We develop a real-time wave information and analysis system on the basis of a data assimilation technique, the optimum interpolation method, applied for wave observation data and forecasted data. The system can provide nowcast wave information for the sea area where there is no wave observation point. In the system, first, the initial estimate (nowcast) is computed in real-time with the observation data and forecasted information, and then the estimate is corrected after 12 hours with more accurate forecasted wave information. Finally, the corrected data is stored in the wave information database for analysis. We investigate the characteristics of the nowcast wave data and confirmed that the accuracy of the data is high enough for practical applications.
