On Wednesday we have two high pressure systems centred either side of NZ, while a weak trough of low pressure sits above the country itself.

In the North Island, we will see a mix of sun and cloud, while isolated showers are possible late in the afternoon or evening for parts of the upper North Island.
Some of these may become heavy, with the possibility of thunderstorms – particularly for northern Taranaki and the central North Island.

Along the East Coast, skies are fairly cloudy with the odd shower about in the morning – then clearing by early afternoon, along with winds from the south.
Wellington sees morning cloud break into mostly sunny weather, while southeasterly winds die out later in the day.

In the South Island, morning cloud breaks away in the east to leave mostly sunny weather, while east to northeast breezes become brisk for some about the coast – especially Canterbury.
The West Coast sees sunny areas and some cloud through the day, with west to northwesterly winds.
