A front slowly moves northwards over the upper South Island today reaching the lower North Island late afternoon / evening. Gusty northwesterlies precede the front, changing southwest behind. This front weakens over the North Island on Tuesday, a ridge brings mainly settled weather further south. A northerly airflow increases on Wednesday.

Blue – Some rain about Tasman, the Marlborough Sounds and perhaps Nelson may be heavy at times, easing from afternoon. Late afternoon rain moves into Kapiti with heavy falls possible, moving a little further north in the evening.

Purple – Northwesterlies through the Cook Strait area are brisk / strong then easing this evening.

Tuesday

Blue – Rain about the upper North Island may be heavy early morning then easing away.

A frosty start for much of the inner South Island, generally no major frosts with 0 to -2 degrees most common. -4 isn’t out of the question in some isolated inland spots.

As a northerly quarter airflow increases over New Zealand during the day northwesterly winds becoming gusty through Cook Strait and northeasterlies strong about coastal Fiordland from afternoon.

– Please note, the idea behind this update is to focus on the main weather highlights, which is why not all regions are mentioned.
