Abstract The waves caused by typhoons pose a serious threat to offshore production activities, especially the sheltering ability of fishing ports. Numerical models are of great importance to forecast the waves generated by typhoons. In this study, the MIKE21 spectral wave model was combined with the Holland wind field model to simulate the wave characteristics of Kanmen Fishing Port (KFP) under the influence of the typhoon Lekima, and the berthing capacity of KFP was evaluated. The results showed that calculated significant wave height and wind speed were in good agreement with the observations, and the d trend evaluation considered the model performance to be excellent. The model results showed that the significant wave height near KFP was remarkably affected by the typhoon Lekima and the maximum significant wave height in the fishing port exceeded 2 m. When the typhoon Lekima was passing, the KFP with a total area of 3.92 km2 lost 45.2% of its berthing area, and 54.8% of the fishing port's permitted berthing area can only berth 1,348 vessels. When the typhoon was at level 16 (wind speed 52 m/s), 102 small-sized fishing vessels or 72 medium-sized fishing vessels or 44 large-sized fishing vessels would have no place to stay with each additional level (wind speed increased by 5 m/s).
