Temperatures to soar again
Christchurch's cold weather today is a blip on the radar, with temperatures to soar again this week.
For the past few days Christchurch has reached upwards of 30 degrees Celsius, with a high of 32C yesterday.
However, the temperature is sitting around 13C today.
MetService forecaster John Law said the weather should brighten this afternoon, but cloud would continue until tomorrow.
He said the fluctuating temperatures were because of a change of airflow.
Northerly winds came from the tropics and southerlies were pushed up from Antarctica.
''A change of air mass can give you a change of temperature.''
He forecast a northwesterly change on Thursday, with a high of 29C.
A southerly change on Friday would bring some rain and cooler temperatures of about 20C, with a high of 29C.
Cantabrians could also expect hot temperatures during the weekend, he said.
At least 32 flights in and out of Wellington were cancelled because of fog today.
All but two of the flights were Air New Zealand services. The other two were Jetstar flights.
The arriving flights affected were from Christchurch, Dunedin, Blenheim, Taupo, Westport, Nelson, Napier, Hamilton and Gisborne.
Flights departing Wellington to the same centres have also been cancelled.
MetService forecaster Ian Gall said dense cloud that blanketed Wellington's hill suburbs this morning was expected to stick around for much of today.
With temperatures getting down to only 17C last night and expected to reach 21C today, the warm weather was combining with moist air to create the cloud and fog.
There was no significant wind on the way to ''flush'' it away, meaning fog and cloud were expected to stick around until tomorrow morning.
However, there may be a break in the clouds for a short time this afternoon.
The warm air was coming from north of New Zealand.
Among disrupted travellers is a Christchurch superhero's sidekick, Quake Kid.
Flat Man and Quake Kid, students who wear costumes and wish to remain anonymous, are due to be honoured tonight in the final Christchurch earthquake awards for their work delivering food parcels to struggling families, quake-hit residents and students.
The pair also regularly visit primary schools to share their motto, "Be a bruv, share the luv".
Christchurch company Stadium Cars has organised a chartered plane to get Quake Kid to Picton, where he will pick up a rental car and drive to Christchurch.
''Hopefully he'll make an unforgettable entry to the awards,'' Flat Man said.
