El Niño/Southern Oscillation - October 2009

As of the October 2009 report, NCDC 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, along with values of other teleconnection indices, can be found at: http://www.ncdc.noaa.gov/teleconnections/

Thank you for your interest in NCDC products.
