According to national climate resilience projections, the coastal area of Bolaang Mongondow has experienced an increase in wave height of around 1 meter. It is in the top priority category with high potential hazards and vulnerability or risk of climate change disasters. The rise of the global sea level affects the increase in coastal submergence and erosion and increases the frequency of overtopping of coastal buildings. This research aimed to analyze the extent of the physical vulnerability of coastal Bolaang Mongondow related to the climate change impacts. The coastal area of Bolaang Mongondow was chosen because it is a coastal area with varied lowlands that directly face the Sulawesi Sea (Pacific Ocean). The vulnerability assessment method used in this study was calculating the Coastal Vulnerability Index (CVI). Spatial data interpretation of the parameters of coastal geomorphology, elevation, coastal slope, shoreline change, sea level rise, tides, and significant wave height will contribute to the final vulnerability index value. The results showed that the weight of each analyzed variable varied, ranging from not vulnerable, moderate, vulnerable, and very vulnerable. The CVI assessment shows the less vulnerable category class in all analyzed coastal areas, with index values of 5.86 in Poigar District, 13.1 both in East Bolaang and Bolaang Districts, 14.6 in Lolak District, and 6.55 in Sangtombolang District. Thus, this research concludes that the physical condition of the Bolaang Mongondow coast is less vulnerable to the impacts of climate change. However, it is still threatened in several specific aspects. Although it has not considered socio-economic factors, the assessment of the physical vulnerability of the Bolaang Mongondow coastline produced in this study can be used to formulate targeted mitigation strategies and adaptation measures in the area.
