❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used.

*** 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
Andermatt lies high in the central Swiss Alps, where the young Reuss begins its course. Because the river here is fed by snowmelt and alpine springs, water temperatures remain cold year-round. In winter, the Reuss in Andermatt is close to freezing, typically around 0–2 °C (32–36 °F). In spring, increased meltwater keeps temperatures low, usually about 3–6 °C (37–43 °F). During summer, even on warm days, the river rarely exceeds 8–12 °C (46–54 °F). In autumn, temperatures quickly fall back below 6 °C (43 °F).
Swimming in the Reuss around Andermatt is not prohibited, but it is generally not recommended for leisure bathing. The water is cold, fast-flowing, and can rise suddenly due to rainfall or snowmelt, creating strong currents. These conditions make swimming suitable only for very experienced cold-water swimmers under controlled circumstances. Most visitors enjoy the river visually or for activities such as hiking and photography, while those seeking warmer swimming conditions usually choose nearby lakes at lower elevations.
