Global Setting – December 2012
The equatorial Pacific Ocean reflects ENSO-neutral conditions (neither El Niño nor La Niña). Global guidance indicates that these neutral conditions are very likely to persist into the Southern Hemisphere autumn. For the New Zealand region over the coming three months (January-March 2013), lower than normal pressures are expected in the south Tasman Sea and to the southeast of the Chatham Islands, with enhanced south-westerly winds over the country.
Sea surface temperatures
Sea surface temperatures around New Zealand are expected to remain close to average overall over the late-summer period.
