Significant wave height
The average of the highest one third of the waves. The likely maximum wave height can be up to twice the significant wave height, occuring around 1 in 2000 waves.

Significant Wave Height The average height (trough to crest distance) of the one-third highest waves. An experienced observer will most frequently report heights equivalent to the average of the highest one-third of all waves observed.
Significant wave height = average height of the waves which comprise the highest 33% of waves in a given sample period (typically 20 to 30 minutes).

Also known as total wave height, or significant wave height. Combined sea and swell describes the combined height of the sea and the swell that mariners experience on open waters.
WAVE HEIGHT - The measurement of a wave, such as an ocean wave, in vertical distance from crest (high point) to trough (low point). Commonly referred to as SIGNIFICANT WAVE HEIGHT.
When used, SEAS should be considered as being the same as the significant wave height.
