The surface tidal current is influenced by sea-surface wind. So, we investigated the influence of sea-surface wind on tidal current data observed by HF Radar. At first, we carried out harmonic analysis in order to know sinusoidal tidal components. Then we studied the relationship between sea-surface wind and the 25 hours running mean values of tidal current by using multi-regression method. From the study, we obtained following results. (1) Tidal current obtained by HF Radar is strongly influenced by sea-surface wind. (2) The influence in shallow area is larger than the one in deep area. (3) The influence in summer is a little bit larger than the one in winter.
