Sara and John say...
On holiday at the coast, on business in Brussels or enjoying the wide open countryside, the climate of Belgium, like other western European countries, is generally mild. Extremes of temperature are less marked than further east across the continent.
However, there is variety, relating mostly to altitude and proximity to the sea.
Rainfall is quite evenly distributed through the year, with occasional snowfall in winter. During the coldest months, daytime temperatures typically hover above freezing - in the range 3 to 8 Celsius. But when the prevailing westerly wind changes to an easterly, the door to much colder air can open. The higher parts of the Ardennes can be particularly exposed to these bitter winds; but even here, sub-zero spells don’t often last long. And when Atlantic winds bathe the country it’s much milder, but also damper and breezier, especially near the coast.
Spring brings an erratic rise in temperatures and a fresh greenness to the countryside. But it’s not until early May that the last frosts are behind us.
Summers typically bring a mixture of sunshine and occasional showers, with temperatures in the low 20s Celsius. However, during European heatwaves, highs in the 30s Celsius are not uncommon. The heat also brings humidity, often culminating in thunderstorms.
The autumn months show a gradual cool-down, with an increase in disturbed and windy weather, especially near the coast. However, it’s not uncommon for warm, summer-like spells to occur well into October.
It’s not until November that the dark days bring a more consistent chill to the air, with lingering fog patches suppressing temperatures when winds fall light.
Winter lies ahead, but Belgium stays green, rather than white, for most of the months to come.
