Weather in Brussels

Best time to visit

With warm summers, mild winters and a lively programme of annual events, Brussels is a joy to visit in any season.

Spring (March to May) is the best time to visit Brussels, as the weather is warm and it is not yet peak tourist season.

Summer (June to August) is peak tourist season. The city is lively and can feel overcrowded at times. Temperatures are pleasant, averaging 23°C (73°F).

Autumn (September to November) is the perfect season to visit the museums in Brussels. Rainfall is moderate and temperatures usually hover around 15°C (59°F).

Winter (December to February) is a festive season. Christmas markets and sparkling decorations make December a particularly magical time to visit. Temperatures can reach a high of 6°C (43°F).
