The Philippines emerged as a promising site for wave energy harvesting, considering significant wave height and wave period. A comprehensive assessment was conducted of potential ocean wave energy sites along the Philippine coastline specifically in Baler, Aurora by integrating data from Jason-2 and 3 satellite altimeters, SWAN model simulations, and in-situ measurements, utilizing Matlab and SWAN software. Rigorous validation methodologies were emphasized to ensure data accuracy through validation with in-situ measurements. The study revealed the influence of monsoon seasons on wave energy potential, offering insights into seasonal variations. Despite reduced energy potential during the westerly monsoon, significant wave energy during the easterly monsoon remained attractive. Maximum energy could be harnessed with a significant wave height of 2.5–3.0 m and a wave period of 7–8 s. These findings contribute to understanding site selection criteria, potential estimation, and methodologies in wave energy generation.
