This research was done to analyse extreme values of significant wave height (????????) in South Eastern Tropical Indian Ocean (SETIO). WAVEWATCH III (WW III) ???????? data for 25 years (1991-2015) with grid resolution of 1/8o and 6 hours time step interval, was used to analyse wave climate and to calculate return values and return periods of extreme ???????? in SETIO with Annual Maximum (AM) and Peak-Over Threshold (POT) method. Based on the the wave climate of ???????? for 25 years, there are high extreme events in open ocean and north part of Australia. The 25, 50, and 75-year return values of extreme ???????? with the AM method have the highest values in the open ocean and the north part of Australia with values around 8 m, about 2 m in protected areas like Padang and NTT, and 4 m in Mentawai, Nias, and south part of Java. The 25, 50, and 75-year return values of extreme ???????? with POT method are around 8 m in the open ocean, 2 m in protected areas, 5 m in Mentawai, Nias, and the south part of Java, and 5 m in the north part of Australia. In general, POT method gives higher value of return value than AM method does for return periods lower than 10 years.
