Belgium Weather Guide

Unpredictable is the best word to sum up the weather in Belgium. It chops and changes frequently, just like our Melbourne town. Areas near the seaside experience mild and somewhat humid conditions, while inland cities are warmer. Belgium has a temperate maritime climate influenced by the Atlantic where summers are fairly warm and it often snows in winter.

Season and Clothing

Summer: June to August

Unlike many places in Europe, it’s not high season in all parts of Belgium during the summertime. Brussels, in particular, offers lower room rates in the summertime from July to September. You will find crowds in Bruges though, as adventurous sorts lace up their hiking boots. With average temps around 23 degrees Celsius and most of the festivals held during this time of year, summer is a great time to visit Belgium.

Autumn: September to November

In the beginning of autumn, there’s still a few weeks of summer-like weather. It’s quite a good time to visit because it rains less (particularly in September) and the countryside in Wallonia is picture-perfect. Temps in September are on average around 21 degrees Celsius, but come November, they dive to around 9 degrees so make sure you pack some warm clothing for layering..

Winter: December to February


It can get pretty cold in the winter with the lowest temps in December and January. Generally, the average winter temps in Belgium will be around 6 degrees Celsius with lows of around zero overnight. On especially cold winters, canals and lakes will freeze over making them perfect for ice-skating! The days are crisp and clear and it’s the perfect time of year to come if you want to skip the crowds in the museums.

Spring: March to May

Spring in Belgium is a popular time of year for hikers and adventurous sorts. The landscapes are dotted with spring flowers and the weather is a little more predictable. At this time of year, the hilly and forested area of the Ardennes will be quite busy as it’s a popular destination for locals and visitors alike. The temperature for the season ranges from 10 to 18 degrees Celsius on average.
