Figure 16. Maximums and means of significant wave height for Atlantic City; determined 

 from 7-rainute pen-and-ink records taken six times daily during 1964-65 and 

 1967. Values for September were obtained by determining the mean from the 

 respective plot for height and period for 1965 and 1967, then weighted by the 

 number of observations during 1964, 1965, and 1967 to arrive at an average for 

 the years 1965 and 1967; all other average values include the monthly values 

 for 1964, 1965, and 1967 (from Thompson, 1977).
