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 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.
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 July, the NINO3.4 Index anomaly (in the central Pacific) was +0.04˚C. The NINO 1+2 Index (eastern Pacific) was 0.72 C, decreasing from 0.57 C in June.
During periods of northeasterly winds, the threat for sub-tropical low pressure systems capable of producing heavy rainfall, similar to those experienced in late June and mid-July, is elevated, particularly in the north and east of the North Island.
Some of the most striking images of lockdown around the world have been the blue skies of cities ordinarily choking in smog. From New Delhi to Los Angeles, Beijing to Paris, the changes were so remarkable they were visible from space.
During June, the NINO3.4 Index anomaly (in the central Pacific) was 0.12˚C. Upper oceanic heat content decreased notably across the east central equatorial Pacific.
Rainfall is about equally likely to be near normal or below normal in the west of the South Island, about equally likely to be near normal or above normal in the east of the North Island, and most likely to be near normal in all other regions.
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.
Developed for teachers, these lessons offer intermediate age students an engaging and interactive way to learn about Aotearoa’s wild and mild weather and climate patterns.
