High winds, temperatures reaching 31C in parts of South Island

MetService Christchurch weather: February 24th.

Temperatures across most of the South Island have skyrocketed today, with Christchurch taking the top spot as the warmest.

According to Metservice, the city reached temperatures of 30.9C at about 1.30pm on Tuesday.

That compares to the coldest place, Nugget Point in Clutha, with 17.5C.

MetService meteorologist Alwyn Bakker said a foehn wind is responsible for the warmer weather.

"That is when you get a strong northwest flow over the Southern Alps, bringing a traditional northeasterly wind which will be very warm."

As well as warm temperatures, high winds are also forecast for most of the South Island, meaning fire crews are on high alert.

A strong-wind watch is in place for Fiordland, Southland and the Queenstown-Lakes district from 9am on Tuesday to 7am on Wednesday.

"North to northwest winds may approach severe gales in exposed places," Bakker said.

There is also a warning in place for the Canterbury High Country, starting from 6pm tonight until 1pm on Wednesday.

A post on the Canterbury FENZ Facebook page said firefighters were battling a large fire in Rangiora this morning ,where temperatures had already reached 20C by 7am.

"Winds are expected to reach gale force, so if you have had a permitted fire in the last couple of weeks (other than crop stubble) we ask that you check the piles and ensure they are extinguished. As the wind is likely to stir something up.

"Reminder that permitted or approved fires are not to be lit in high winds," the post said.
