*** 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
Sélestat, located in the Alsace region of northeastern France, lies along the Ill River, a tributary of the Rhine. The water temperature in the Ill River varies significantly depending on the season, which influences the possibility of swimming in the river. During the winter months (November to March), the river's water temperature typically ranges between 4°C and 8°C, making swimming unsafe due to the cold water. In addition, the strong currents and potential for high water levels from snowmelt or rain in winter further discourage swimming during this time.
As the weather warms up in spring and summer (April to September), the temperature of the Ill River rises, creating more favorable conditions for outdoor water activities. By the summer months, the water temperature can range from 15°C to 20°C, which is generally comfortable for recreational swimming. However, swimmers should remain cautious, as the river's currents can still be strong, especially after heavy rainfall. The riverbanks around Sélestat are not typically developed for public swimming, so it is important for swimmers to ensure they are in safe areas designated for such activities.
Although Sélestat offers beautiful natural scenery along the Ill River, swimming is generally not a widespread activity directly in the river. Visitors are encouraged to explore nearby public swimming pools or lakes in the region, where conditions are more controlled and safer for swimming. Always check with local authorities about water quality and safety guidelines before swimming in the Ill River.
