ENSO Status:

The Climate Prediction Center defines El Niño conditions as existing when a one-month positive sea surface temperature anomaly of 0.5C or greater is observed in the Niño-3.4 region of the equatorial Pacific Ocean, an expectation that the 3-month Oceanic Niño Index (ONI) threshold will be met (see graphs below), and
 an atmospheric response typically associated with El Niño is observed over the equatorial Pacific Ocean. Please visit the Climate Prediction Center website for El Niño status and predictions.
