(1) Wave heights are in feet and represent the average of the highest
one-third of the waves present, crest-to-trough.
Maximum wave height likely to be observed over a 10 minute interval will be
approximately 1.6 times higher than the wave heights shown on the charts above.
(2) Wave heights include refraction (i.e., the bending of wave directions)
due to shallow-water. However, depending on the steepness of the waves,
the slope of the bottom in the surf zone and the angle of the coastline (or more
precisely, the bottom contours) relative
to the incoming waves, surf can be significantly larger or smaller than the wave
heights depicted along the coastlines above.
