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 Fourchu is a stunning high-altitude lake located in the French Alps, near the resort town of La Grave. Positioned at about 2,300 meters (7,546 feet) above sea level, this alpine lake is surrounded by rugged mountains, making it a serene and picturesque destination for outdoor enthusiasts. Due to its high altitude, the water temperature in Lac Fourchu remains very cold year-round, with summer temperatures typically ranging from 8 to 12°C (46 to 54°F). As a result, swimming in the lake can be a bracing experience, and it is not generally recommended for prolonged periods, as the water is much cooler than most lakes at lower altitudes.
The lake is more commonly visited by hikers who come to appreciate the beautiful alpine environment and enjoy the scenic beauty of the surrounding landscape. While swimming is technically possible, the chilly water temperature and the lake's remote location make it an activity best suited for those with a spirit of adventure. For those who wish to swim, it is advisable to be prepared for the cold conditions and to have appropriate clothing to warm up afterward. The lake's peaceful setting makes it a fantastic spot for relaxation, photography, and enjoying the natural surroundings rather than swimming.
