WW3 MEDITA – Italia

Sea state forecasts (significant wave height, wave propagation direction, mean period, and peak period) for the Mediterranean basin. Hourly forecasts are provided up to +72 hours by the WW3 (WAVEWATCH III) numerical wave model, which is implemented within the operational forecasting chain managed by ItaliaMeteo and Arpae Emilia-Romagna.

‘Sea state’ refers to the description of wave properties at a given location and point in time. The map visualization displays the significant wave height, expressed in meters, and the corresponding wave propagation direction. ‘Significant wave height’ is defined as the mean height of the highest one-third of waves present in a given sea area, when ordered by increasing height.
