Mean wave heights decrease further north, as exposure to this swell decreases. The significant wave height (H s) is a term used to introduce a well-defined and standardized statistic to denote the characteristic height of the random waves in a sea state.It is defined in such a way that it more or less corresponds to what a mariner observes when visually estimating the average wave height. For example, the No. The wave height is greatest in the Atlantic, moderate in the North Sea and least in the immediate coastal zone where the values are generally <1.2m.
