Latest news

NIWA researchers have helped unlock information trapped in ancient air samples from Greenland and Antarctica that shows the amount of methane humans are emitting into the atmosphere from fossil fuels has been vastly underestimated.
Nearly all of the North Island has reached official hotspot status, with only a few isolated areas that have not quite reached hotspot criteria. Current hotspots in the South Island now include Nelson and nearby parts of Tasman, much of Marlborough, along with northern Canterbury, Banks Peninsula, and parts of Ashburton and Selwyn districts.
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 has teamed up with Microsoft for a new project using artificial intelligence to combine historic weather records with breakthrough handwriting recognition tools.

2019: New Zealand’s 4th-warmest year on record
In the past 10 years, more weather records have been broken than in any other time in New Zealand’s history.
Across the North Island, moderate to large increases in soil moisture levels were observed in many locations due to substantial rainfall in the past week. Across the South Island, substantial rainfall contributed to moderate to large increases in soil moisture levels in the vast majority of the island.

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.
