Wave Forecasts

The numerical wave model, SWAN, simulates surface gravity waves for a domain covering Irish waters at a resolution of 0.025 degrees (approximately 1.5km).  The model uses NCEP GFS for wind forcing and FNMOC Wave Watch 3 data for the wave boundaries. A daily 6 day forecast is generated for parameters such as significant wave height, mean wave period and mean wave direction.  

Model data is freely available via our THREDDS and ERDDAP server.

The wave forecast is generated on a best endeavours basis and should not be used for safety critical applications.
