Brussels has a resolutely northern European climate. While the winters can be cold and temperatures can dip below freezing, they more commonly hover around 2°C-5°C (36°F-41°F). Spring usually brings rain (usually in fairly short, sharp bursts) while the summer months are usually (June through August) are drier. Summer temperatures are warm but not hot, usually hitting a pleasant 22°C (72°F). Don’t get complacent in the summer though--the temperature dips in the evenings and it is rare that you’ll be able to sit out in shirt sleeves once the sun has gone down.
In March, Brussels gives you the perfect opportunity to discover that the city’s cuisine has more to offer than just mussels and beer during RestoDays (www.restodays.be). Dance the night away at the hedonistic Fête de la Musique (www.fetedelamusique.be) music festival in June, or sunbathe beside bikini-clad locals on the urban sands of Brussels Beach (www.blb-bb.be) during the summer months. The chilly festive season starts at the end of November with the Plaisirs d'Hiver (www.plaisirsdhiver.be) winter fair. You can see Grand-Place sparkling with fairy lights and wander through an alpine village lined with chalet market stalls in Place Sainte Catherine.
