NIWA Climate Change Maps
NIWA’s National Climate Centre has produced a set of five A1-size maps displaying some of our new climate change projections for New Zealand.
The maps present a ‘middle-of-the-road’ picture of the future.

Rainfall in September was below normal for many areas, particularly in parts of Northland, Auckland, Waikato, Coromandel, and the east coast of the North Island, but 150% or more above normal in parts of the South Island.
September temperatures were more than 1.5 °C above their normal values in South Canterbury and Central Otago, and above normal in many other places.

Global setting and climate outlook
El Niño-Southern Oscillation remains neutral despite positive SOI

Neutral ENSO conditions in the tropical equatorial Pacific are now well established, although lingering effects of La Niña persist. The Southern Oscillation Index remains positive, having strengthened somewhat during September to +1.4 with the three-month mean at +0.8. The positive sea surface temperature anomalies in the eastern Pacific reduced during the month.
