InfoGraphic: The Main Weather News Highlights across NZ: Tue, Wed, Thu

A high covers most of New Zealand today, breezy easterlies for the far north. A ridge weakens on Wednesday then a front slowly moves southwards over the upper North Island later in the day, a cold front moves onto the lower South Island later in the evening / overnight. This cold front combines with a warm front coming out of a low in the Tasman Sea on Thursday over central South Island regions and may deliver some warm advection snow to inland areas. Meanwhile an occluded front continues to move southwards over the North Island during the day.


Blue – A frosty start about much of the inner South Island, no major frosts just standard in the range of 0 to -2 degrees celsius.

Purple – Easterly winds becoming breezy about eastern Northland from afternoon.

Some fog also possible about inland / eastern parts of the North Island this morning then breaking away.


Blue – From afternoon heavy showers may start to affect Northland then slowly slipping southwards through to Coromandel overnight.

Overnight there may be some heavy rain about South Westland for a time.

White – A cold front pushes onto the lower South Island later in the evening then moves into Otago overnight, this front carries with it fairly cold air so some snow may develop to 300m for a time however it is looking to be fairly brief at this stage then easing or perhaps clearing around dawn on Thursday as this frontal feature moves northwards.

Purple – Easterly winds about Northland and Auckland are fairly gusty, moving a little further southwards in the evening.

A pre frontal northwest airflow becomes gusty about coastal parts of the lower South Island from morning then easing later in the afternoon.
