    Map E North

    Eastern North Island
    Gisborne, Napier, Masterton
    Sheltered by high country to the west, this zone enjoys a dry, sunny climate. Warm dry settled weather predominates in summer. Frosts may occur in winter. Typical summer daytime maximum air temperatures range from 20°C to 28°C, occasionally rising above 30°C. High temperatures are frequent in summer, which may be accompanied by strong dry foehn winds from the northwest. Extreme temperatures as high as 39°C have been recorded. Winter is mild in the north of this region and cooler in the south.

    How do we determine past climate?

    Information about past climate is obtained from piecing evidence together from various sources.
  • Northland

    Northland, with its northern location, low elevation and close proximity to the sea is characterised by a mild, humid, and rather windy climate.
  • New Zealand Drought Monitor

    Service
    The New Zealand Drought Monitor is a system for keeping track of drought conditions across New Zealand based on a standardised climate index.
  • Understanding and predicting floods and their impacts

    Feature story
    Floods are not unusual in New Zealand, but those that hit us early this winter broke records. Why did they occur? Should we expect more? Can we predict future floods?

    Map North

    Northern New Zealand
    Kaitaia, Whangarei, Auckland, Tauranga
    This is a sub-tropical climate zone, with warm humid summers and mild winters. Typical summer daytime maximum air temperatures range from 22°C to 26°C, but seldom exceed 30°C. Winter daytime maximum air temperatures range from 12°C to 17°C. Annual sunshine hours average about 2000 in many areas. Tauranga is much sunnier with at least 2200 hours. SW winds prevail for much of the year. Sea breezes often occur on warm summer days. Winter usually has more rain and is the most unsettled time of year.
  • Farming and the primary sector

    Farmers are making business decisions everyday which are influenced by environmental factors. We can help farmers to improve decision-making, mitigate farm environment risk, and to become more productive, efficient, competitive and sustainable.
