Latest news

Among the multitude of New Zealand climate statistics there is one record that continues to be broken month after month.
Scientists analysing end-of-summer snowline survey photos have estimated that 13 million cubic meters of ice have been lost from just one glacier from 2016 to 2019.
This is one of the most extreme drought events for Auckland in modern times and similar to one experienced in 1993/94.
Seven weeks of lockdown has provided evidence of how pollution can vanish overnight with benefits for the environment and individuals, says NIWA air quality scientist Dr Ian Longley.

Annual Climate Summary for 2018

New Zealand’s equal-2nd warmest year on record. Annual temperatures were above average across the majority of New Zealand, including much of the North Island as well as the western and southern South Island. See complete 2018 Annual Climate Summary details.

How a regional climate history helped save a farm and cure depression
Weak La Niña conditions continued in the tropical Pacific during March 2018, but trends in low-level winds and in sub-surface ocean temperatures during the month indicate that the event is coming to an end.
New Zealand is situated in the latitudes of prevailing westerlies and exposed coastal locations often experience strong winds, with generally lighter winds elsewhere.
Sea surface temperatures in the southern Tasman Sea rose to exceptionally high levels in late 2017 and early 2018. These temperatures were far above any others previously observed at that time of year in the region, and extended west from New Zealand to Tasmania and mainland southeast Australia.

Twice a day at 1pm and 8.30 pm Sean Hartery, NIWA, and Peter Kuma, University of Canterbury, head for the Fantail at the very back of the ship to release their weather balloons.

Climate scientists and glaciologists are taking to the skies this week to find out how New Zealand’s glaciers are faring following this summer’s record-breaking warmth.
Two ex-tropical cyclones impact New Zealand
New Zealand's hottest summer on record.
With La Niña’s influence waning over the next three month period, New Zealand’s regional climate over March – May 2018 is expected to be driven by the warmer than average ocean waters that are present around the country.
Despite a sub-tropical storm and two ex-tropical cyclones, this summer is about to become the hottest in history.
Auckland region climate change projections and impacts | Auckland Council

Auckland Council and Council Controlled Organisations commissioned NIWA to provide climate change projections, including high-resolution maps for the Auckland Region.

Apart from waning La Niña conditions, New Zealand’s regional climate over the next three month period is expected to be dominated by the very warm ocean waters present around the country, in the Tasman Sea, and in the Southwest Pacific Ocean.
January 2018 was New Zealand’s hottest month on record (since 1909) using NIWA’s seven-station series. Dozens of locations observed their record or near-record high mean temperature for January.

A very warm and dry month
A year of weather extremes across New Zealand
Four seasons with a little bit of everything. It started with the bummer summer… then came the fires, rain, flooding and a very weird November. But it’s all in a year of weather as NIWA wraps up the seasonal highlights.
