Southwest Pacific climate

NIWA undertakes climate services and research in and about the Southwest Pacific under the Climate Present and Past project.

Climate services

  • The Island Climate Update is a monthly bulletin which works with Pacific Island Meteorological Services and produces a three-month forecast for many island nations. 
  • The NIWA Tropical Cyclone Outlook is released before the start of the Southwest Pacific tropical cyclone season (around October) each year. This outlook provides an estimate of tropical cyclone numbers for the season ahead, taking into account antecedent climate conditions such as the El Niño-Southern Oscillation and past seasons with similar characteristics. The outlook is compiled with assistance from other New Zealand and regional partner organisations.
