El Niño/La Niña Update (May 2019)

Sea surface temperatures in the tropical Pacific have generally been at borderline to weak El Niño levels since October 2018. However, it was not until February that some atmospheric indicators reacted to these warmer than average sea surface temperatures. WMO Global Producing Centers of Long Range Forecasts predict ocean temperatures to remain close to current levels through the June-August period, but may ease in September-November.
