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
Castrop-Rauxel is a city located in the northern part of the Ruhr area, in North Rhine-Westphalia, Germany. It is stationed on the Emscher River, a small, relatively narrow river that flows northwest through the region. The Emscher River has historically been the central wastewater canal for the Ruhr area, which means its water quality and temperature have largely been influenced by industrial and domestic waste disposal.
The Emscher River's water temperature varies throughout the year. During summer months, it can reach up to 18-20 degrees Celsius, while it typically drops to near freezing in winter. However, it's crucial to note that the Emscher River has long been synonymous with pollution due to heavy industrialization in the Ruhr Area. For this reason, swimming in the Emscher River is generally not advised due to potential health risks.
Efforts have been ongoing for several years now, under the auspices of the Emscher Cooperative, to clean up and renaturalize the river. The ambitious Emscher conversion project aims to transform it from a sewage canal back into a close-to-nature river by 2025. While these restoration efforts have significantly improved the river's quality, swimming is still not recommended as per current guidelines until further notice.
