*** 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.

The River Arve, which flows from the Mont Blanc area in the French Alps and crosses into Switzerland before merging with the Rhône River in Geneva, offers varying water temperatures and conditions depending on the season. In the warmer summer months (June to August), the water temperature typically reaches comfortable levels for activities like rafting and kayaking, though it can be chilly for swimming due to the mountain runoff. The water stays cooler in spring and autumn, making swimming less appealing for those seeking warmth but still viable for experienced swimmers in the calmer areas.
The river is popular for whitewater rafting, especially between May and October, as it provides a mix of calm and rapid waters. The Arve's water quality is monitored regularly, especially near Geneva, where the river's clarity and flow are important for the local ecosystem and recreational use. While there aren't many designated swimming areas directly in the river, various adventure activities, such as rafting, make it an exciting option for outdoor enthusiasts. If you're planning to swim or raft, the best time is between late spring and early autumn when the temperatures are more favorable.
