Indonesia is an important site for climate studies, because of it-s located between Indian and Pacific oceans. Climate phenomena which is happened in the Pacific and Indian oceans i.e El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) influence Indonesian climate. To understand behaviour of climate phenomena and its impact to Indonesian climate it is required paleoclimate data which provide long time series climate data back to hundred till thousands year. Sea surface temperature is one of important climate parameter. Coral Sr/Ca is convinced as coral paleo-thermometer. In this study, the available coral Sr/Ca is used to reconstruct past SST variability (Coral SST). The variability of coral SST from several sites in Indonesia waters is investigated and compared between sites. The coral SST is also correlated with the Nino 3.4 and IOD indices to know how the climate phenomena influence the SST variability. The result shows that the influence of IOD and ENSO difference between sites. Some sites e.g Seribu island coral SST shows that SST is influenced by IOD rather than ENSO, while from Timor coral SST shows that shows that Indian Ocean Dipole (IOD) influences SST and SSS while ENSO only influences SST
