The winters are wet and cool with frequent fogs, the summers are fairly mild. The regional differences in climate are determined by the distance from the sea and height above sea level. Further inland, maritime influences become weaker, and the climate becomes more continental, characterized by greater seasonal temperature variations.

The Ardennes region, the highest and farthest from the sea, is also the coldest region. In winter, we have approximately 129 days of frost, snow fell for 30 to 35 days, and in January the average minimum temperatures are lower than elsewhere. Because of the topography, the Ardennes have also the highest rainfall of Belgium. On the contrary, the Flemish region generally enjoys higher temperatures throughout the year.


The best time for a trip to Belgium are the spring and summer months, when the days are longer and the weather is mild.
