The weather in Belgium is fairly grey throughout the year. The country's climate is temperate and not uncomfortable, but precipitation is constant through various seasons. Rain becomes a normal part of life, but when mixed with the stark coldness of winter, it can prove challenging for newly arrived expats.

Maritime influences from the North Sea and the Atlantic Ocean make for cooler summers and moderate winters. Temperatures range from 72°F (22°C) during warmer months to 39°F (4°C) during colder months. The country's small geographic size means that the weather in Belgium is relatively uniform throughout, with only a slight variation in the Ardennes region. The higher elevation in this area brings colder temperatures and more snowfall.

Expats living in Belgium will quickly learn to bring along something waterproof wherever they go, even if sunshine and blue skies start the day.
