Belgium’s moderate maritime climate offers relatively mild winters and cool summers. Late spring (April–June) and early autumn (September–October) often stand out for comfortable temperatures and fewer crowds, perfect for canal strolling in Bruges or appreciating Antwerp’s architectural gems. Summer (July–August) can be warm with sporadic rain, but it’s also when many festivals occur, including Tomorrowland, which draws an international crowd. Winter (November–February) is chilly and damp, yet the run-up to Christmas brings enchanting markets, especially in Brussels and Ghent. If you want to avoid peak-season prices while still enjoying pleasant days and vibrant cafe culture, aim for May or September, when you can explore Belgium’s historic towns under softer sunshine and lighter tourist flow.
