Australia weather: Heatwave warning for NSW, WA, VIC, TAS, SA, Mid-week cold snap

There is a heatwave warning for five states on Boxing Day as a band of warmer conditions beats down on the nation from Western Australia to Tasmania.

The hotter conditions started to settle in on Christmas Day and will run to Wednesday in NSW, VIC, SA, TAS and WA.

Here’s what the weather is looking like in your state.


The western state could potentially nudge 45C on the mercury on Monday as a heatwave spread across most regions.

The red indicated on the map below indicates temperatures of 40C in widespread parts of the state.


The heatwave will start pushing across into South Australia on Monday, bringing a maximum temperature of 36 degrees in Adelaide, and 37 on Tuesday.

A severe heatwave warning is in place for the Riverland, Murraylands, West Coast, Lower Eyre Peninsula and North West Pastoral districts.

However, in keeping with the weather trend of late, the heat won’t stick around for long before a bitter cold snap grips the region from Tuesday night, plunging temperatures down by about 15 degrees.

“It’s a weak change and it’s bringing a bit of wet weather with it,” Sky News meteorologist Rob Sharpe said.

“That change coming through is bringing some showers, maybe some storms on the change itself and that will continue marching further northwards.”


Sydneysiders woke up to a thick blanket of fog on Monday morning ahead of the highly-anticipated Sydney to Hobart Yacht race which is welcoming back international competitors for the first time in three years.

A severe heatwave warning is in place for the south coast, Snowy Mountains, South West Slopes, Riverina and Lower Western Districts.

The heat will peak over most parts on Tuesday as maximum temperatures reach forty over southern inland parts of NSW.

Batemans Bay, Bega, Bombala, Balranald, Eden, Tumbarumba and Wentworth are all expected to be impacted.

The warmer weather is however expected to ease on Wednesday and Thursday following the passage of a cool change, according to the Bureau of Meteorology.

“Ushering in just that little bit of wet weather for Thursday, stormy for southern NSW and then into Friday the wet weather will start picking up with onshore winds on the east coast,” Mr Sharpe said.

The NSW north coast is looking to get particularly wet on Friday.

“Daily wet weather will then be a bit of a feature for eastern Australia,” Mr Sharpe said.

“Onward and into New Year’s Eve and New Year’s Day where there’s potential for a little bit of wet weather through the east.

“At the moment there’s a chance of a shower for Sydneysiders on NYE but that wet weather is looking to continue on into the start of next year.”


Residents of Victoria will also start feeling the heat from Boxing Day and into midweek.

The heat will peak on Tuesday with temperatures in the mid to high thirties, reaching forty in the northwest.

A cool change from the west will ease then ease heatwave conditions from Wednesday.

Locations likely to be impacted include Bendigo, Horsham, Mildura, Melton, Maryborough, Shepparton, Seymour, Swan Hill, Traralgon and Wangaratta.


The southernmost state will be the fifth state to experience the sweltering heatwave conditions in the coming days.

Starting on Sunday, the temperature began climbing and will likely stay high until Tuesday evening when a cold snap flicks the temperature down.


Ex-Tropical Cyclone Ellie is currently located around 50 kilometres south to southeast of Tennant Creek.

The system is expected to remain stationary over southwestern parts of the Barkly district on Monday and will continue to produce widespread and prolonged heavy rainfall and thunderstorm activity.

Flash flooding is likely over parts of the Barkly and Simpson districts with widespread six-hourly rainfall totals between 70 to 100mm.


A strong wind warning remains in place over QLD on Boxing Day.

The Townsville Coast, Mackay Coast, Capricornia Coast and Fraser Island Coast are all expected to be lashed by the strong winds until Tuesday.

A flood warning remains in place for the Diamantina River region where scattered rainfall fell.

In the 24-hours to 9am on Sunday totals of between 15-44 mm across northern parts of the basin were reported including a further 51mm recorded at Diamantina Lakes.


There is no heatwave warning for the nation’s capital but that doesn’t mean the temperatures won’t be climbing high.

From Monday to Wednesday, the temperature is expected to stay above 30C.

A cool change will bring wet weather from Thursday.

Staying safe in a heatwave

Severe heatwaves can be especially dangerous for older people, babies, children, pregnant and breastfeeding women, people with medical conditions and people who are unwell.

Here’s how to stay safe during the extreme weather.

  • Seek a place to keep cool, such as your home, a library, community centre or shopping centre.
  • Close your windows and draw blinds, curtains or awnings early in the day to keep the heat out of your home.
  • If available, use fans or airconditioners to keep cool.
