Measured Gage Significant Wave Height, m
Figure 9. Comparison of CGWAVE predicted wave heights with measured field sites
are smaller since they propagate away from the area of T1. For T2 going to the PP, waves traveling
to the west are the highest throughout the harbor region for all wave periods. Waves traveling to the
other two directions are nearly the same for the first 400 to 500 m (1,312 to 1,640 ft) from the PP,
where the waves traveling to the southwest are higher.
Wave height statistics were calculated along T1 and

T2 in an attempt to quantify wave heights. The
