Since 1970, the Port and Airport Research Institute (PARI) has been cooperating with the Bureau of Ports and Harbours, Ministry of Land, Infrastructure, Transport and Tourism, and its associated agencies, on the Nationwide Ocean Wave information network for Ports and HArbourS (NOWPHAS). The PARI has been processing and analyzing the wave records obtained at this network, and has presented the wave statistics in a series of annual reports. This Technical Note is the 2007 version of the series, and covers the wave data obtained throughout 2007 at the 61 network stations. The wave statistics at each station are presented in the following forms:
　(1) Largest significant wave at each station since the observation started,
　(2) Maximum and mean significant waves during the year,
　(3) Joint distribution of the significant wave heights and periods,
　(4) Joint distribution of the significant wave heights and directions,
　(5) Wave characteristic parameters during extremely severe sea states,
　(6) Results of the infra-gravity wave height analysis,
　(7) Results of the directional spectra analysis based on the frequency-banded description.
