As of the October 2009 report, NCEI will no longer write a separate assessment of the current state of El Niño/Southern Oscillation as part of its Monthly Climate Report. This information will be incorporated in the El Niño Diagnostic Discussion produced each month by the NOAA Climate Prediction Center.

Current and historical values of ENSO indicators and further information can be found at NCIE's El Niño/Southern Oscillation (ENSO).

Thank you for your interest in NCEI products.
