  • ‘Weather detectives’ saving historical records

    Media release
    More than 50 “weather detectives” from 20 countries will be in Auckland next week to share their experiences saving snippets of meteorological history that will ultimately help scientists better understand the processes of climate variability and change.
  • NIWA's Hotspot Watch for 30 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.
