Wave forecasts represent open-water conditions; conditions in rivers, harbors, and sheltered waters may differ. Forecast wave heights represent significant wave height, roughly the average height of the highest third of waves. Individual waves can be twice this height or more, so the forecast does not represent the maximum wave height.
