To improve the probability of decent weather, visit Antwerp between May and September.November to March sees the crappiest weather descend on the city and soak it to its concrete marrow, while May to August is when the grey skies and precipitation are occasionally leavened by some of that blue stuff overhead and a bit of sunshine. The average daily minimum temperature in Antwerp over its fairly mild winter season is 3°C (32°F) and the maximum is 6°C (43°F); summer temperatures can sneak up to a luke-high 25°C (77°F), though July and August can also be the wettest months.
