Monthly OISST.v2 (1981-2010 base period) Niño 1+2 (0-10°South)(90°West-80°West) Niño 3 (5°North-5°South)(150°West-90°West) Niño 4 (5°North-5°South) (160°East-150°West) Niño 3.4 (5°North-5°South)(170-120°West):

NOTE: Please note this file has been reduced to January 1982, which is when the OISSTv2 dataset begins. This file will continue to be updated each month in real-time. The COADS data prior to January 1982 is no longer updated in real-time. If you are interested in historical data prior to January 1982, then a monthly ERSST.V3B Niño index file is linked below (this file will also be updated in real-time once a month).
