A taste of winter is coming this weekend and for some in the deep south they’ve already experienced hail and sleet in the past day or two.
An incoming southerly change on Sunday will dramatically hack daytime highs across southern and eastern areas of both islands – while also dropping temperatures as far north as Northland.
“This is coming from a sizeable storm in the Southern Ocean, which will remain south of the country, but the squash zone between this powerful low in the south and the strong high in the north will push gales and rain into southern parts of both islands this weekend” says WeatherWatch.co.nz head weather analyst Philip Duncan.
The low will churn south of New Zealand well until next week, with the coldest of the weather moving northwards across Sunday and Monday.
“Invercargill will go from highs around 12 or 13 to highs of 7 and 8 this coming Sunday and Monday. The wind chill factor will certainly feel below zero in exposed places” says Mr Duncan.
Dunedin will drop from around 14 degrees today, Friday, to a high of only 9 degrees on Monday.
Further north and Christchurch heads up to 19 degrees for Friday, then 13 for Sunday and only 11 on Monday with frosts possible overnight Monday and into Tuesday.
Wellington will slide from highs around 16 degrees to a high of 11 on Monday with southerlies.
WeatherWatch.co.nz says northern centres, such as Hamilton, Auckland, Whangarei and Tauranga, are unlikely to be as dramatically affected by the colder air change like the centres further south. Highs will slide a degree or two by Monday and Tuesday but the bulk of the cold snap will be south of Wellington.
Winds, however, may be a little chilly for Monday across northern areas, but a high over the Tasman is expected to move in for Tuesday for the North Island settling things down and bringing a risk of frost and perhaps a little fog for Tuesday and Wednesday – while southerners see warmer westerlies returning, becoming strong again by Wednesday.

I agree with the above comment… Palmerston North, Main Central Region hardly ever gets a mention, but while its is understandable you cant include every city, Palerston North should be MADE mentioned as it is the Secondary Airport as with Ohakea for Planes that are diverted away from Wellington, are sent to, (and (rarely) sometimes international flights) when the Capital is shut down through fog, and strong winds. This should be mentioned at least through the winter months.

Oh boo hoo about palmy. Its most times more wind there than Wellington. Have something better to say about this great site, that offers all you need for weather watchers. Keep up the great work guys.

I was just wondering about what the temperatures might be on monday night and tuesday morning in Auckland. This is when the cold fron reaches auckland right? Metservice is predicting temperatures as low as 4 degrees in auckland, and at freezing point in Hamilton. But here, this is not the case (7 degrees for auckland at night ). I really trust you guys, but why is there such a large difference between the two predicted temperatures?

I’ve noticed when you do your weather outlooks Taranaki does not get a mention. As a fan of your site I would like to see a few heads up of what weather we might get. Cheers

We mention Taranaki often in our morning and evening forecasts, sometimes we include Taranaki in the Western North Island forecast, sometimes we’ll have Taranaki by itself depending what the weather is like.
Will put a note through so that Taranaki gets more of a mention in general stories however. 🙂
