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.
Analysis of drought conditions across New Zealand this year shows it is one of the most severe on record for some regions.

Annual Climate Summary for 2018

New Zealand’s equal-2nd warmest year on record. Annual temperatures were above average across the majority of New Zealand, including much of the North Island as well as the western and southern South Island. See complete 2018 Annual Climate Summary details.

Weather Tips - What is El Niño?

El Niño. We hear it being brought up in the news quite a bit, but what does it actually mean? No, it's not a type of yoghurt!

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.

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.

This information underpins our knowledge about New Zealand's climate and enables NIWA's science to help New Zealand better manage the impacts of weather and climate on our environment, economy and communities.

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.
A blob of smoke from the Australian bushfires is continuing to circle the globe almost four months after it formed.

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.

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.

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.
One of the top questions NIWA receives about its Seasonal Climate Outlook is: what is below normal / near normal / above average in my region?
Scientists undertaking the annual Southern Alps end-of-summer snowline survey this week will be using advanced photographic technology to help clarify obscure snowlines due to ash and dust from the Australian bushfires.
