Abstract: Wave climate and wave energy in Hikkaduwa on the south-western coast of Sri Lanka were successfully simulated by using MIKE 21 Spectral Wave Model. To hindcast, the wave climate in the study area, directional global offshore wave data hindcast at 3000 m depth for the period of January 2010–June 2020 was transformed into the study area by using numerical simulation techniques. Thus, a representative nearshore wave climate was established at 15 m water depth in the study area on an annual and seasonal basis. Southwest monsoon was identified as the dominant season for wave characteristics. A higher percentage of waves approach from the 210°–230° N directional range during the southwest monsoon. Based on the identified dominant wave characteristics, configurations of the proposed redeveloped harbour at Hikkaduwa were conceptually recommended. The nearshore area of the study area was identified as a possible site for wave energy extraction.
