This coastal area is a strategic area for human activities such as habitation, tourism, and cultivation. This coastal area is also an area that is threatened when there is a change in activity in the ocean or land. This change in activity can be caused by rising sea levels or changes in wind speed that occur in certain circumstances. And these events can cause extreme storms and waves in the oceans. This event will have an impact in the form of erosion where the shoreline changes on the seacoast. The extreme waves that arise can be caused by a tropical cyclone that occurs in the south of Bali. This tropical cyclone has strong winds and clouds. Tropical cyclones have a profound impact on the places in their path. This impact can take the form of strong winds, hours of heavy rain, even days that can result in flooding, high waves and storm surges. Tropical cycles can rotate the water and cause high sea waves. In this thesis, the cyclone used is the tropical cyclone Riley, which lasted for 3 days from 24 January to 26 January 2019. This thesis will model significant waves in the island of Bali. Modeling is done using the SWAN (Simulating Wave Nearshore) software method. A significant increase in waves resulted in an increase of up to 115,407% at the observation point.
