This research project aims to establish connections between weather and river flow forecasting, inundation prediction, and the associated risks to people and assets, using the RiskScape platform.
It's official, 2021 was Aotearoa New Zealand’s warmest year on record. The year 2021 finished with an average temperature of 13.56°C in New Zealand, this was 0.95°C above average (relative to the 1981-2010 baseline) and surpassed 2016 to become the country's new warmest year on record.

The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 9 to 12 named TCs could occur in the Southwest Pacific basin between November 2021 and April 2022. The seasonal outlook is for normal to slightly above normal activity in terms of overall named TCs in the region.
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.
El Niño-Southern Oscillation (ENSO) neutral conditions continued during January 2020. The Southern Oscillation Index (SOI) was +0.2, the first positive monthly value since December 2018.
Helping you understand the science of climate change. The things we can do to combat climate change, individually, and alongside our whānau, school and community, can and will make a difference.
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.
NIWA has teamed up with Microsoft for a new project using artificial intelligence to combine historic weather records with breakthrough handwriting recognition tools.
Dr Rob Bell worked out a long time ago that sea-level rise is much more than a scientific problem. No wonder then that people say his ability to listen is one of his best traits.
Temperatures are expected to be near or above average for all regions of New Zealand except the north of the North Island where above average temperatures are most likely.

El Nino –Southern Oscillation (ENSO) neutral conditions continued during December 2019. Both the Southern Oscillation Index (SOI) and sea surface temperatures (SSTs) remained on the El Niño side of neutral but weakened compared to previous months.
ENSO-neutral conditions continued during November 2019, although the Southern Oscillation Index (SOI) dipped into El Niño territory and sea surface temperatures (SSTs) were on the El Niño side of neutral.
NIWA climate scientist Nava Fedaeff presents the NIWA annual climate summary for New Zealand 2019. See the 2019 Annual Climate Summary for all the details.
The weakening of the Southern Annular Mode and the Indian Ocean Dipole and the forecast for ENSO to remain neutral over the next three months indicate the absence of strong, persistent climate drivers for New Zealand.

Across the North Island, moderate to large increases in soil moisture levels were observed in many locations due to substantial rainfall in the past week. Across the South Island, substantial rainfall contributed to moderate to large increases in soil moisture levels in the vast majority of the island.
