About Bracklesham Bay wave buoy
Bracklesham Bay is a Channel Coastal Observatory National Network wave station off the West Sussex coast. Its nearshore position records conditions entering the broad bay between Selsey and Hayling Island, supporting coastal management along an exposed beach frontage west of Chichester Harbour.
Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
