El Niño-Southern Oscillation (ENSO) has important roles to play in relation to Southeast Asian rainfall anomalies. The observation of ENSO impact on Sea Surface Temperature (SST) has relationship with rainfall variability in Thailand. The data is SST of NOAA-Pathfinder satellite dataset. Data of ENSO represent by Niño3 and Niño3.4 index, while the rainfall data used APHRODITE’s and the data from Thai meteorological department 26 stations. The rainfall variability over Thailand was analyzed by using empirical orthogonal function (EOF) analysis and the relationship between Niño3, Niño3.4 SST index and principal component time series (PC’s) of seasonal rainfall in Thailand is calculating by Pearson’s correlation. The result show the Niño3.4 SST index is mostly correlation to the MAM season of rainfall over Thailand. The correlation is negative, because a high SST anomaly gives a low rainfall anomaly, and a low SST anomaly gives a high rainfall anomaly.
