  • NIWA's Hotspot Watch for 4 April 2019

    Hotspot
    An increase in soil moisture in many areas across the North Island, including Northland, Auckland, Waikato, eastern Bay of Plenty, Gisborne, and Taranaki. No significant change in the South Island. Outlook is for low to moderate rainfall, countrywide.
  • 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.
  • NIWA's Hotspot Watch for 20 March 2019

    Hotspot
    Hotspots are now located across the majority 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 now located in a portion of interior Marlborough, eastern Banks Peninsula, and the lower Southland coast.

  • NIWA's Hotspot Watch for 6 March 2019

    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.

  • 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.
  • 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.
  • NIWA's Hotspot Watch for 7 February 2019

    Hotspot
    Across the North Island, soil moisture levels decreased nearly everywhere during the past week. In the South Island, soil moisture levels decreased during the past week with meagre rainfall in the north and east.
  • NIWA's Hotspot Watch for 31 January 2019

    Hotspot
    Areas deemed hotspots have expanded significantly during the past week in the North Island, while in the South Island the previous hotspot encompassing Nelson and nearby portions of Tasman has continued to strengthen during the past week.
  • NIWA's Hotspot Watch for 23 January 2019

    Hotspot
    The previous hotspot in the Far North dissipated around the Aupouri Peninsula in the past week, but has spread south into northern Whangarei and Kaipara districts. The current hotspot in Tasman could strengthen in the next week, while central Canterbury may see a new hotspot form in the coming week.
  • NIWA's Hotspot Watch for 16 January 2019

    Hotspot
    The previous hotspot in the Far North has expanded in size during the past week, now encompassing much of the eastern Far North and the Aupouri Peninsula. A hotspot remains in place across Nelson and nearby portions of Tasman, but no other South Island hotspots are in effect at this time.
