Abstract: The need of alternative sources of energy is highly prioritized following the declination of fossil fuels. The highly dynamic ocean which covers more than 70% of the earth surface can certainly be a promising target to serve for such a need. In this study, the potential of wave power in Thailand is investigated. Hourly wave data available at 18 locations along both of the national coastlines were processed to disclose that the power at each location could sometimes be as high as 20 to 50 kW. The locations with wave fetches on their west, including all in Andaman Sea, see the peak power in May to October during the southwest monsoon season. Most locations in the Gulf of Thailand feature intensive wave power in November to March during the northeast monsoon. A statistical analysis was performed to examine the distribution of annual wave power which, for the locations with western wave fetches, follows the Weibull probability density function. For the other group of locations, the frequency-magnitude relationship of wave power tends to resemble a log-normal distribution. The fractions of annual power contributed by waves from different seasons were quantified to confirm that only the monsoon waves should be prioritized as mostly beyond 80% of the total annual power belonged to them. Important findings in this study provide an outlook for wave power potential in Thailand where not only the intensity but also the fluctuation needs to be critically concerned.
