If Santa is quick he can hop on a ridge of high pressure for his big trip to New Zealand very soon.
Across the North Island, notable increases in soil moisture levels were observed in the southwest, from Taranaki south to Wellington.
Across the North Island, notable decreases in soil moisture levels were observed from Northland to Waikato, including the Coromandel Peninsula.
New Zealand has just experienced its hottest November on record, according to NIWA climate scientists.

Our work

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.

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.

Across the North Island, notable increases in soil moisture levels were observed in the southwest, from Taranaki south to Wellington.
NIWA's 2020 storm-tide red alerts are the highest high tide (also known as king tides) dates that Emergency Managers and Coastal Hazard Managers should write in their diaries and keep an eye on adverse weather (low barometric pressure, onshore winds), river levels and sea conditions (waves and swell).
Across the North Island, notable decreases in soil moisture levels were observed from Northland to Waikato, including the Coromandel Peninsula.
Hottest November on record for New Zealand
Warmest recorded November closes 12th warmest Spring
New Zealand has just experienced its hottest November on record, according to NIWA climate scientists.
Temperatures for the summer season are expected to be above average for New Zealand, apart from the west of the South Island where there are about equal chances for near average or above average temperatures.
Across the North Island, soil moisture levels decreased island-wide during the past week due to meagre rainfall and above average temperatures.
Novel handwriting recognition project casts new light on historic weather data.
Across the North Island, soil moisture levels increased in many places during the past week. In the South Island, soil moisture levels generally decreased in the east and a slightly increased in the west.
Variable rainfall patterns; cool in the lower South Island.
We seek a highly motivated person for a three-year PhD studentship on measurements and modelling of atmospheric greenhouse gases at the National Institute of Water and Atmospheric Research (NIWA) in New Zealand.
NIWA and MetService analyses indicate 9 to 12 named tropical cyclones (TC) could occur in the Southwest Pacific basin between November 2019 and April 2020. This expectation for tropical cyclone activity is close to normal for the region, but with elevated activity east of the International Date Line especially during the late season between February and April.
Average temperatures overall with variable rainfall patterns.
For October to December, air pressure is forecast to be lower than normal in the New Zealand region, especially south of the country. This is expected to be associated with a westerly quarter air flow anomaly, particularly during November and December. Occasional easterly quarter winds are possible during October.
Expect to hear a lot more about climate change in the news in the weeks ahead – and a lot about NIWA’s work underpinning the science that is signalling a warmer world right now and its effects in the future.
Variable temperature and rainfall patterns with frequent southwesterly winds.
7th-warmest winter on record and near normal rainfall
The central Pacific El Niño event that arrived in March 2019 has ended, giving way to ENSO neutral conditions, owing to cooling sea surface temperatures (SSTs) in the tropical Pacific and a neutral Southern Oscillation Index (SOI) during August.
NIWA meteorologists are keeping an eye on an unusual atmospheric phenomenon that is amassing in the polar stratosphere.
New Zealand’s 2nd-warmest July on record.
Despite a sharp cold snap in early August, seasonal temperatures are forecast to be near average or above average for all regions of New Zealand, owing to warmer than average coastal and regional sea surface temperatures.
An unusually dry start to winter.
