The climate of Bremen, located in Germany, can be described as temperate maritime. This means there are no sharp temperature contrasts here: winters are relatively mild, and summers are usually not exhaustingly hot. The weather is generally comfortable for visiting throughout most of the year, although it has its seasonal specificities.

In Bremen, four seasons are clearly distinct. Winter (December-February) is cool here, with average temperatures around +3°C to +5°C, and is the wettest period in terms of days with precipitation. Spring (March-May) brings gradual warming, with the air warming up from +6°C in March to +13°C in May. Summer (June-August) is the warmest time of the year, with average temperatures around +17°C to +19°C, creating pleasant conditions for walking and sightseeing. Autumn (September-November) is characterized by a gradual decrease in temperature and a continuing probability of rain.

One of the characteristic features of Bremen's climate is the relatively small but evenly distributed amount of precipitation throughout the year – on average 2-3 mm per month. At the same time, it is worth noting the significant number of days with precipitation, ranging from 12 to 16 per month. This suggests that light rain or drizzle can be a frequent occurrence, so tourists are advised to carry an umbrella or raincoat regardless of the travel season.

The climate in Bremen is characterized by moderate temperatures throughout the year, without sharp extremes. The coldest month is typically January with an average temperature of about 3.7°C, when daytime highs rarely rise above 5.6°C, and nighttime lows drop to 1.8°C. February is also cool, with an average value of 4.4°C. Gradual warming begins in spring, and by May the average temperature reaches a comfortable 13.2°C.

Summer months in Bremen are usually pleasantly warm, but not exhaustingly hot. The warmest month is considered to be August, when the average temperature is 18.8°C, and daytime highs can reach 23.1°C. July is also warm, with an average temperature of 18.1°C and a maximum of about 22.3°C. June offers similar conditions with a maximum temperature of around 22.1°C. Nighttime temperatures in summer remain quite mild, dropping on average to 13-14.5°C, which ensures comfortable sleep. The difference between day and night temperatures in summer is approximately 8-9°C.

In autumn, the temperature gradually decreases: in September the average temperature holds at 15.5°C, in October it drops to 12.1°C, and in November the approach of winter is already felt with an average temperature of 6.7°C. Winter is generally mild, with December average temperatures around 4.5°C. Diurnal temperature fluctuations in winter are less pronounced than in summer, amounting to about 3-5°C.

In Bremen, precipitation is distributed quite evenly throughout the year, and it is difficult to single out a clearly defined rainy season or, conversely, a dry period here. According to the provided data, the total monthly amount of precipitation is small and fluctuates within the range of 2-3 mm.

Despite the small total amount, precipitation in Bremen occurs quite frequently. The highest number of wet days usually falls in January and December (an average of 16 days each), as well as July and October (15 days each). Precipitation is observed slightly less often in March, May, June, and September, when about 12 days with precipitation per month are recorded on average. Thus, although months with 3 mm of precipitation (January, February, June, July, October, December) formally receive slightly more moisture than months with 2 mm (March, April, May, August, September, November), the difference is minimal.

The nature of the precipitation, judging by the frequency and small volume, most likely represents light rain, possibly drizzle. In winter months, such as January (average temperature 3.7°C, minimum 1.8°C) and February (average temperature 4.4°C, minimum 1.6°C), as well as in December (average temperature 4.5°C, minimum 2.8°C), there is a probability of snowfall, especially when the temperature drops to or below the freezing point. However, the provided precipitation data is general and does not separate it into rain and snow.

When planning a trip to Bremen, it is important to consider its temperate maritime climate with quite frequent precipitation throughout the year. Regardless of the season, a reliable umbrella and a light waterproof jacket or raincoat will become your faithful companions, as there are on average 12 to 16 rainy days per month. It is also highly recommended to bring comfortable walking shoes, preferably water-resistant, as you will surely want to walk a lot through the charming streets of the city. The principle of layering in clothing is your best friend in Bremen, as the weather can be changeable, and the air temperature fluctuates during the day.

In summer (June-August), comfortable warm weather usually settles in Bremen with an average temperature of about 17-19°C (maximum values can reach 22-23°C). At this time, T-shirts, light trousers or shorts, and dresses will be useful to you. However, even in summer, do not forget a light sweater or cardigan for evening walks or in case of a cool day. In spring (March-May) and autumn (September-November), the weather is cooler and more changeable, with average temperatures from 6°C to 15°C. For these seasons, pack sweaters, jeans, a mid-season jacket (preferably windproof and waterproof) and, possibly, a scarf. In winter (December-February), it is quite cool in Bremen, with the average temperature holding at the level of 3-5°C. Be sure to take a warm winter jacket, hat, gloves, and scarf, as well as warm layers of clothing under the jacket. At any time of the year, be prepared for possible wind, which is characteristic of this region.
