High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.
Belgian Coast (West Flanders - Ostend, Knokke, De Panne)
December rotates between brisk, damp days and occasional clear, cold mornings; holiday markets in coastal towns like Blankenberge and Ostend add festive cheer despite the weather. Short daylight hours and strong winds make outdoor plans shorter; snow is rare at sea level but not impossible during cold snaps. For travelers, this is low-season comfort: warm layers, waterproofs, and flexible itineraries work best, and cozy seafood restaurants feel especially inviting.
Flanders & Canal Cities (Bruges, Ghent, Antwerp)
December feels festive in the canal cities as Christmas markets and lights animate central squares, though the weather is typically cold, wet and windy rather than snowy at low altitude. Festive stalls and warm drinks keep streets lively, but outdoor boat tours are limited and mornings are often grey. Pack a warm coat, waterproof footwear, and enjoy off-peak museum time when streets are less crowded between tour groups.
Brussels & Central Plateau (Brussels, Leuven, Mechelen)
December is festive with Christmas markets around Grand-Place, but weather tends to be cool, damp and occasionally windy rather than snowy at city altitude. Short days limit sightseeing hours but the city’s holiday lights and indoor concerts provide plenty to do. Bring warm, waterproof layers and comfortable shoes; expect busy but cozy indoor venues and quieter streets outside main market areas.
The Ardennes & High Fens (Spa, La Roche-en-Ardenne, Malmedy, Baraque Michel)
December alternates between wintry days with snow on the higher ground and wet, cold conditions lower down; Christmas markets in Spa and small towns create seasonal highlights. Short days limit long hikes, but cozy inns and thermal centers are excellent for off-season visits; cross-country trails in the High Fens may be usable if snow permits. Bring insulated boots, thermal layers, and allow extra travel time on rural roads prone to ice and snow.
