Climate & Weather

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

  • NIWA's Hotspot Watch for 23 November 2017

    Hotspot
    A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
  • The Stormy Seas project

    Research Project
    Does climate change affect the position of the Subtropical Front around New Zealand? This has important consequences for New Zealand's climate and biological productivity.

  • Winters much shorter than they once were, says NIWA

    Media release
    New Zealand winters are a month shorter than they were 80 years ago, NIWA scientists say.“This is a consequence of rising temperatures around the globe, and such trends in colder temperatures and frosts will influence the life cycle of plants and animals” - Dr Brett Mullan.

  • Extended warmth for South Island

    Media release
    A large area of high pressure will take up residence east of New Zealand for the next few days, bringing more unusual springtime warmth to parts of the South Island from tomorrow through to late next week, says NIWA forecaster Seth Carrier.
  • NIWA's Hotspot Watch for 26 October 2017

    Hotspot
    A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Across the North Island, soil moisture levels have generally not changed significantly during the past week, while across the South Island, soil moisture levels have generally decreased.
  • Southern spring sizzle sets records

    Media release
    An immense dome of high pressure stretched across the Tasman Sea onto the South Island yesterday, bringing the highest temperatures across New Zealand since April.
  • NIWA's Hotspot Watch for 19 October 2017

    Hotspot
    The first weekly update for the 2017-18 summer describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent.
  • Dramatic sea ice decline limits NIWA’s Antarctic research

    Media release
    A dramatic change in sea ice this year is likely to hamper a NIWA-led research project aiming to better understand how ice shelves will melt as the ocean warms.
  • Southern spring sizzle

    Media release
    An air flow extending from Australia on Thursday and Friday may bring near-record warmth to parts of the interior South Island, says NIWA forecaster Ben Noll. A large area of high pressure to the northwest of New Zealand will help steer this warm air across the Tasman Sea.
