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.

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. 

2019 New Zealand Climate Summary
NIWA climate scientist Nava Fedaeff presents the NIWA annual climate summary for New Zealand 2019.
During May the NINO3.4 Index anomaly (in the central Pacific) for May was +0.01˚C, with upper oceanic heat content continuing to decrease across the equatorial Pacific.
Oceanic ENSO-neutral conditions will very likely persist over the next three months. The long-standing climate drivers that have contributed to dryness over much of NZ are expected to influence our weather for at least the first half of the winter season.
El Niño Southern Oscillation (ENSO) neutral conditions continued during April 2020. The Southern Oscillation Index (SOI) was +0.1.
This is one of the most extreme drought events for Auckland in modern times and similar to one experienced in 1993/94.
Seven weeks of lockdown has provided evidence of how pollution can vanish overnight with benefits for the environment and individuals, says NIWA air quality scientist Dr Ian Longley.
Please note that this will be the final Hotspot Watch update for this season. Weekly Hotspot Watches will return in the spring.
For more than a century, a network of volunteers across New Zealand have been measuring the climate and weather and sending their observations each month to be entered into the New Zealand climate database.
Very dry for many parts of New Zealand.
Analysis of drought conditions across New Zealand this year shows it is one of the most severe on record for some regions.
Sharp cold snaps are possible during the month of May as fronts move onto the country from the Tasman Sea and Southern Ocean.
Moderate soil moisture increases in the western North Island and in the Far North, while soil moisture decreases were observed along the east coast and Wairarapa. Many parts of the South Island saw small soil moisture increases during the past week, although small decreases were observed in northern Canterbury.

High waves pounding Wellington’s south coast today are being caused by a deep area of low pressure passing the Chatham Islands, according to NIWA forecaster Ben Noll.
El Niño Southern Oscillation (ENSO) neutral conditions continued during March 2020. The Southern Oscillation Index (SOI) was 0.5.
El Niño Southern Oscillation (ENSO) neutral conditions continued during February 2020. The Southern Oscillation Index (SOI) was 0.2.
The New Zealand Drought Index shows that severe meteorological drought remains across the Coromandel Peninsula and near Cape Reinga. Meteorological drought is found across parts of the Far North, Auckland, and far northern Waikato
Dry for many locations; temperatures near to below average
In the North Island severe meteorological drought coverage has again receded significantly in the past week, although it is still widespread in the Coromandel Peninsula. Meteorological drought remains in place across parts of Northland, Auckland, northern Waikato, and East Cape. Meteorological drought has completely dissipated across the upper South Island, although widespread dry soils are still present.
Warmer than average ocean waters in the Coral Sea and west-central Pacific Ocean are expected to have some influence on New Zealand’s climate in the first half of the three month period.

NIWA climate scientists are asking for volunteers to help give its historic weather project a quick, sharp boost.
Across the North Island, rainfall during the past week was quite variable. Moderate rainfall occurred in the West Coast and Southland. However, rainfall was generally meagre from Marlborough to southern Canterbury.
Across the North Island, rainfall during the past week was generally higher than several previous weeks, with many locations receiving 10-20 mm and isolated pockets of 30 mm or more.
