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
Rumilly, located in the Haute-Savoie department in southeastern France, is positioned along the Chéran River, a tributary of the Rhône River. The Chéran River is known for its crystal-clear waters, flowing from the Bauges Mountains and meandering through the valley near Rumilly. While the river's scenic beauty is a draw for outdoor enthusiasts, swimming in the Chéran is not very common. The water temperature in the river varies depending on the season but typically ranges from 10°C to 18°C (50°F to 64°F) during the warmer months. This can make swimming quite cold, especially in spring when the river's waters are fed by melting snow from the mountains, resulting in colder conditions.
For those wishing to swim in safer, more controlled environments, Rumilly offers nearby leisure centers and swimming pools. These facilities provide a comfortable temperature for swimmers and cater to families, recreational swimmers, and those seeking a more relaxing experience. For adventurous swimmers, there are also certain areas along the Chéran where you can wade or enjoy a cool dip in the water, though it is recommended to exercise caution due to the river's flow and cold temperatures. Additionally, the surrounding natural environment offers numerous opportunities for hiking, picnicking, and other outdoor activities, making Rumilly a popular spot for nature lovers.
