Warmer than average days are expected through March for much of the country.
Kiwis can stock up on Frujus and sunscreen, with forecasters predicting sunnier and warmer-than-usual days for most of the country this summer.
Temperatures are expected to be warmer than an average summer over the next few months and into March, according to models from the National Water and Atmospheric Research Institute (NIWA).
Driven by warm northeast winds and above average ocean temperatures, warm days are expected through March, especially for the North Island.
But parts of the east coast of both islands could experience a few cooler days thanks to more land winds, Niwa meteorologist Chris Brandolino said.
* Summer temperatures above normal, soil humidity lower for some regions
* Lifeguard urges people to swim in patrolled areas after man dies at Mount Maunganui
* Floods, heat, humidity and a gloomy capital: what about the weather in early summer in New Zealand?
The past few weeks have been unusually sunny – Auckland had its hottest day of summer on Tuesday, reaching 29 degrees Celsius – and Brandolino said it was a sign of what was to come.
Next week is expected to be “very hot” across the country – especially in the North Island, he said.
Ocean temperatures were somewhere between 1.6 ° C and 2.5 ° C warmer than they usually are and La Niña also brought a warm northeast wind blowing from the tropics.
MetService sent out heat alerts in early January as temperatures reached the late 1920s and early 1930s.
“As an island nation we are closely related to the way our sea temperatures move, our air temperatures are generally closely aligned with that,” Brandolino said.
“So you throw northeast winds because of La Niña, warmer than usual ocean temperatures and in the background you have climate change that’s part of the equation. “
But while hot days would be good for vacationers and Kiwis who were locked up for much of the end of last year, drought could prove to be a problem as well.
Brandolino said rain levels are not expected to fall too much below normal, but will likely arrive in large gusts, so the arid soil could provide ideal conditions for flooding.
Still, hot days are a sign of things to come, as climate data from Niwa has shown New Zealand has experienced four to five times more temperature extremes over the past decade than one might expect. wait in a climate without long-term warming.
Through an analysis of more than 70 years of climate data, Niwa scientists found that extreme events were increasing at a rate much faster than the average average temperature.
“As the averages increase, so do the extremes,” Brandolino said.
“People have experienced and will continue to experience climate change through extremes. “
