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!

NIWA climate scientists are calling for volunteers to unearth weather secrets from the past – including those recorded by members of Captain Robert Scott’s doomed trip to the South Pole in 1912.
Southwest Pacific Tropical Cyclone Outlook: Near-normal tropical cyclone activity overall during November-April, but increased east and reduced west of the Date Line; multiple severe tropical cyclones expected.
A wet start to spring for some but dry for most
The consensus from international models is for the tropical Pacific to transition toward El Niño over the next three-month period (68% chance over October – December 2018). The probability for El Niño conditions being established remains high until autumn 2019, with a 71% chance for El Niño conditions over the April – June 2019 period.
A NIWA-led team has today been awarded a multi-million dollar research grant that will help drive major advances in understanding of New Zealand’s carbon emissions and uptake
A cool start to spring is about to be replaced by a sudden burst of warmth, according to NIWA meteorologist Ben Noll.
ENSO-neutral conditions continued across the tropical Pacific during July 2018. The Southern Oscillation Index (SOI) was in the neutral range, with a preliminary value of +0.2 for July 2018. Surface ocean waters in the central and eastern equatorial Pacific continued to warm during July but remained in the neutral range. The subsurface ocean remained warmer than average in the eastern equatorial Pacific during July, but anomalies weakened slightly compared to June.
It's a story of the warm and the wet.
A dry start to winter for much of the South Island.
El Nino – Southern Oscillation (ENSO) neutral conditions continued across the tropical Pacific during June 2018. The Southern Oscillation Index (SOI) was slightly negative at about -0.7 during the past 30 days (on the El Niño side of neutral). The central equatorial Pacific experienced warming sea surface temperatures (SSTs) for the third consecutive month and was slightly above average for the time of year.
Spare a thought for Fieldays exhibitors putting the final touches to their stands tomorrow – it’s going to be wet.
A warm start to autumn, then cooler and unsettled at times.
Warm and dry to start, followed by cooler and unsettled conditions.
ENSO-neutral conditions persisted in the tropical Pacific during May 2018. The Southern Oscillation Index (SOI) was positive at about +0.3 during the past 30 days. Sea surface temperatures (SSTs) in the central and eastern equatorial Pacific Ocean warmed for the second consecutive month and are now near or slightly above average for the time of year.
We've got hot temperatures, we've got cold temperatures, freezing temperatures, ice, snow, hail, rain - and even a few rays of sunshine. And one very confused weather pattern.
What happened in April, how our climate outlook for the previous three months turned out, global and local sea temperatures, and our outlook for May-July.

How a regional climate history helped save a farm and cure depression
Weak La Niña conditions continued in the tropical Pacific during March 2018, but trends in low-level winds and in sub-surface ocean temperatures during the month indicate that the event is coming to an end.
New Zealand is situated in the latitudes of prevailing westerlies and exposed coastal locations often experience strong winds, with generally lighter winds elsewhere.
