how tall are storm waves ocean
This model assumes that waves vary in a regular way around the average (so-called 'significant') wave height. In a storm sea with a significant wave height of 12 metres (39.4 ft), the model suggests there will hardly ever be a wave higher than 15 metres (49.2 ft). One of 30 metres (98.4 ft) could indeed happen â but only once in ten thousand years (of wave height of 12 metres [39.4 ft]).
