NSW Ocean Wave Data Collection Program

The wave data presented online by MHL has been collected under the NSW Coastal Data Network Program managed by the Office of Environment and Heritage (OEH). For more information on coasts, estuaries and floods visit: environment.nsw.gov.au.

MHL collects offshore wave data at seven continuously recording sites off the NSW coast. The ocean wave monitoring sites are based on the Waverider buoy system developed by the Dutch company, Datawell. Waverider buoys are located off Byron Bay, Coffs Harbour, Crowdy Head, Sydney, Port Kembla, Batemans Bay and Eden. To provide deepwater wave data, the buoys are typically moored in water depths between 70 and 100 metres, between 6 and 12 kilometres from the shoreline.

NSW Wave Forecast Tool


The NSW Nearshore Wave Forecast tool provides transformed wave data based on offshore wave conditions from the NSW Waverider buoy network and NOAA WAVEWATCH III model.
