Atmospheric and oceanic anomalies in the equatorial Pacific reflect strong El Niño conditions. Sea surface temperature anomalies in the central and eastern Pacific have increased since September and are close to or exceed +2.5oC in places, whereas sub-surface temperature anomalies exceed +6oC in the far eastern tropical Pacific.
November 2015 - January 2016 temperatures are equally likely to be average (40% chance) or below average (40% chance) for the north and east of the North Island, and most likely to be near average (45% chance) for the east of the North Island and north of the South Island.
During August – October 2015, above normal pressure was forecast over and to the south of Australia, while below normal pressure was expected well to the northeast of New Zealand.
