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
Dortmund, located in North Rhine-Westphalia, Germany, is a bustling city developed along the banks of the Emscher River. The Emscher River has had a dynamic and complex history, especially regarding its water quality and temperature. The river, which was previously used for dumping industrial waste, has gone through various cleanup programs. However, the water temperature of the Emscher River can vary greatly throughout the year, especially with fluctuating climate conditions. Typical temperatures usually range between 4°C during the winter months up to 20-22°C in the peak of summer.
As for swimming, it's not typically recommended to swim in the Emscher River. Though the quality of the water has improved over the years due to environmental cleanups, the river is still used for industrial and domestic wastewater disposal. There are ongoing programs by the Emschergenossenschaft (the local water board) to improve its condition with an aim to make the river more naturally sustainable. Till the water quality is deemed safe by relevant environmental and health authorities, it is advisable to avoid swimming in the Emscher River in Dortmund. Other leisure activities such as boating or riverside picnics could, however, be possible depending on official guidelines and restrictions.
