It is known that the ship entering into harbor is limited at the Japanese coastal harbors under severe wave conditions. This limit is critical for the on-schedule service and safety of the maritime transportation. The authors reviewed the distinguishing appearance of the small waves and the safe timing for the ships to enter the harbors at small wave grouping. In this paper, we review the technique to forecast the waves at the harbor entrance to support the incoming ships under rough weather. The consideration on the positive wave forecast for the ships presents the conclusions as follows : (1) The wave information necessary for the ships under rough weather is that of the wave grouping which the ships would receive at the turning point around the harbor entrance. If the grouping is forecast immediately before the turning point, the ships can pass the point in the small wave grouping. (2) The supporting system for ships to enter a harbor can be constructed by the layout indicated in Fig. 13 as an example. (3) The proposed display to forecast the timing for the ships to enter the harbor at the small wave grouping around the entrance and the ship speed is indicated in Fig. 14.
