Kiwis can look forward to scorching hot temperatures next week but before you get used to it WeatherWatch warns a cold snap is coming the week after.
According to the forecaster, temperatures are about to lift across the country, with next week set to be much warmer than it usually is in mid-April.
WeatherWatch said the reason for this is because of a large high-pressure zone that will be parked east of New Zealand encouraging a sub-tropical airflow from around Tonga to drift down across the country for several days.
"It's not too often in mid-April you're seeing daytime highs in the 20s and/or overnight lows in double digits for basically a week, especially in the lower South Island," WeatherWatch.co.nz head forecaster Philip Duncan said.
Duncan said Kiwis right around New Zealand shouldn't experience any frosts next week because of the warm airflows.
But before you get used to the summer temperatures again, Duncan warns that will all change the following week.
"As we said in our ClimateWatch update for April, the forecast this month was that of chaos," Duncan said.
"Big highs and big lows helping to produce all sorts of weather from all directions. While next week looks warmer than average by day and night across almost all of New Zealand thanks to the sub-tropical airflows, the following week (the last one of April) looks the opposite with westerlies and sou'westers dominating from out of the Southern Ocean."
Duncan said this will bring snow back to the southern mountains and overnight lows back to where they should be for this time of year.
"In fact, the lower and western South Island looks to be colder than average in April's last week," Duncan said.
"Classic autumn ups and downs!"
It comes after New Zealand saw five cyclones since Sunday - the first struck East Auckland, then Tasman District, then New Plymouth and Paraparaumu and lastly the Bay of Plenty.
Thursday weather "unstable" - MetService
Metservice warns conditions over the North Island on Thursday are "unstable", with daytime cloud buildups producing scattered heavy showers or thunderstorms.
"There is a moderate risk of isolated thunderstorms over Northland this morning, then this afternoon and evening from Waikato and the Coromandel Peninsula to Northland, and also about the inland ranges of Gisborne and Hawke's Bay," MetService warned.
"These thunderstorms will produce localised heavy rain and small hail. There is also a low risk that some of the thunderstorms from about Hamilton northwards could be severe this afternoon and evening, with localised downpours of 25-40 mm/h."
Metservice added there is a low risk of thunderstorms for many other North Island areas.
