Tropical Pacific Ocean sea surface temperatures have persisted at ENSO neutral values for several weeks. Below the surface, much of the tropical Pacific is now at near average temperatures. Atmospheric indicators are also generally at neutral ENSO levels. The Southern Oscillation Index (SOI) is close to zero, while trade winds are currently being enhanced by the Madden Julian Oscillation (MJO). Only cloudiness near the Date Line continues to show a weak La Niña like signature.
