Annual joint distributions of wave height versus wave period for 

 Gauge 630 are presented for 1995 in Table 4, and for all years combined in 

 Table 5. Similar distributions for the other gauges are included in Appendixes 

 B-E. 



Annual distributions of wave directions (relative to true north) based 

 on daily observations of direction at the seaward end of the pier and height 

 from Gauge 625 (or Gauge 1 1 1 when data for Gauge 625 were unavailable) are 

 shown in Figure 13. Monthly wave roses for 1995 and all years combined are 

 presented in Figures 14 and 15, respectively.
