About Watermael-Boitsfort in April
Watermael-Boitsfort borders the 4,400-hectare Sonian Forest, which profoundly shapes its microclimate — summer temperatures run 4–6°C below the city centre, and the forest generates cool katabatic air flows on calm evenings. The neighbourhood's garden-city layout with abundant mature trees amplifies this cooling effect, making it Brussels' coolest inhabited commune.
