Climate & Weather

Understanding our variable and changing climate is critical for managing resources and reducing risks.

  • Improving seasonal climate forecasts

    Feature story
    NIWA’s climate scientists are working to improve seasonal climate forecasts.
  • NIWA's Hotspot Watch

    Hotspot
    A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent.
  • Meeting the challenge of ocean acidification

    Feature story
    New Zealand’s answer to ocean acidification is a model of the ‘best team’ approach – when organisations pool talent and resources to find solutions to national, or global, issues.]

  • NIWA's Hotspot Watch

    Hotspot
    Over the past week, soil moisture levels across the North Island have mostly remained the same or increased.
  • Field work and collections

    Climate Present and Past is involved with maintaining nationally important collections and undertaking field work.
  • Extremes

    Although New Zealand is located in a temperate region, the country still experiences extreme climatic conditions from time to time.
  • Trends

    The Earth’s climate experiences changes caused by natural fluctuations as well as human influences. These result in trends over time for different climatic variables.
  • Synoptic types

    New Zealand is affected by weather systems which originate over the seas around the country, which can be characterised as 12 daily weather types.
  • ACRE Antarctica

    ACRE Antarctica is a project within the Deep South National Science Challenge.
  • ACRE Pacific

    ACRE Pacific is a NIWA-led part of the the wider ACRE initiative, run by the UK Met Office.
  • PICT (Past Interpretation of Climate) tool

    The Past Interpretation of Climate Tool (PICT) is an interactive platform that "allows palaeoclimate researchers to interpret data in terms of atmospheric circulation (AC) patterns and how those patterns relate to synoptic weather types".
