Latest status (November 2014)

The sea surface temperature of the central and eastern equatorial Pacific has remained above the normal range for six consecutive months. An El Niño event has been established. Taking into account oceanic observations and the latest forecasts by a number of climate models around the world, El Niño is likely to persist through this winter (Dec 2014 - Feb 2015).
