Those who didn't make the most of the scorching weekend will be sorry - that's it for the nice weather. This week will be dominated by muggy days.
Temperatures soared, clouds parted and the rain mostly held back, giving New Zealanders a much-deserved and long-awaited summer's weekend.
On Saturday the mercury soared, with highs of 29C recorded at Blenheim Airport and 27.8C at Gisborne Airport.
Yesterday was almost as sweltering, with temperatures that reached 27C at Kaikohe and 26C at Tauranga and Whangarei.
Auckland wasn't left out by the heat and hit a high of 24.4C yesterday, providing excellent weather for those who chose to venture to Devonport for the Food, Wine and Music Festival.
Other Aucklanders took advantage of the weather at the music festival Splore in Tapapakanga Regional Park in Manukau, while some made the most of the pop-up carless park created in lower Queen St yesterday.
But that's it for sunny days as hot and humid weather moves in.
A low coming from New South Wales in Australia will start to make its way over the South Island today before covering the North Island with heavy rain on Wednesday.
MetService forecaster Larissa Marintchenko said there was a chance of thunderstorms today.
"In Auckland, there'll be some isolated evening showers ... and rain will be developing on Tuesday."
Weather Watch chief analyst Philip Duncan said a large high lay out to the east of the country and a developing low lay to the west, which created a passage for a "very humid" northerly wind down the country.
"So that should help boost the temperatures right up, possibly over 30 degrees in Hawkes Bay," Mr Duncan said.
And even though most of the country should prepare for rain, particularly the North Island, Mr Duncan said it would be far from cold.
"It looks like it's going to be a hot, humid and muggy week, even if it is a bit wet."
Up until the weekend, most of the country would be covered by the slow-moving low, Mr Duncan said.
"I think it will clear up on Friday, maybe with a few showers hanging around, but I think it will clear up then," he said.
"But possibly another front could move past just after that low leaves."By Amelia Wade Email Amelia
