High temperatures ahead this week
Christchurch is set for another couple of scorching days this week, but weather forecasters do not expect it to get quite as hot as it was on Tuesday.
The city sizzled under temperatures of about 33 degrees Celsius on Tuesday - the hottest day of the summer so far.
Blue Skies weather forecaster Tony Trewinnard said the heat was forecast to return tomorrow and Saturday, but not quite to the same level.
"We've got a low pressure system coming in from the Tasman Sea tomorrow that's going to drive the wind just a little bit more north-west than it has been . . . so we can expect some pretty high temperatures."
He expected a high of 30C tomorrow - lower than Tuesday because there would be more cloud and not as much sunshine.
"The difference between a high 20s day and a 30s day is sunshine. We will have quite a bit of high cloud so I wouldn't expect we'd get quite as hot."
However, the high cloud would probably clear on Saturday, which could put the temperature into the low 30s.
Trewinnard said 30-degree days had been "noticeably absent" in Christchurch this summer, but the city was "catching up a little" this week.
"There's no indication in the longer range data that that's a permanent change though," he said.
Metservice has been slightly more conservative with its forecasting this week, suggesting a likely high of 29C tomorrow and 27C on Saturday.
The hot weather is not expected to last though, with the high dropping to 19C on Sunday. Light winds and a chance of early and late showers have also been forecast for the end of the weekend.
