The coldest months are January and February, with average temperatures around 4.0-4.5°C, while nighttime temperatures usually remain above freezing. A distinctive feature of the weather in Bremerhaven is the fairly high number of days with precipitation throughout the year, although the total amount of rainfall is small, usually 2-4 mm per month.

In Bremerhaven, precipitation falls fairly evenly throughout the year, and there is no clearly defined dry or rainy season. The city is characterized by frequent but generally not very heavy rainfall. Even in months with the lowest recorded rainfall, rain or drizzle is common.

If we talk about the wettest periods, the highest amount of precipitation in millimeters (about 4 mm) usually falls in October. However, the winter months lead in terms of the number of days with precipitation: January and December, each of which has an average of 18 wet days. Given the average temperatures in these months (from 2.5°C to 6°C), precipitation can fall as rain, snow, or sleet. July, October, and November also stand out for their high frequency of precipitation, with 17 wet days each.

The lowest total amount of precipitation (about 2 mm per month) is observed in spring – in March, April, and May. At the same time, May is the month with the fewest rainy days – about 12 on average. In general, Bremerhaven is characterized by frequent but light precipitation, whether rain or drizzle, so it's worth having an umbrella or raincoat with you when planning a trip at any time of year.

When planning a trip to Bremerhaven, it's important to be prepared for the changeable weather typical of a coastal city. Given the high number of days with precipitation throughout the year (from 12 to 18 per month), even if the total volume is small, a waterproof and windproof jacket will be your best companion. Don't forget comfortable walking shoes, preferably water-resistant, as you will likely be walking a lot. The principle of layering clothing is especially relevant here: it will allow you to easily adapt to temperature changes, which can be felt due to the wind, and to comfort levels throughout the day.

In the summer months, from June to August, when the average temperature is around 17-19°C, light items such as t-shirts, shorts, or light trousers will be useful. However, it's a good idea to bring a sweater or a fleece for cool evenings or windy days by the sea. Sunscreen and a hat may also be needed on clear days. For trips during the colder months, from November to March, when average temperatures drop to 4-6°C, be sure to pack a warm winter jacket, warm sweaters, a hat, scarf, and gloves. During the shoulder seasons (April-May and September-October), the weather can be quite unpredictable, so a combination of a mid-season jacket, several layers of clothing, and an umbrella or raincoat will be the most sensible choice for a comfortable stay in Bremerhaven.
