About Sandown Bay wave buoy
Sandown Bay is a Channel Coastal Observatory National Network wave station off the east coast of the Isle of Wight. Its nearshore record represents conditions entering the bay between Culver Down and Dunnose, helping monitor a developed and erosion-sensitive frontage exposed to English Channel seas.
Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
