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 forecasters say a marine heatwave is forming around parts of New Zealand after sea surface temperatures (SSTs) warmed considerably last month.

In the North Island, moderate rainfall amounts of generally 25-50 mm occurred across much of Northland and Auckland during the past week, with generally 15-30 mm for much of the western North Island and the western Wellington Region. Conversely, the east coast (including Wairarapa) saw generally light rainfall amounts.

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.

Sometimes wind can feel like a bit of a mystery because we can feel it, but not see it.
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.
Warm start to winter for much of the country
Among the multitude of New Zealand climate statistics there is one record that continues to be broken month after month.
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.

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.
Trade winds during April were slightly stronger than normal along the equator. This pattern is expected to continue over the next 1 2 months, most likely leading to continued cooling in the west central Pacific.
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.

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.
