*** 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
La Roche-sur-Yon, located in the Vendée department in western France, is a city situated along the Yon River, which flows through the heart of the region. The Yon River, with its tranquil waters and surrounding scenic countryside, provides a pleasant backdrop for various outdoor activities. The water temperature in the Yon River varies throughout the year. In the winter months, the temperature generally hovers around 6°C to 8°C (43°F to 46°F), while in the summer, it can rise to between 18°C and 22°C (64°F to 72°F), making it a more inviting temperature for casual swimming.
Though the Yon River is not a major destination for large-scale swimming, it is still enjoyed by locals during the warmer months, especially in calmer stretches of the river. The river is commonly used for activities such as canoeing and kayaking. For swimming, the Yon River provides some opportunities in certain safe, slow-moving sections, but swimmers should be cautious as the water can be cold and the currents can be unpredictable in certain areas. Those looking for more controlled environments for swimming typically head to local pools or nearby beaches along the Atlantic coast, which are better suited for a full swimming experience.
