even more pronounced, with frequent frosts and regular snowfall. The snow-covered landscape provides a stark contrast to the colourful foliage of the autumn months, offering its own unique beauty.

December sees an average precipitation of 70mm (2.76") to 90mm (3.54"), comparable to that of November. However, due to the colder temperatures, this precipitation often falls as snow in many parts of the country, particularly towards the end of the month.

The length of daylight reaches its annual minimum in December, with an average of 8 hours per day around the winter solstice. Despite the reduced daylight, the festive decorations and illuminations in towns and cities across Belgium create a warm and inviting atmosphere.

As December transitions into January, the cold winter conditions persist, and snowfall becomes even more common. Despite the colder weather, the festive season and the potential for a white Christmas make December a magical time to visit Belgium.
