Why was 2021 New Zealand’s warmest year on record?

It's official, 2021 was Aotearoa New Zealand’s warmest year on record. The year 2021 finished with an average temperature of 13.56°C in New Zealand, this was 0.95°C above average (relative to the 1981-2010 baseline) and surpassed 2016 to become the country's new warmest year on record.

Tropical Cyclone Outlook: November 2021-April 2022

The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 9 to 12 named TCs could occur in the Southwest Pacific basin between November 2021 and April 2022. The seasonal outlook is for normal to slightly above normal activity in terms of overall named TCs in the region.

Tropical Cyclone Outlook: November 2020-April 2021

The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 8 to 10 named TCs could occur in the Southwest Pacific basin between November 2020 and April 2021. This seasonal outlook is for normal to below normal activity in terms of overall named cyclone systems in the region.

A mild spring, very wet for parts of the North Island

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.
