Brussels in April — Full Picture
April is one of the nicest months to visit Brussels — mild, greener, and brighter, with the city firmly out of winter. It averages 14°C/5°C with 55mm of rain (drier than the winter months).
Spring blossoms fill the parks (the Bois de la Cambre, the Parc Josaphat, the Royal Greenhouses of Laeken open to the public for a limited spring window most years — check dates). Café terraces are busy and the mood is high.
Easter usually falls in April, bringing Belgium's serious chocolate season — elaborate Easter eggs and figures in every chocolatier — along with school-holiday crowds and higher prices around the holiday week.
Days are long and increasingly bright, though April is famously showery, so keep a rain jacket close. It's a popular, higher-priced time, so book accommodation ahead, especially over Easter.
Note: the Royal Greenhouses of Laeken (Serres Royales) open only for about three weeks in spring (usually mid-April to early May) — a rare, beautiful sight if your dates align.
What to Wear & What to Pack
Mild spring — around 14°C/5°C. A light jacket and layers, with a sweater for cool evenings, plus a rain jacket for showers. Pleasant by day, still cool after dark.
