*** 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
Lake Achard, nestled in the French Alps near Chamrousse in the Isère department, is a small, scenic mountain lake at an elevation of approximately 1,917 meters (6,289 feet). Due to its high altitude, the lake remains cold year-round, even in the summer months. Water temperatures rarely exceed 15°C (59°F) during the warmest periods, which makes swimming quite invigorating but refreshing for those accustomed to colder waters. The lake is accessible by a popular hiking trail and is surrounded by beautiful alpine meadows, making it an ideal location for both hiking and a quick, cooling dip.
Swimming in Lake Achard is allowed, but it is recommended only for the more adventurous, given the chilly temperatures. Many visitors enjoy wading or briefly immersing themselves rather than long swims, as the water can feel especially cold after a hike. The lake’s peaceful, clear waters and surrounding landscape make it a popular spot to relax, have a picnic, and enjoy the stunning views. For a more comfortable experience, swimming here is best in July or August when the lake reaches its warmest point, though it remains a chilly but rewarding experience for mountain enthusiasts.
