Global Setting – March 2013
The equatorial Pacific Ocean remains in a neutral state (neither El Niño nor La Niña). International guidance indicates that neutral conditions are very likely to continue over the next three months (April–June). In the New Zealand region higher pressures are likely to prevail over and to the south of the South Island during the season.
Sea Surface Temperature
Sea surface temperatures in late autumn are likely to remain above average around the South Island, and be close to normal around the North Island.
