Water Temperature: Daily Trends, Historical Records, and Forecast
❌ 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. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

Lac d'Emosson is an artificial reservoir located in the Chamonix Valley, in the canton of Valais, Switzerland. Surrounded by stunning alpine scenery, the lake is primarily used for hydroelectric power generation. It is also a popular destination for hiking, mountain biking, and photography, with spectacular views of the surrounding mountains and glaciers. The water temperature in Lac d'Emosson is generally quite cold due to its high altitude and glacial origins, typically ranging from 5°C to 15°C (41°F to 59°F) during the summer months, making swimming not very common.
