There are many methods calculating design wave elements of coastal engineering. Of course, the best way is based on the datum collected to find the right approach. This paper presents the method of typhoon weather charts of history to calculate design wave elements of coastal engineering, which is based on an example of the design wave elements’ prediction of Rudong artificial island. The results show that in a lack of long-term real-measured wind data, we can use the typhoon weather history charts method to calculate the design wave elements to provide the design basis for the engineering.
