*** 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 Mortagne River, a tributary of the Meurthe in northeastern France, flows through the Vosges and Meurthe-et-Moselle departments. Its water temperature varies with the seasons, averaging between 8-14°C (46-57°F) in spring and autumn, and reaching around 18°C (64°F) during warmer summer months. These temperatures provide a cool environment, suitable for brief refreshing dips on warm days, but may be chilly for prolonged swimming. Seasonal rains and snowmelt from the Vosges Mountains influence its flow and temperature, which can vary more significantly during early spring.
Swimming in the Mortagne is generally feasible in calm areas where the current slows, particularly during summer. However, the river remains relatively undeveloped for recreational swimming, and natural fluctuations in water level and flow should be considered before entering. Some locals and visitors enjoy nearby picnic areas and light water activities, but it’s advisable to follow local guidance on safe spots for wading or dipping to ensure a pleasant experience. As with many rivers, it is best to check conditions beforehand, as water levels can shift with rainfall.
