42. Annual joint distributions of wave height versus wave period for 

 Gage 630 are presented for 1987 in Table 4, and for all years combined in 

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

 B through E. 



43. 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 Gage 625 (or Gage 141 when data for Gage 625 were unavailable) are 

 shown in Figure 13. Monthly wave "roses" for 1987 and all years combined are 

 presented in Figures 14 and 15, respectively.
