You've probably heard the rumors. People say the weather in Belgium Antwerp is basically just one long, damp, gray movie scene where everyone carries an umbrella and forgets what the sun looks like. Honestly? That's kinda dramatic.
Sure, if you show up in November, you're going to see some clouds. But Antwerp’s climate is way more nuanced than the "rainy city" stereotype suggests. It’s a sub-oceanic rhythm. It’s the Atlantic Ocean breathing over the Scheldt River, bringing cool summers and winters that feel colder than the thermometer says because of that biting, humid wind.
If you're planning a trip, you need to understand that the weather here doesn't just change by the season; it changes by the hour. You can wake up to a "Belgian gray" sky, have a literal heatwave by lunch, and find yourself in a lightning storm before dinner. It’s a mood.
The Reality of the "Rainy" Label
Let’s get the wet stuff out of the way first. People freak out about rain in Antwerp, but it’s rarely a monsoon. It’s more of a persistent, fine drizzle that locals affectionately (or not) call motregen.

Statistically, December is the wettest month, averaging about 3.5 inches of rain. Compare that to April, the driest, which only sees about 1.2 inches. You’ve actually got a decent chance of staying dry if you time it right. Interestingly, July often sees high rainfall too, but that’s usually from short, intense summer thunderstorms rather than the week-long gray gloom of winter.
Seasons in the Diamond City
Antwerp doesn't do "extreme" well, but it does "unpredictable" perfectly.
Spring: The Great Awakening
From March to May, the city literally changes color. Temperatures start at a crisp 45°F ($7°C$) in March and climb to a much more manageable 65°F ($18°C$) by May. This is the sweet spot. The crowds at the MAS museum haven't peaked yet, and the terrace culture starts to kick in. You'll see locals sitting outside with blankets over their knees at the first sight of a 15°C day. It’s optimistic.

Summer: Long Days, Short Tempers
June through August is beautiful. Honestly, it is. The sun stays up forever—around 16 hours of daylight in June. Highs usually hover around 73°F ($23°C$), though 2026 and recent years have seen heatwaves pushing past 90°F ($32°C$). When that happens, the humidity makes the city feel like a sauna. Pro tip: many older buildings in Antwerp don't have AC. You’ve been warned.
Autumn: The Golden Haze
September is a hidden gem. The air is still warm, but the light gets that low, golden quality that makes the Grote Markt look like a painting. By November, though, the "unpleasant" weather kicks in. Expect wind. Lots of it. The wind off the Scheldt can make a 50°F day feel like 35°F.
Winter: Lights and Layers
Winter (December to February) is rarely "white." You might get a dusting of snow that turns into gray slush within three hours. It’s mostly just cold and windy, with temperatures hovering around 34°F to 44°F ($1°C$ to $7°C$). But the Christmas markets and the lights along the Meir make it feel cozy rather than depressing.

What Most People Get Wrong About Packing
Most tourists overpack for the cold and underpack for the rain. Or they bring a massive umbrella that immediately gets destroyed by a North Sea gust.
- Skip the umbrella, get a hood. Wind-resistant raincoats are the unofficial uniform of Antwerp.
- Layers are your best friend. A thin merino wool sweater under a windbreaker is better than one giant parka.
- Waterproof shoes are non-negotiable. Antwerp is a walking city. Wet socks on cobblestones will ruin your day faster than a closed chocolate shop.
Surviving the Weather in Belgium Antwerp Like a Local
If you want to handle the weather in Belgium Antwerp like someone who actually lives there, you have to stop checking the forecast three days in advance. It’s useless. The Royal Meteorological Institute (RMI) does its best, but even they know the North Sea is unpredictable.
Instead, look at the sky. If the clouds look "heavy," head for a museum or a cafe. Antwerp has more cafes per capita than almost anywhere else, and that's not an accident—it's a weather-defense mechanism.
Actionable Advice for Your Visit
- Download the Buienradar app. It’s what everyone uses to see exactly when the rain starts and stops down to the minute.
- Plan indoor "escapes." If the forecast looks dodgy, save the Plantin-Moretus Museum or the Antwerp Central Station (a palace in its own right) for the rainy patches.
- Embrace the terrace. Even if it’s drizzling, if the heat lamps are on, sit outside. It’s the Belgian way.
- Check the wind chill. In Antwerp, the "Feels Like" temperature is the only one that actually matters.
The weather in Belgium Antwerp isn't something to fear; it's just something to prepare for. Whether it's the crisp breeze of a spring morning or the misty glow of a winter evening, the city's character is tied to its climate. Pack a good jacket, keep your plans flexible, and remember that the best Belgian beer always tastes better when you're ducking out of a sudden shower.
