Brussels Weather Guide

Much like Europe, Brussels experiences the true four seasons. While summer tends to be the most popular time to visit, spring is typically regarded as the best time to go by locals. While blue skies are common during this time, don’t be surprised if you run into some rain; it tends to rain around 200 days each year in Brussels.

Season and Clothing

Summer: June to August

Summers are fairly pleasant in Brussels with temps reaching around 23 degrees. Because it’s not boiling hot and a decent amount of rain drops, the flowers and gardens still flourish. Brussels does get the occasional heat wave too, so some days can be pretty hot. Generally on these days, afternoon showers are a welcome relief! Summer is the peak season though, so expect queues and higher rates.

Average temperatures: 12 – 23 degrees Celsius.
Appropriate clothing: Light layers, jeans, t-shirts.
Don’t forget: A coat or jumper for night time.

Autumn: September to November

Autumn can be quite chilly in Brussels. The mornings are crisp and the days are similar to an Australian winter. It’s quite a beautiful time to be in Brussels, the streets are pretty with fallen leafs and the countryside is picturesque with autumn colours. If you’re travelling over in November, make sure you pack some woolies – the mornings can get quite frosty. Brussels receives quite a bit of rain in autumn too.

Average temperatures: 5 – 19 degrees Celsius.
Appropriate clothing: Warm layers, jeans, jumpers and a coat.  
Don’t forget: Scarves, beanies and walking boots

Winter: December to February

The streets are so pretty when it snows on winter mornings in Brussels. Though the snow does melt quite quickly when it warms during the day. It does tend to rain a lot in winter and the temperatures are pretty cold. Mornings are very frosty, so you’ll need to rug up in multiple layers. There are cold snaps too, when it’s bitterly cold, and its best to stay indoors – luckily there are heaps of museums to explore.

Average temperatures: 1 – 6 degrees Celsius.
Appropriate clothing: Warm layers, thermals and a water-proof coat.
Don’t forget: An umbrella, comfortable boots, gloves and scarves.

Spring: March to May

Spring is a lovely time to be in Brussels. It doesn’t rain too much and the temperatures are fairly mild, although the odd drop of snow can fall in March. Late spring is arguably the best time to visit Brussels with clear blue skies and mild temps just perfect for kicking back in the Grand Place. Another great thing about visiting in spring is that it’s before peak season, so you won’t have to fight crowds.

Average temperatures: 4 – 18 degrees Celsius.
Appropriate clothing: Light layers and a jacket.
Don’t forget: Comfy shoes for bike riding.
