WAVE HISTORY

WAVE HISTORY displays a timeseries of Hmax, H1/10, H1/3 over the last 24 hours, where Hmax is the largest wave recorded in the sampling period, H1/10 is the average of the largest 1/10 of waves sampled and, H1/3 is the largest 1/3 of waves sampled. Wave heights are determined using wave train analysis where individual waves are identified using the crest-to-trough method, i.e. by calculating the crest-to-trough difference between consecutive zero up-crossings.
