Sunday’s national forecast – Some thunder and heavy downpours today

A cold front is moving up NZ and the warmer than average sub-tropical airflow is about to ease for a time.

The mix of warm and cold airflows coupled with daytime heating is a good recipe for thunderstorms.

As you can see in the infographic below there is widespread risk today in the upper North Island for thunderstorm development. Please note, not everyone in the red shaded area will have a thunderstorm, but it’s the most likely area to see downpours developing.

Green indicates more heavy rain on the western side of both islands – the good news for the West Coast region is that tomorrow looks dry. 

For more details on today’s weather where you are please refer to your 10 day local forecast and hourly data to drill down further. Also, remember you can go to for even more weather data – this website has more NZ forecast weather data than any other site on earth.  (please note it does have a 10 second loading time – we are working on speeding that up by the end of summer).

I would say Wellington, Porirua, Hutt Valley had the best Thunderstorm night ever last night.
Torrential rain at times, great and bright lightening, and thunder to blow your socks and sockets off!
