Bremen is a small, proud city-state in northern Germany, made up of the Hanseatic port city of Bremen and its seaport exclave Bremerhaven, straddling the Weser river roughly 60 km from the North Sea. Once a powerful member of the medieval Hanseatic League, Bremen is famous for its UNESCO-listed Rathaus and Roland statue, the fairy-tale Town Musicians of Bremen, and the artistic Böttcherstraße and Schnoor quarter. Compact, walkable, and less crowded than Germany's larger cities, Bremen combines centuries of maritime trading history with a lively university-town atmosphere.
Bremen has a temperate maritime climate shaped by its proximity to the North Sea, roughly 60 km up the Weser river. Winters are cold and damp rather than bitterly cold (January averages around 3-4°C), while summers are mild and rarely sweltering (July highs typically 21-23°C). Rain falls fairly evenly across the year, with no single dry season, so a compact umbrella or rain shell is useful in any month. Grey, overcast skies are common, especially from November through February, while May through September brings the longest daylight and the best chance of sustained dry, mild spells.

The seasons
What to expect in each part of the year.
Spring
Months: Mar-May
Temperatures climb from a cool 8°C in March to a pleasant 16°C by May. Buergerpark and the Wallanlagen come into bloom, and outdoor cafe seating reappears along the Schlachte. Rain showers remain frequent but are typically brief.
Summer
Months: Jun-Aug
Mild rather than hot, with highs of 19-23°C and occasional warmer spells into the high 20s. This is Bremen's liveliest season, with Breminale in July, beer gardens along the Weser, and long evenings for sightseeing.
Fall
Months: Sep-Nov
September is often the year's most pleasant month, mild and comparatively dry. October brings cooling temperatures alongside the Bremen Freimarkt, and November turns notably grey, damp, and cold as the city heads into winter.
Winter
Months: Dec-Feb
Cold and damp with average highs of only 4-6°C, though heavy snow is uncommon on the coast-influenced lowlands. The Bremen Christmas markets (Marktplatz and the medieval Schlachte-Zauber) run from late November through December, giving the season a festive lift despite short days.
