One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.
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.
Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.
Our Future Climate New Zealand is an interactive website that lets you to look at projections for a number of climate variables for New Zealand between now and 2100.
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 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.
During autumn, New Zealand’s climate patterns are expected to become more variable as the impact from a non-traditional central Pacific La Niña starts to ease.

Temperatures are most likely to be above average in the north of the North Island and about equally likely to be near average or above average in all other regions.

The NINO3.4 Index anomaly (in the central Pacific) for the last month (through the 3 rd of January) was 0.84˚C, increasing from 1.03˚C from last month.
Sub-tropical air flows may fuel areas of localised, heavy rainfall that can cause flooding, similar to what was in experienced in parts of the country during late December and early January.
A vital network of rainfall and climate station volunteers across Aotearoa send their weather measurements to NIWA every month where they are used by scientists researching New Zealand’s climate.
In a year that has brought us a bit of everything weather-wise, we’re happy to report that Aotearoa will be on Mother Nature’s good side this holiday period — mostly.

Significant rainfall amounts of 30-70 mm occurred in western Waikato, Taranaki, Wairoa District, and Wellington, during the past week, with a few locations in these areas receiving up to 100 mm.
