Drought forecasting dashboard
NIWA and MPI are working together to develop a new drought forecasting tool. It uses innovative climate modelling, the latest in machine learning and other data-driven techniques to predict rainfall 35 days ahead. It will help farmers and growers better prepare for periods of dryness and drought.
Climate and weather
-
How do we determine past climate?
Information about past climate is obtained from piecing evidence together from various sources. -
HIRDSv4 Usage
NIWA's High Intensity Rainfall Design System (HIRDS) offers planners and engineers more certainty about the frequency of high-intensity rainfall events, enabling them to better design stormwater drainage, flood defence systems and other vital structures. -
Waikato
Waikato exhibits a range of climates due to the variety of landscapes in the region. -

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.
