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.

Our work

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.

NIWA’s research into forecasting weather systems aims to increase the resilience of New Zealand communities to weather-related hazards.

Glacier melt: A Time Capsule

Since 2016 enough ice has melted from the South Island’s Brewster Glacier to meet the drinking water needs of all New Zealanders for three years.

Tropical Cyclone Outlook: November 2020-April 2021

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 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.

Temperatures are most likely to be above average in the west and east of the South Island and about equally likely to be above average or near average in all other regions. While cold spells and frosts will occur, as is typical during winter, they may be infrequent.
NIWA forecasters say expected clear skies are looking good for spotting the Super Blood Moon on Wednesday night.

We combine capabilities in weather, storm surge and tide forecasting with tide gauge observations to predict sea levels for specific locations under forecast weather conditions.
The NINO3.4 Index anomaly (in the central Pacific) during April was -0.30⁰C and the SOI (Southern Oscillation Index) was +0.3, both within the neutral range.
A Central Otago scientific research station with a globally revered reputation is marking its 60th anniversary.
Warmer and drier than normal for many
Temperatures are very unlikely to be colder than average for the three months as a whole. Above average or near average temperatures are favoured for all regions except the east of the South Island, where above average temperatures are most likely.
When high winds on the Auckland Harbour Bridge last September caused two trucks to topple over, one into a load-bearing strut, NIWA scientists began thinking about what role they could play in preventing it from happening again.
