 Fig8.1.5-4: An example of Significant wave height / Mean wave direction and height on ecCharts.  DT Thursday 11 May, 00 UTC T+60, VT Saturday 13 May, 12 UTC.  Note: Dark blue generally indicates areas in open water where waves are forecast to be very small (e.g. among the islands off western Scotland),  but the area of dark blue off the Greenland coast is in effect denoting sea ice.  The ice extent is modified during the forecast by information passed from NEMO to ECWAM.  This may affect the development of synoptic scale developments in the atmosphere with consequent influence over the forecast winds.

Significant wave height / Mean wave direction and height is also available on web free access charts.
