= Significant wave height
{wiki=Significant_wave_height}
Significant wave height (often abbreviated as Hs) is a measure used in oceanography and meteorology to quantify the height of waves in a body of water. Specifically, it is defined as the average height of the highest one-third of the waves observed over a specific period. This metric provides a useful representation of the wave conditions because it tends to give a more accurate portrayal of the sea state than simply taking the average of all wave heights.
