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 la Case, located in the Bernex region of the Haute-Savoie, is a picturesque mountain lake surrounded by alpine beauty. The lake lies at a relatively high altitude, which results in a colder water temperature. As is typical for many mountain lakes, the water temperature remains relatively cool throughout most of the year, especially during the spring and early summer when snowmelt influences the temperature. Although it may be refreshing during warmer months, swimming might be challenging for those not accustomed to colder waters. Due to its location, the lake is best suited for hiking excursions, such as those that start from the Fétiuère car park and lead to the lake, offering stunning views of the surrounding mountains, including Mont Blanc. It’s known for attracting marmots, making it a great spot for nature enthusiasts.
