Climate and Average Weather in Belgium

Belgium has a temperate oceanic climate. This means mild winters and cool summers. Average annual temperature is 10 degrees Celsius (50° Fahrenheit). In summer Belgium may suffer from thunderstorms moving north from France. If a high pressure area is coming from the south, there is a chance of wonderful warm summer weather in Belgium.

In winter there can be quite large climate differences between the coastal region and the hills of the Ardennes. While it remains well above freezing along the coast, it can freeze and snow in the Ardennes at the same time. The number of days with snow in the Ardennes is a lot higher than in the rest of the country and the temperature is on average several degrees lower in winter months.

The best time to visit Belgium is in general from May until the end of September.
