N2  - The 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
