It will be mostly fine today ahead of strong winds and rain about the lower South Island overnight.
Settled and relaxed weather was set to continue through the week, MetService meteorologist Angus Hines said.
The upper North Island will have some morning cloud about Auckland and Gisborne before becoming fine in the afternoon.
The lower North Island would see some cloudy periods about the west coast from New Plymouth to Wellington with some showers expected.
It was much the same for the South Island with morning cloud expected and showers about Greymouth and Westport on the West Coast.
"Overall a fine day for most places.
"However, for the far south things do take a turn for the worse towards the evening, with strengthening westerly winds.
"We are also expecting some rain to push to the south and southwest of the country. Invercargill could see a wet end to the day."
A front was expected to approach the lower South Island from the southwest on Tuesday evening, westerly gales will affect the far south on Tuesday night and Wednesday morning.
A strong wind watch was in place for Clutha and Southland near the coast, including Stewart Island with gales approaching severe strength in exposed areas.
A ridge of high pressure is forecast to dominate much of the country during Wednesday and Thursday.
However, a front was expected to move over the far south of the country from the southwest early on Wednesday, that would be preceded by strong westerly winds.
There was low confidence, a 20 per cent chance, of warning amounts of rain around southern Fiordland, coastal Southland and Clutha on Wednesday.

A change toward well above average temps is on the cards, just in time for the long weekend! It may even feel a bit summer-like out there 🌴 pic.twitter.com/jEOW5kLq8k
Southwesterly winds could approach gale force in coastal Southland, coastal Otago and south of Dunedin on Wednesday morning.
Another weak front was forecast to affect the south of the South Island early Thursday, bringing rain.
