Bremen, a historic Hanseatic port in northwestern Germany, sits on the River Weser on the flat North German Plain, about 60 km inland from the North Sea, at approximately 53.08°N, 8.81°E. Its northerly, near-coastal position gives it a temperate oceanic climate (Köppen Cfb) — mild, cloudy, breezy and changeable, strongly influenced by Atlantic and North Sea air — with cool summers, mild winters and rain in every month.

Summer, from June to August, is mild rather than hot, with July the warmest month — average highs around 22–23°C and cool nights. Genuinely hot days are uncommon, though occasional heatwaves can push temperatures toward the mid-30s. Atlantic depressions keep the season changeable, with showers possible at any time, but it is among the sunniest, most pleasant times of year, with long northern 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 4°C and lows near 0°C. Frost is common on clear nights, but lasting snow and hard freezes are relatively infrequent, so winters are more often grey, wet and windy than icy, with short daylight and persistent overcast.

Bremen receives around 700–750 mm of precipitation a year, falling on many days and spread through every month with a slight summer maximum from thundery showers; rain is usually light drizzle or brief showers rather than heavy downpours, and autumn and winter are notably windy. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Bremen's weather is dominated by cloud, wind and the influence of the North Sea, with frequent Atlantic depressions bringing changeable, often overcast conditions year-round. Autumn and winter gales sweeping in off the sea are a hallmark of this northern coastal belt, and the low-lying Weser valley, like much of northern Germany, keeps a close eye on North Sea storm surges.
