*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Bremerhaven, located in Northern Germany in the state of Bremen, sits at the mouth of the River Weser which feeds directly into the North Sea. The water temperature in the River Weser fluctuates significantly throughout the year due to its geographical location and climatic conditions. The temperatures typically range from around 4 degrees Celsius during Winter (December - February) to up to 20 degrees Celsius in the Summer (June - August), although this can vary slightly from year to year.
As far as swimming goes, while the water temperatures in the late Summer months can be tolerable for outdoor swimming, swimming in the River Weser is generally not recommended. This is primarily because of potential health hazards, such as strong currents and on rare occasion poor water quality due to runoffs from surrounding agriculture and industry. River swimming also requires certain skill and caution as the flow of water can be unpredictable. For safe swimming options, the local outdoor or indoor public pools in Bremerhaven can be a more suitable choice. Always remember to check local guidelines and seek advice before attempting to swim in bodies of water you are unfamiliar with.
