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.
