Wednesday’s National Forecast – Rinse and repeat inland…

Another Groundhog Day for New Zealand with a repeat of weather conditions: Coastal clouds and warmer than average airflows leading to inland deluges later in the day with the risk of localised flash flooding, hail and thunder.

Generally speaking high pressure dominates New Zealand but a humid nor’east flow is helping spark inland downpours.

Northland, Auckland, Waikato & Bay Of Plenty
Cloudy and sunny spells. Light winds or light east to north east breezes. Dry or mostly dry but risk of downpours in Waikato later in the day with possible thunderstorms.
Highs: 21-25


Western North Island (including Central North Island)
Dry for most coastal areas with more sunny spells, inland large downpours developing with heavy rain through the Central Plateau area and some of the southern and eastern ranges.  Thunder, hail and flash flooding possible.
Highs: 21-25


Eastern North Island
Cloudy areas, especially inland where rain may develop around the ranges during the afternoon with heavy downpours and isolated thunderstorms. Rain may spread east to the coast in places.
Highs: 21-24


A mix of sun and cloud with light winds mainly from the north.
Highs: 22-25


Marlborough & Nelson
A fairly hot day, especially inland. A mix of sun and cloud with afternoon cloud build ups producing big downpours and possible thunderstorms on the ranges. Northerly quarter winds.
Highs: 24-27


Winds mainly off the sea with cloudy areas continuing, building in the afternoon with isolated downpours developing along the ranges with possible isolated thunderstorms later in the day, otherwise the region looks fairly dry and quite cloudy.
