About Perranporth wave buoy
Perranporth is a National Network Datawell Directional WaveRider in about 14 metres of water off Cornwall's exposed north coast. First deployed on 18 December 2006, it records Atlantic swell approaching Perranporth and neighbouring beaches; a separate shore station supplies the local weather context.
Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
