Climate & Weather

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

  • NIWA's Hotspot Watch for 29 March 2019

    Hotspot
    Hotspots continue to be found across a large part of Northland, Auckland, northern Waikato, and interior Bay of Plenty, as well as central Manawatu-Whanganui and Napier south to Wairarapa. South Island hotspots are currently located in a portion of interior Marlborough, eastern Banks Peninsula, south coastal Otago and parts of lower Southland.

    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.
  • International climate experts gather in Wellington

    Media release
    Weather and climate experts from around the world are meeting in Wellington next week to discuss the critical need for accurate forecasting to cope with a changing climate.

  • NIWA's Hotspot Watch for 20 February 2019

    Hotspot
    Areas deemed hotspots now encompass large portions of the entire North Island. Hotspots remain entrenched across the northern tier of the South Island, including across northern Tasman, Nelson, and much of Marlborough.
  • Ocean acidification—what is it?

    The on-going rise of carbon dioxide (CO2) in the atmosphere is not only changing our climate—it is also changing our oceans. 
  • NIWA's Hotspot Watch for 13 February 2019

    Hotspot
    Across the North Island, soil moisture levels continued to decrease nearly everywhere during the past week. Across the South Island, soil moisture levels decreased nearly everywhere during the past week with little rainfall in the north, south and east.
