Conversely, during the La-Nina phase, wave heights increased, especially at stations 2 and 3, showing a stronger positive correlation. The relationship between SOI and SWH varied depending on location and time period. This study concludes that ENSO has a significant impact on the variation in wave heights in the waters of North Halmahera and Morotai.
