Hs, the Significant Wave Height, may be defined as the average of the highest one-third of waves and is sometimes described as the wave height which would be reported by an experienced observer. The wave climate at any location can be, and usually is, a combination of sea and swell and is often referred to as the total wave. At Geraldton, the division of sea and swell has been set as 8 second period waves.
