Final Hotspot Watch update for this season. Weekly Hotspot Watches will return in the spring.
A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

Scientists undertaking the annual glacier snowline survey over the South Island later this month are keeping a watchful eye on a lake that has been forming and disappearing at the junction of the Tasman and Hochstetter glaciers.

Our work

NIWA’s research into forecasting weather systems aims to increase the resilience of New Zealand communities to weather-related hazards.
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.
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.
Does climate change affect the position of the Subtropical Front around New Zealand? This has important consequences for New Zealand's climate and biological productivity.

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.

During September, the NINO3.4 Index anomaly (central Pacific) was 0.71˚C. The NINO 1+2 Index (eastern Pacific) was 0.76 C.
Dry for northern North Island, wet for much of South Island.
Air pressure is forecast to be higher than normal to the southeast and lower than normal to the north of New Zealand. This is expected to be associated with developing La Niña-like northeasterly air flow anomalies, although a westerly flow anomaly, which may be strong at times, is favoured to continue for much of October.
NIWA environmental monitoring technician Mike O’Driscoll has just installed two water level stations in Samoa and is starting on a third—all from the comfort of his Greymouth office.

A new study has identified seven freshwater species native to Aotearoa-New Zealand that will likely be highly or very highly vulnerable to climate change.
New Zealand’s warmest winter on record.
A warm and dry finish to winter.
During August, the NINO3.4 Index anomaly (in the central Pacific) was 0.42˚ C. The NINO 1+2 Index (eastern Pacific) was 0.85 C.
September – November 2020 air pressure is forecast to be higher than normal to the east and lower than normal to the northwest of New Zealand. This is expected to be associated with La Niña-like northeasterly air flow anomalies.
NIWA is using serious games to look at problems holistically, support understanding and give a framework for climate change adaptation decision-making.
NIWA’s South Island snow and ice monitoring stations have confirmed what many skiers have been talking about: winter has been dry and snow coverage has been poor. In fact, several sites have recorded half their typical snow depth for this time of year.
NIWA works with businesses, organisations, and central and local government to help them understand their climate risks, plan for adaptation, and meet the regulatory requirements for the Taskforce on Climate-related Financial Disclosures (TCFD).
If we can understand how the Earth’s climate has changed in the past, we can use that information to understand how it might change in the future.
Were there any terms you didn't know in any of these lessons? We explain some of them here - alphabetically from anemometer to wind speed.
