Brussels in October — Full Picture
October turns cooler and damper as autumn settles in, but the parks colour beautifully and crowds are modest. It averages 15°C/8°C with 75mm of rain.
The Bois de la Cambre, the Parc du Cinquantenaire, and the Forêt de Soignes on the city's edge put on autumn colour — a fine time for a leafy walk. The cultural season is in full swing, with museums, concerts, and exhibitions making indoor days rewarding when it rains.
Clocks go back to winter time late in the month, shortening the evenings noticeably. Skies are increasingly grey and rain is frequent, though daytime temperatures are still manageable.
It's a relaxed shoulder season with moderate crowds and prices, good for a museum-and-chocolate city break paired with the odd dry-day walk.
Note: pack for changeable, damp weather — a warm waterproof jacket and an umbrella earn their place.
