In the ocean surface, there are currents generated by ocean winds. Therefore, ocean wind observation is important to grasp of the ocean currents. Ocean wind is changed temporally and spatially. Ocean winds observation should be widely at short intervals, because ocean winds are changed temporally and spatially. High frequency (HF) radar can be observed temporally and spatially velocity of ocean surface currents. Although ocean winds cannot be measured directly by HF radar, it is possible to estimate using wave height, wave period, and SMB method. In this study, ocean winds were estimated by obtained wave height and period from HF radar and SMB method. However, it is highly possible that "swell" was effected ocean wind estimation. Finally, effect of swell on wind speed estimation method using HF radar was investigated.
