Climate Overview Of Belgium

The climate varies slightly from region to region. On the coastline, it is humid and mild in general, moderated all year round by the maritime influences of the North Sea. The Ardennes highlands, on the other hand, swing from hot during the summer to snowy winters with heavy rains during April and November. Fog, a regular feature of Belgian weather, especially in the Ardennes and the north coast, often disrupts visibility.
May to September is really the best season, warm and pleasant, with average temperatures ranging from about 18 º C in May to roughly 21 ºC in August. In winter, the mercury drops to as low as – 2 º C. Whatever time you do decide to go be sure to carry an umbrella and a sweater!
