North Island


Northern NZ feels like the tropics + Cyclone Gita's possible future track (+10 maps)

The upper North Island is officially wetter than it should be for this time of the year (no kidding!) as humidity up to 100% along with heavy rain and isolated thunderstorms continues today and to a lesser degree on Wednesday.

Water vapour satellite maps show the exceptionally damp airflow connecting to the tropics and even around the area Cyclone Gita is in.

How much rain will you get this weekend? The latest rainfall estimates (+4 Maps)

The low this weekend north west of New Zealand is large but weak and it's tapping into moisture rich sub-tropical air. A blocking high pressure system to the east of the country is slowing down these rain bands.

Here's the latest outlook by our meteorologists at the Weather Company showing forecast rainfall accumulations in 12 hour segments for New Zealand.


The fine line between heavy rain and drizzle/dry this weekend

Filed in:

UPDATED -- "Why is the chance of rain shifting around this weekend?" is a question we've been asked a bit this week The answer is this: The low is quite weak, the rain bands are patchy and the heaviest falls are in a narrow area meaning a slight shift west or east could make the difference between heavy prolonged rain or just patchy stuff with long dry spells.


Weather Video: Sub-tropical humidity, rain and drizzle moving in

A large but fairly weak sub-tropical low will drag down more humid northerlies this weekend and areas of rain - some slow moving heavy falls are in the mix but so too are drizzle patches and dry spells.

The low isn’t very strong so the rain bands will weaken in some areas due to the mountains and ranges getting in the way.


InfoGraphic: The Big Picture for Saturday

An east to northeasterly airflow continues over the country on Saturday.

Most regions in the North Island see rain on Saturday, heavy falls still possible for many but there will also be many areas of lighter rain or perhaps even some dry spells.
