Indonesia has the largest archipelago in the world and more than 2 million people work as traditional fishermen. Traditional fishermen usually use small ships with sizes lower than 30 GT (gross tonnage). This traditional ship is greatly endangered by weather variability and high sea variability, as well as rough seas. Marine risk information is important for comfort and safety in fishing. Marine risk information could be determined by a risk matrix as consequences of rainfall, high wave hazard, and the likelihoods of these events. Wave prediction was simulated by Wavewatch III based on wind prediction from Weather Research and Forecasting (WRF) simulation. Rainfall was obtained from the Tropical Rainfall Measuring Mission (TRMM). The wind spatial value of WRF processed between 1 and 15 March 2017 and averaged from 00 to 12 Universal Time Coordinate (UTC) to represent risk information at daytime and averaged from 12 to 00 UTC to represent risk information at night-time. Mapping of the significant wave information was created by the ArcGis application to generate the marine risk information. Adding rainfall factors from the Tropical Rainfall Measuring Mission (TRMM) to the ArcGis results in marine risk information maps was based on significant wave and rainfall for day and night-time. When the marine risk information maps (both daytime and nighttime) were based only on the significant wave factor, the marine risk level in the southern part of Cenderawasih Bay was generally low. The addition of the rainfall factor increased the general risk level at night to medium. In March, in the southern part of this bay, traditional fishermen were safer fishing in the daytime.
