Today is New Zealand’s coldest day of 2024 so far – and more frosty temperatures are due tonight and into the weekend.
Kiwis woke to frosts, snow, and bone-chilling winds this morning – but with it comes dry, fine and sunny conditions for most.
The National Institute of Water and Atmospheric Research (Niwa) said the country was in the middle of a “winter-like surge” with snow expected in the central North Island yesterday evening as polar air plunged temperatures to below zero.
MetService issued road snowfall warnings for four mountain passes in the South Island yesterday, with up to 5cm of snow expected to settle overnight last night.
Temperatures in Auckland, meanwhile, were forecast to drop to 6C overnight and to fall to 4C tonight. Throughout today, the daily high could hit 17C with fine conditions and cool southerly winds.
Frosts were also likely on Friday morning. MetService credited the cooler temperatures to a string of cold fronts sweeping the country with brisk, southerly winds.
MetService meteorologist John Law said it was possible Auckland could get frosts, and explained that clear night skies and cold winds created “perfect conditions” for cooler-than-average temperatures.

Coldest morning so far
Thursday morning was the coldest of 2024 so far, Niwa said.
Lake Tekapo dropped to -7.5C. Middlemarch fell to -6.5, Cass to -6.1C, Ranfurly to -5.6C and Lauder to -5.3C.
In the North Island, South Waiouru fell to -4.8C and the Desert Rd hit -4.4C.
Looking ahead to the weekend, the City of Sails could dip to 5C on Saturday night with a 7C overnight low forecast for Sunday. Saturday’s high was tipped at 15C while Sunday should reach 16C. Both days should see sunny skies and fresh southerlies.
Speaking of snow about the North Island, Law said: “If you’re in Hawke’s Bay tomorrow and you look out at the hills to the west of you, you may see a dusting of snow.”

The winter-like surge will reach Christchurch this evening, Wellington overnight & Auckland around midday Thursday.
It comes after Taumarunui started Wednesday at -4C. Taupō began the day at -2C. Further south, Christchurch woke to -3C, Timaru started at -2C and Queenstown saw -1C.
Niwa said this was a “fast start to the snowy season” and said Friday would be “a very cold day for the time of year”.

Some of the winds likely to buffet the country overnight tonight could reach 80km/h in exposed places around Westland, in the South Island. Gales were also possible around Wellington and Marlborough tomorrow morning.
The earliest road snowfall warning comes into place at 3pm Wednesday, for the Crown Range Rd. It should end at 6pm the same day.

Lewis Pass, State Highway 7, Arthur’s Pass, SH73, and Porters Pass were under road snowfall warnings from 7pm Wednesday at the earliest to 3am Thursday at the latest.
Flurries on the Crown Range Rd were recorded at 4pm Wednesday - promoting a warning from MetService to motorists to “drive safe and take care on the wet roads and poor visibility”.
MetService meteorologist Mmathapelo Makgabutlane said this May was a stark contrast with last year.
“Many may recall the tropical-feeling temperatures of May 2023, where places like Auckland and Hamilton experienced record-breaking warm nights. However, this year, expect an overnight drop to mid-single digits in Auckland City and early morning temperatures hovering near freezing in Hamilton,” Makgabutlane said.
