Without the global CFC ban we’d already be facing the reality of a “scorched earth”, according to researchers measuring the impact of the Montreal Protocol.
NIWA is leading a New Zealand partnership to map the South and West Pacific Ocean's seabed as part of a worldwide initiative to map the entire globe’s seafloor.
Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.
Our Future Climate New Zealand is an interactive website that lets you to look at projections for a number of climate variables for New Zealand between now and 2100.
The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 8 to 10 named TCs could occur in the Southwest Pacific basin between November 2020 and April 2021. This seasonal outlook is for normal to below normal activity in terms of overall named cyclone systems in the region.
The NINO3.4 Index anomaly (in the central Pacific) during August was -0.17 ̊C. The Southern Oscillation Index was +0.5. While both remained in neutral territory, other indicators trended toward La Niña.
Spring rainfall is most likely to be below normal in the east of the North Island, near normal in the west of the South Island, and about equally likely to be near normal or below normal in all remaining regions across Aotearoa New Zealand.

New Zealand has just experienced its warmest June and July since records began in 1909 and – with one month to go - is on track for its second successive warmest winter on record.
Temperatures are most likely to be above average in all regions of the country. More northwesterly air flows will likely cause spells of unseasonably warm temperatures in the north and east of both islands in particular.
The NINO3.4 Index anomaly (in the central Pacific) during June was 0.18 ̊C, the first time it has been positive since July 2020. The Southern Oscillation Index was +0.4, in the ENSO neutral range.
NZ’s weather patterns are expected to feature substantial week-to-week variability over the coming months, owing to an ENSO neutral state in the tropical Pacific Ocean.
Preliminary analysis by NIWA climate scientists has shown that the recent Canterbury rainfall was so extreme in some inland places that it could be expected to happen only once every 200 years.
Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.
Farmers visiting NIWA’s Fieldays stand at Mystery Creek next week have the opportunity to see into their future by playing a game that dices with climate change.
The prodigious rainmaker that hit Canterbury earlier this month saw NIWA field teams out in the elements collecting flood data from bridges, cableways and jetboat gaugings.
The NINO3.4 Index anomaly (in the central Pacific) during May (through the 30th) was -0.11˚C, the smallest anomaly since July 2020. The Southern Oscillation Index (SOI) was +0.5, in the ENSO neutral range.
