We have a high to the east of New Zealand in the Pacific, and a low in the Tasman Sea – while in-between, a northeasterly airflow covers the country.

Meanwhile a front moves in from the west, pushing into the west of the South Island in the afternoon, then onto the west of the North Island in the evening.

The South Island is cloudy all over, as rain spreads onto most of the east coast in the morning, then spreading north into Marlborough through the afternoon.
The West Coast of the South Island sees rain from morning – becoming heavy in the afternoon about the Glaciers northwards – then easing later in the evening.

For the North Island we can expect high cloud for most, thickening for all regions during the day.
Showers fall in Northland from morning, spreading into Auckland around midday, and then further south in the west during the afternoon and into evening.
There may be a heavy fall or two in the west during the evening and late afternoon, from Northland down through to Kapiti, Taranaki and Northland.
Some rain then spreads onto the East Coast of the North Island later in the evening from the west.
