Best Times to Visit Brussels
The best time to visit Brussels is between March and May and September and October, the shoulder seasons; this is when room rates are cheaper and fewer crowds clog the top attractions. This city also experiences all four seasons, and rain is a possibility year-round. Average highs range from about 40 degrees in winter to 70 degrees in summer.
One of the most pleasant times to visit Brussels is the spring, when temperatures range from the mid-30s to the mid-60s and the crowds are fewer (and prices lower).
The summer months mark the height of tourist season in Brussels. The city's streets swarm with crowds of visitors, and long lines often form outside the main attractions.
The festival season wraps up by late September but prices drop and the weather stays mild, making the fall months an attractive time to visit.
The winter weather is wet and chilly, but prices still rise in time for the holidays.
