Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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 Arc River in southeastern France flows through the Alpes-de-Haute-Provence and is fed by mountain streams and glacial meltwater, keeping its water relatively cool throughout the year. During the summer, the water temperature typically ranges from 10°C to 18°C (50°F to 64°F), influenced by seasonal snowmelt from the surrounding Alpine regions. In spring and early summer, the water may be even colder due to increased glacial runoff, creating a refreshing but brisk environment.
While the Arc’s scenic landscape may attract visitors, swimming in the river is generally not recommended. The swift current and cold temperatures can pose challenges even for experienced swimmers, making the river more suitable for kayaking and fishing than casual swimming. Those interested in water activities should look for calmer and warmer sections or visit nearby lakes, which tend to offer safer conditions for swimming. Locals and visitors alike are advised to exercise caution, especially during the spring melt when the river’s flow can be particularly strong.
