Temperatures are set to hit as high as 40C in South Australia, Victoria and NSW on Tuesday as a heatwave continues to sweep south-east Australia before a chilly shift sets in.
Adelaide is expected to hit 40C, with some South African cities – Oak Valley, Wudinna and Murray Bridge – expecting an even hotter 43C, according to the Bureau of Meteorology.
A maximum temperature of 37C is expected in Melbourne, while many other areas in the state will reach 40C. Ouyen, Birchip and Warracknabeal in Victoria’s Mallee and Wimmera face 41C.
The Riverina and Lower Western region of New South Wales is set to be hot, with Hay, Wentworth and Lake Mungo forecast to hit 40C. The state capital, Sydney, will see a cooler 28C.
There is also a heatwave in Tasmania, with Hobart set to hit 30C on Tuesday. Launceston to the north will experience a hotter 34°C. Ouse in the state’s central highlands is expected to hit 36C.
Parts of Western Australia are also hit by a heatwave. Marble Bar – known as Australia’s hottest city – is expected to hit 44C.
A heat wave is categorized as warmer than average temperatures for more than three consecutive days.
Heatwave warnings are currently in place for much of south-east Australia, with hot northerly winds pushing Tuesday’s maximum temperatures to between 6C and 16C above average, BOM said.

Cool change is coming for the Southeast
A chilly change is on the horizon in the south east, but Sky Weather meteorologist Rob Sharpe said many parts of Victoria and Tasmania were still in for a potentially record-breaking hot night.
“Maybe Melbourne or Launceston could come close to their all-time record for hot December nights,” he said.
Melbourne is not expected to drop below 26C overnight, while Hobart’s minimum temperature is forecast at 22C and Adelaide at 17C.
The chilly change is expected to hit Adelaide overnight, Melbourne around noon on Wednesday and Hobart in the afternoon.
There will be gusty conditions in Melbourne and Hobart ahead of the chilly change and a severe weather warning for damaging winds has been issued for the central and eastern mountain ranges in Victoria.
Wet weather will accompany the cool change, with mostly showers and isolated thunderstorms possible.
High temperatures will drop 10C to 15C on Thursday and Friday if the change catches on, to average or below average, BOM said.
“By Thursday afternoon it will also be slightly cooler along the NSW coast…however humidity levels on the NSW coast will still remain fairly high despite the drop in temperature,” Mr Sharpe said.
