Antwerp, Belgium's second-largest city and one of Europe's great ports, sits in the north of the country on the River Scheldt, on flat, low-lying land near the North Sea coast at approximately 51.22°N, 4.40°E. It has a temperate oceanic climate (Köppen Cfb) — mild, cloudy, breezy and changeable, moderated by the nearby sea — with cool summers, mild winters and rain spread through every month of the year.

Summer, from June to August, is mild rather than hot, with July and August the warmest months — average highs around 22–23°C and cool nights. Genuinely hot days are uncommon, though warm spells can occasionally push temperatures into the low 30s. Atlantic and North Sea air keeps the season changeable, with showers possible at any time, but it is among the sunnier, drier and most pleasant parts of the year, with long daylight hours.

Winter, from December to February, is cold and damp rather than severe, kept mild for the latitude by the sea, with January the coolest month — average highs around 6°C and lows near 1–2°C. Frost is common on clear nights, but hard freezes and lasting snow are relatively infrequent, so winters are more often grey, wet and windy than icy, with short daylight and frequent overcast skies.

Antwerp receives around 800–850 mm of precipitation a year, falling on many days and spread through every month with a slight autumn maximum; rain is usually light drizzle or brief showers rather than heavy downpours. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Antwerp's weather is defined by cloud, wind and the proximity of the North Sea: frequent Atlantic depressions bring changeable, often overcast conditions year-round, and genuinely settled spells are the exception rather than the rule. Its low-lying position on the Scheldt estuary makes it, like much of the Low Countries, attentive to the storm surges that autumn and winter gales can drive up the coast.
