Wetness is favoured for the northern North Island, with dryness a possibility for the western part of the North Island as well as western South Island, according to the latest Seasonal Climate Outlook for May to July 2025, issued by NIWA.
Seasonal air temperatures are expected to be above average across all New Zealand regions, says NIWA meteorologist Principal Scientist – Forecasting & Media, Chris Brandolino.
“”Low pressure systems forming north of the country are expected to affect New Zealand and may lead to heightened risks for heavy rainfall events. In the absence of strong large-scale climate drivers, local and regional influences – inherently less predictable – are likely to dominate New Zealand’s climate over the forecast period.”
Chris Brandolino breaks down what New Zealanders can expect over the next three months. Will it be a warmer than average start to winter? Who is going to see above normal rain? And what does it mean for skiers, farmers, and hydro catchments?
