*** 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 Grosne River, flowing through the Burgundy region in eastern France, is known for its scenic beauty as it winds through Saône-et-Loire. During the summer months, the Grosne’s water temperature typically ranges from 18°C to 22°C (64°F to 72°F), making it suitable for cooling off during hot days, especially in the shallower parts where wading is popular. While the river is not particularly deep, there are sections where swimming is possible, albeit more for light dips than extensive swimming due to the river's gentle current and moderate depth.
In the cooler seasons, the Grosne’s water temperature drops to between 5°C and 12°C (41°F to 54°F), which generally deters swimmers. However, the river is still a popular spot for nature lovers, hikers, and those who enjoy riverside picnics, as its banks offer beautiful views of the Burgundy countryside. The Grosne is especially appreciated by families and those seeking a peaceful, natural setting, with shaded areas ideal for rest and relaxation by the water. Although swimming options may be limited, the river offers an inviting environment for enjoying the outdoors.
