*** 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.

The Neckar River, flowing through southwestern Germany, is a significant tributary of the Rhine and offers both scenic beauty and recreational activities. Water temperatures in the Neckar vary by season, generally ranging from 4–6°C in winter to 18–22°C in the summer. In warmer months, these temperatures can make the river inviting for water activities in certain areas, particularly where conditions are calmer and safer for swimming.
Swimming in the Neckar is permitted only in specific areas due to safety concerns, such as strong currents and the presence of commercial shipping traffic. Popular spots for recreational swimming include quieter sections of the river or associated lakes and reservoirs, such as the recreational areas near Stuttgart or Neckartailfingen. These locations provide a more controlled environment, often with facilities and supervision, making them suitable for swimmers of all levels. However, swimmers are encouraged to exercise caution, adhere to safety guidelines, and avoid areas with heavy boat traffic.
