Climate and Average Weather in Belgium

Belgium has a temperate oceanic climate and it owes this climate due to the influence of the North Sea. The sea water has a cooling effect on the country's weather during summer, and in winter months it keeps temperatures from dropping too far down.

In general this means mild winters and cool summers with an average annual temperature of 10 degrees Celsius (50° Fahrenheit). During the warmest month July in Belgium, the average temperature ranges from moderate in Botrange with 17°C (63°F) to high in Antwerp with 24°C (75°F). Minimum nighttime temperatures generally drop to 14°C (57°F) in Antwerp and 9°C (48°F) in Botrange.

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. During the coldest month January in Belgium, the average temperature ranges from very low in Botrange with 0°C (32°F) to low in Antwerp with 7°C (44°F).
