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
Lac de Roselend is a striking artificial lake located in the Beaufortain Valley in the French Alps. Created by the Roselend Dam, the lake sits at an elevation of 1,557 meters (5,108 feet) and is surrounded by lush alpine scenery, attracting visitors for its scenic beauty and hiking trails. The lake’s water temperature is generally quite cold, even during summer, typically staying between 10 and 15°C (50–59°F) due to the high altitude and glacial melt that feeds it. This makes it more suitable for those seeking a refreshing dip rather than long swimming sessions.
Swimming in Lac de Roselend is possible, but it is not officially recommended or popular due to the cold water and the lake's role as a reservoir for hydroelectric power. Visitors who choose to swim should exercise caution and be prepared for the low temperatures. However, the lake is a favorite spot for picnics, scenic hikes, and photography, with various vantage points offering stunning views of Mont Blanc and the surrounding mountains. For those interested in a cooling experience amidst dramatic landscapes, a quick dip in Lac de Roselend can be a memorable, albeit brisk, adventure.
