Current water temperatures from 48 measuring stations around France. Data from Météo-France Hydroobs is updated daily.
Water temperature is measured by Météo-France at selected coastal and lake beaches. The measuring stations report daily, mainly during the bathing season (May-September). A comfortable bathing temperature is usually considered 18°C or warmer; warm water is 22°C+. Note that local variations can be large — a shallow bay can be several degrees warmer than open water.
