About Rhyl Flats wave buoy
Rhyl Flats (CCO station 100) is an inshore coastal wave monitoring site at 53.3817°N, 3.6009°W. It’s part of the UK’s regional Coastal Monitoring / Channel Coastal Observatory network, placed to characterise nearshore wave climate for flood risk, erosion studies, coastal engineering and local forecasting. These stations commonly use a directional wave buoy (often a Datawell Directional WaveRider class) and report significant wave height, wave period (peak/mean) and wave direction; many also report sea temperature and, where fitted, nearby meteorology.
