” The tropical Pacific has remained neutral with respect to the El Niño–Southern Oscillation (ENSO) since mid-2012. All the main ENSO indicators remain well within neutral bounds; for example, sea surface temperatures in the tropical Pacific are very close to their long-term average.
International climate models surveyed by the Bureau of Meteorology indicate the persistence of this neutral ENSO phase through at least the austral autumn. This would then mean the tropical Pacific would have been neutral (i.e. in neither El Niño nor La Niña territory) for approximately two years.
The Indian Ocean Dipole is currently neutral. It typically does not influence the Australian climate during the months from December to April. “
