Belgium has a temperate maritime climate influenced by the North Sea and the Atlantic Ocean, with relatively moderate summers and mild winters. Since the country is small, there is little variation in climate from region to region, although the marine influence is a little less pronounced away from the coast.
Temperature
The average temperature is about 3°C (37°F) in January, and 18°C (64°F) in July, although on occasion, temperatures have fallen as low as –15°C (5°F) during extreme winters, or gone as high as 38°C (100.4°F) over summer. However, such extremes are very unusual.
Rainfall
The average precipitation is 76.1 millimetres (3 inches) in January, and 73.5 millimetres (2.9 inches) in July. On average, there are 200 days of rain per year.
The annual variation of rainfall:
- In the coastal area, most rain falls in October
- In Lower and Central Flanders, most rain falls during summertime (July-August)
Wind
Usually the wind in Belgium is southwesterly. The average wind speed is up to 3 m/s inland, and 7 m/s on the coast.
