“Palmerston North is forecast to be about 4C below average with a maximum of 20C, while, after a recent warm spell, Wellington is expecting only 17C, again, 4C below average.”
For the South Island, Christchurch is forecast to reach a high of 17C, below the normal high of 23C for this time of year. Gore and Invercargill are set to only reach 15C, which is a few degrees below average.
Meanwhile, Auckland is forecast to reach 22C, again a few degrees below normal.
But the good news for Auckland is the overnight minimum will be 13C. However, for Taupō and Wellington, the figure will be 6C and 10C respectively.
Bellam said much of the cold weather began sweeping across the South Island yesterday and will move off the North Island by the end of today.
He said it will still be cooler than average for a lot of places across the North Island, but by Wednesday, we could see temperatures in the high 20s as another northwesterly flow comes across.
He said once the cold weather moves on from Auckland today the region will see a fine working week.
“Sunshine with highs of 24C and minimums of 14 or 15C,” he said.
“We’re forecast to see a high of 31C for Ashburton and 29C for Timaru.”
