Brussels Weather

With cool summers and chilly winters, the climate is generally unstable and unpredictable throughout most of the year. Winters are characterised by mild days intermixed with freezing temperatures brought about by icy winds blowing in from the Baltic. Much of the city’s rain falls in the changeable spring and autumn months, but fine days during this period are perfect for sightseeing.

Summer

Summers are cool and mild in Brussels, with an average temperature of around 16°C. Although many days are overcast, rain rarely sets in for weeks on end and plenty of days are warm and sunny. Brussels is perfect for those who want to escape the heat of southern European destinations, particularly with the long twilight, allowing you to enjoy a variety of activities in the evening. There are also great deals to be had during summer, with many of the hotels experiencing vacancies at this time of year.

Winter

Cold and chilly weather prevails in Brussels during the winter months, with short days and long nights. However, this can be one of the most charming times to visit the city, with the ancient squares lined with warm, inviting cafés and restaurants creating a magical ambience.

Spring and autumn
These are the most popular times of year to visit Brussels, where the ample parks and gardens are alive with colour and the temperatures are perfect both during the day and at night. Days are a mixture of dull overcast skies and bright sunny weather, while nights are cool enough to enjoy the cosy atmosphere of the city’s dining and drinking establishments. Reservations are a must during these seasons however, as Brussels is packed with tourists and business travellers.
