El Niño and La Niña
Latest status (November 2016)

In the past month or so, sea surface temperatures of the central and eastern equatorial Pacific continued to cool. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the cooling trend is expected to persist in winter 2016/17 (December 2016 – February 2017), indicating that La Niña may start to develop.
