The percentage frequency of occurrence of head, beam, and following seas of specified heights for eight compass headings is presented in isoline analyses for four representative seasonal months in the North Pacific Ocean. Centers of maximum frequency of high seas in the northwest Pacific and Gulf of Alaska in February are likely to encourage voluntary reduction in ship speed upward of 20 percent of the time for westerly headings. An experimental Seattle to Yokohama route in February via the Bering Sea is outlined as an example of operational planning use of the wave climatology charts in this report.
