*** 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 Hinterrhein is one of the two headwaters of the Rhine River, located in the Swiss canton of Graubünden. This river flows from the high-altitude sources near the Splügen Pass and continues to the confluence with the Vorderrhein near Reichenau, where they form the Rhine River. The Hinterrhein passes through scenic valleys and offers stunning views of the surrounding Alpine terrain. Its cold, fresh waters originate from glaciers, and the temperature of the river is typically quite low, even in summer, often between 5°C and 12°C (41°F - 54°F), depending on the season and location. Swimming is not common due to the cold temperatures, but the river is popular for rafting and other adventure sports.
