Brussels Weather in October

October weather

Brussels feels cool and properly autumnal in October. Afternoons can reach 16°C, but evenings fall to 8°C. Rain comes on 13 days, and grey skies are common, so don't count on a long, sunny day outdoors.

Dry spells suit a walk around the Grand-Place or through Parc de Bruxelles. When rain sets in, swap park time for the Magritte Museum or the covered Galeries Royales Saint-Hubert. You can still enjoy the city; just keep outdoor plans flexible.

What to do

The Brussels Museums Nocturnes bring late openings and special events to participating museums on autumn evenings. It's a nice way to see a collection without giving up your daytime sightseeing.

Families who prefer indoor outings will find October easier than a day built around parks and playgrounds. For a rainy spell near the Grand-Place, duck into the Galeries Royales Saint-Hubert, the elegant covered arcade, and browse its chocolate shops.

Crowds and costs

October is quieter than the summer peak and September, one of Brussels' best months overall. You'll usually find fewer visitors around central sights, while prices can be gentler than in the busiest months. Still, popular museums and central hotels can draw plenty of people, especially around event nights.

October has less daylight than September, and the weather can interrupt long walks. Plan a museum or café stop around an outdoor visit, rather than trying to spend the whole day outside. A warm waffle in a café near the Galeries makes a welcome pause when the rain starts.
