This study has developed a wave hindcasting system that can accurately determine wave conditions in near real-time (within an hour), which is essential for disaster response, offshore construction work, and other maritime operations. The system uses two wave models, WAVEWATCH III (WW3) for the external domain and Simulating WAves Nearshore (SWAN) for the seas around Japan (inner domain). Wind-forcing is provided by an atmospheric analysis GPV that offers accurate 10 m wind with a horizontal resolution of 2 km available every 30 minutes. To ensure predictive accuracy, the real-time wave hindcast system results were compared with observed wave data at various locations, and the statistical results showed that the predictions were equally or slightly precise compared to the those using the hourly analyzed atmospheric GPV.
