Summary for New Zealand

El Niño Advisory: El Niño conditions are present.

There is an approximately 50-60% chance that El Niño conditions will continue through Southern Hemisphere winter 2015.

April Temperature

North Island: Most of the island is expected to be above normal except for the Southern Hawkes Bay which will be near normal.

South Island: Large areas of the island are forecast to be slightly to moderately warmer, especially the Alps and eastern part of the island, except for South Canterbury which should be near normal.

April Precipitation

North Island: Much of the island is forecast to be drier than normal with Auckland and Southern Northland and East Cape down to Hawkes Bay moderately to drier than normal. Only Auckland, Southern parts of Northland, Hawkes Bay and Gisborne areas are expected to be moderately drier than normal along with the East Cape.

South Island: Only slightly drier conditions are expected in the west. While much of the east will be near normal and with parts of inland Southern Canterbury could be moderately drier than normal while parts of southern Otago could be slightly wetter than normal.

April Potential Evapotranspiration Deficit

North Island: The entire island is either close to normal or in deficit especially the East Cape and Northern Hawkes Bay and eastern coastal parts of Northland.

South Island: The West Coast dries out along with the Alps while the East Coast improves its deficits to be near normal to only slight deficits.

May Temperature
