Climate & Weather

This five-year NIWA-led research programme is developing a system to map flood hazard consistently across the whole country. It will reveal how our flood risk might change over the next 100 years because of changes to rainfall and sea level from climate change, as well as due to land-use changes.

NIWA’s research into forecasting weather systems aims to increase the resilience of New Zealand communities to weather-related hazards.

NIWA Weather is NIWA's public facing weather forecasting website.

This Toolbox helps you find out about the changing climate, what it might mean for your business, organisation or community.

Hottest, coldest, wettest, driest, sunniest, windiest...which places hold the record for climate extremes in NZ?

Air temperature, rainfall, soil moisture and river flow predictions for the coming season.

Regional-scale climate projections assist local authorities to assess climate risks and help communities prepare for impacts.

Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.

NIWA's long-running 'seven-station' series shows NZ's average annual temperature has increased by about 1 °C over the past 100 years.

NIWA are developing a modelling approach to better predict fish abundances in the past, to then be able to forecast fish abundances in the future under climate change and fishing scenarios

When will I be able to see Matariki rising?
