Weather: 'Changeable' winter for New Zealand - NIWA

There's good news for anyone struggling with the recent plummeting temperatures.

Today marks the first day of winter, but NIWA says warmer temperatures are on the way.

Appearing on The AM Show on Friday, NIWA weather forecaster Chris Brandolino says it's going to be a "changeable" winter.

"Basically, [it's] like having nobody at the steering wheel," he says.

"It's a lot more variable, a lot more unpredictable so identifying what's going to drive our weather is unclear right now."

After a freezing and dry end to autumn, he says this month could switch to warm and wet.

"June is not going to start off that way," he told host Duncan Garner.

"In June, it looks to be one of the break-out parts of winter. We think if there's going to be a warm part of winter it'll likely be in the month of June, especially for the North Island.

"And if there's going to be a lot of rainfall for the northern and eastern parts of the country, and the eastern part of the South Island, it'll likely be in the month of June."

And the rain is likely to kick in within days for the North Island, ruining plans for Queen's Birthday weekend.

"It's going to be wet, and even a bit windy - especially Saturday night and Sunday morning," he says.
