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.
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.
Oceanic ENSO-neutral conditions will very likely persist (71% chance) over the next three months. The long-standing climate drivers that have contributed to dryness over much of New Zealand are expected to influence our weather for at least the first half of the winter season. Air temperatures are most likely to be above average in the east of the South Island and about equally likely to be near average or above average in all other regions.
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.
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 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.
The New Zealand Drought Index shows that severe meteorological drought remains across the Coromandel Peninsula and near Cape Reinga. Meteorological drought is found across parts of the Far North, Auckland, and far northern Waikato
