About Seaford wave buoy

Seaford is a National Network Datawell Directional WaveRider in about 11 metres of water off East Sussex. First deployed on 22 January 2008, it records waves reaching Seaford Bay between Newhaven and Beachy Head and supports assessment of the town's exposed shingle frontage.

Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
