Low pressure covers central and northern parts of NZ today with higher humidity and downpours and hit and miss thunderstorms, with cooler airflows coming in to the south and east over the coming weekend. The cooler airflow is due to high pressure that will be situated south of New Zealand, dredging up subantarctic air in some regions.

But next week a low pressure zone leaving the tropics (around New Caledonia) may form into a tropical cyclone and drift southwards towards NZ. It’s likely the anticyclone south of NZ will affect the tracking of this low – and while the forecast one week from now is not yet locked in, the latest maps do suggest rain, wind and tropical humidity may affect the North Island.

We track the temperature changes, upcoming rainfall, and where high and low pressure is expected to be over the coming 8 days.
