520			_aThe study investigated the wave conditions of tropical cyclones along the coastline of Ilocos Norte, Philippines, a region highly vulnerable to climate change. Historical data from PAGASA and Gumbel’s formula were used to calculate the return periods of cyclones from 1960 to 2022. The Simulating Waves Nearshore (SWAN) and Geographic Information System (GIS) were employed to calculate and produce maps showing simulated wave conditions, including maximum significant wave height, wave period, and a wave rose diagram. Findings indicate that a storm similar to tropical cyclone Narsing is expected every five years with a maximum significant wave height of 4.14 meters and a wave period of 7.02 seconds, predominantly affecting the municipalities of Burgos and Bangui; Herming every ten years with a maximum significant wave height of 5.25 meters and a wave period of 7.79 seconds, impacting Burgos, Bangui, and Pagudpud; Osang every 25 years with a maximum significant wave height of 3.77 meters and a wave period of 6.98 seconds near Burgos; Iliang every 50 years a wave height of 5.44 meters and a period of 7.89 seconds near Pagudpud; and Trining every 100 years with a significant wave height of 5.20 meters and a period of 7.92 seconds near Badoc and Pinili. Based on these conditions, recommended seawall heights were calculated, ranging from 7 to 9.4 meters for most areas, with specific variations for each cyclone event. This study highlights the typhoon-induced wave conditions and provides valuable insights for coastal resilience and disaster preparedness in Ilocos Norte.
