About Royan wave buoy
Royan is part of CANDHIS, France's national in-situ sea-state observatory coordinated by Cerema and its regional partners. The station lies off the mouth of the Gironde, where Atlantic swell meets a wide, shallow and strongly tidal estuary beside the resort coastline of Royan.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
