Why do I observe waves coming from a different direction than is shown in the OrbMap v6.2 Weather Module wave display?
In OrbMap v6.2 the wave information shown under the “Wave Height” icon is now the “Significant Waves.” Significant Waves combine the waves with the swells to better estimate the impact of the waves on the vessel. The direction of the significant waves is defined as the direction that imparts the most energy at a given point. In areas of low wind-waves but high swells, the significant wave direction will coincide with that of the swells. In areas of high wind-waves, the significant wave direction will coincide with that of the winds. Keep in mind that you can monitor the wind strength by selecting the “Wind” icon in the OrbMap Weather Module. You can view the swell information by selecting the “Swell” icon.
