Abstract: Abstract Marine disasters pose a serious threat to economic and social development; therefore, understanding their occurrence rhythms is of great importance to disaster prevention and mitigation. As a major form of marine disaster in China, storm surges and rough seas are particularly worthy of attention. In this study, statistical data regarding storm surges and rough seas over the past 20 years were collected, and a visual approach was utilized to detect their scope, distribution, and temporal-spatial characteristics. Implementation of disaster prevention and mitigation was then discussed. The results revealed the following: (1) storm surges exhibited significant seasonality (occurring in summer and autumn), while rough sea occurrences occurred throughout the year. (2) The losses caused by storm surges showed clear regional differences. Specifically, the economic losses and death tolls in southern provinces were greater than in northern provinces, but they decreased significantly from 2000–2009 to 2010–2019. (3) The loss caused by rough seas also showed regional differences, with greater loss values in the southern provinces than northern provinces. The total loss has dropped significantly in recent years.
