Under the Koeppen-Geiger classification Belgium climate is considered to be temperate maritime with ample influences by the North Sea and Atlantic Ocean, especially in the coastal region. Farther inland marine influences are less pronounced and the climate is characterized by ample dashes of continental weather.  Summers in Belgium are cool and winters moderate; a small in landmass country, Belgium experiences very little seasonal variation from region to region.

Although the period between April to September is considered to be Belgium’s dry season, rainfall is distributed through out the year. During both fall and winter Atlantic low-pressure becomes stronger, resulting in the emergence of gales and uncomfortable weather. Occasionally easterly winds tip weather towards a more continental type, with warm and dry summers and cold winters, during which temperatures can fall bellow zero.

A rather flat country, Belgium experiences breezy conditions that are more evident in winter and more pronounced along the coastal areas. Hills in the eastern regions result in a cooler and wetter climate with more rainfall and sometimes heavy snowfall in the winter.

Required clothing:
Lightweights with rainwear for summer, waterproof Medium- to Heavyweights for winter. A sweater is necessary almost any time of year.
