On Tuesday we have two anticyclones, one centred either side of New Zealand – connected by a ridge of high pressure running over the centre of the country.

South Island

The South Island will pretty much all have mostly sunny weather, although there could be some morning cloud about – though this will clear, with light winds in the morning and then afternoon sea breezes.

North Island

For most of the North Island, sunny areas will mingle with cloud on the East Coast with easterly winds – the cloud may be thicker in the morning.
From the Waikato northwards, all the way through to Northland, there may be isolated showers in the afternoon and into the evening, with the risk of an isolated heavy fall.

Winds for most of the North Island will be light in the morning, then turning afternoon sea breezes – just like the South Island.
Northland is the one exception, with easterlies for much of the day.
