A site I like is this one - http://152.80.49.204/CGI/ww3_all.cgi?color=b&type=prod&area=npac&prod=sig_wav_ht You can see what wave action is developing in the whole North Pacific. Then you have your Bouy site http://seaboard.ndbc.noaa.gov/Maps/Northwest.shtml which gives you realtime information. Then there's always the NOAA site http://www.wrh.noaa.gov/seattle/ where you just click on your area of interest. They all work about the same.
