Computer model simulations of ocean waves for the waters surrounding various Pacific islands from Simulating WAves Nearshore (SWAN) as well as globally and regionally from WaveWatch III (WW3). These provide a scientific prediction of current and future sea state; as with any forecast, however, accuracy cannot be guaranteed and caution is advised.
