THERE’S been a break from the scorching hot weather. But summer is on the way back with heatwaves forecast across the country’s south.

AFTER a refreshing cool spell, the heat is making a return this week with a host of capitals likely to see temperatures in the high 30s and Adelaide topping out at a possible 40C by the weekend.

Parts of Sydney and Brisbane could also hit the 40C mark, Canberra is likely to get to at least 35C with Melbourne not far off as heatwave conditions making a reappearance.

“There’s been a bit of a nice reprieve from that heat but it’s coming back again particularly for the south of the country,” Sky News Weather meteorologist Rob Sharpe told news.com.au.

“In Adelaide, the heatwave is going to persist across much of the week. It won’t be quite as intense as the previous heatwave that crossed southeast Australia, but we’ll still see some pretty hot temperatures moving through,” he said.

“In Adelaide, the long-term average for February is 28.5C but on Sunday they got to 34C and that will rise this week to the point they will have six days in a row above average.”

Mr Sharpe said the South Australian capital was often in the heatwave firing line due to its position closer to the red centre and because it was further north than a number of other capitals. Heat lingers for longer in SA, he said.

But South Australia isn’t the only place due a dose of sun. The mercury will be rising in just about every eastern capital this week. A low- to severe-intensity heatwave will creep across SA, Victoria and much of central and southern NSW and the ACT.

Melbourne will peak at 34C on Wednesday while Canberra will hit 35C on Saturday. Sydney CBD will reach a summery 29C on Saturday but Penrith in the city’s west will climb as high as 39C. Brisbane will be a toasty 37C on Sunday but in neighbouring Ipswich 40C will be in order.

Regional areas of Victoria and NSW will be hotter still with Mildura and Albury likely to reach and possibly streak past 40C towards the end of the week.

“The reason it will get so hot is a high pressure system is setting up in the Tasman Sea off the NSW coast. Because the winds travel anticlockwise around high pressure systems, we have north-westerly winds drawing heat from the north of the country down into the south and that’s where it will sit for a number of days,” Mr Sharpe said.

However, a cool change is due and will spread gradually from south to east, sweeping through Tasmania and Victoria first.

“In Melbourne, the heat will spike around Wednesday or Thursday but then they will have a proper cool change during Saturday. But that will push the heat into the east of the country,” he said.

In Sydney, it will be Sunday when the heat begins to dissipate. Adelaide’s big drop will come at the end of the week with 39C on Friday followed by 29C on Saturday.

Further north in Queensland, rain has been the big feature with 30mm in the last few days in Brisbane. In the tropics it has been torrential with 148mm falling in Innisfail in Far North Queensland in the 24 hours to 9am on Monday.
