Four-day heatwave will be 'shock to the system'

Parts of Australia are set to endure a four-day heatwave with temperatures set to reach the high 30s and early 40s over the weekend.

Authorities are on high alert as the Australia Day long weekend approaches with people's health at risk in the sweltering temperatures.

NSW Health Acting Director of Environmental Health Aditya Vyas warned there was risk of heat-related illness in coming days and urged people to take extra care.


"Hot weather puts a lot of strain on the body, including dehydration, and can make underlying health conditions worse," Dr Vyas said.

"Protect yourself during the heatwave by postponing or rescheduling your outdoor activities.

From tomorrow, a mass of hot air from central Australia will sweep down between now and Australia Day, increasing temperatures for large parts of eastern Australia.

The Bureau of Meteorology's (BOM) Gabrielle Woodhouse said the heat will be "a shock to the system" and will definitely be noticed after a cooler than usual start to summer.

"We haven't really been experiencing this kind of heat, compared to say last summer," Ms Woodhouse said.

"It's going to be a bit of a shock to the system for many people, so it is quite significant because we haven't been seeing these temperatures recently."

Ms Woodhouse said the risk of fires would be elevated and temperatures would be "eight to 16 degrees above average in some areas".

The intensity and persistence of the impending hot weather will see it classified as a severe heatwave for parts of WA, South Australia, NSW, Victoria, Tasmania and the ACT.

Some places will even endure an extreme heatwave, which is the highest category used by the Bureau of Meteorology.

Extreme heatwaves are considered rare in Australia and anyone living in impacted areas are urged to take precautions to protect themselves to avoid heatstroke.

So how hot and sweaty are things about to get in your part of the country?

South Australia

Adelaide hasn't yet had a 40C day this year but that is likely to change this weekend, with tops forecast of 39C on Saturday and 41C on Sunday.

Temperatures will be several degrees warmer in the north of the state, with areas like Oodnadatta – which recorded Australia's highest ever temperature of 50.7C in January 1960 – heading for at least five straight days of maximums in the low to mid-forties.


Melbourne has had only two days above 30C so far this January, making it a relatively cool start to the year in comparison with 2020.

It will miss the worst of this heatwave, with a top of 38C predicted on Sunday but no other days of very hot weather.

Areas in the north of the state will be much hotter for much longer. Mildura in the state's northwest will likely see three consecutive days of temps of 40C or higher, peaking at 45C on Sunday.



There's nothing too drastic in the forecast for Hobart, with several days in the mid-twenties predicted. But the north and northeast of Tasmania could see much hotter conditions, especially around Monday, with temperatures tipped to reach the low to mid-thirties.


Canberra is heading for tops of 37C, 38C and 39C on Saturday, Sunday and Monday respectively.

That's still a far cry from January 2020, when Canberra recorded its hottest ever temperature of 44C. But it will be easily the warmest spell to date in a month when the hottest temp has been just 34.4C .

New South Wales

Sydney's west will bear the brunt of the upcoming heatwave with temperatures expected to be significantly hotter inland than on the coast.

The city and eastern parts of the city should reach tops of 30C, 32C and 33C on Saturday, Sunday and Monday respectively.

In the city's west, those tops will be much closer to 40C, and could even reach 41C in Penrith and other outer western suburbs.


Further west in NSW, a prolonged spell of at least four days of very hot weather can be expected across a wide area of the state, with maximums around or above 40C in many towns.

The far south coast of NSW will also cop some extreme heat, with Bega likely to see 42C on Monday.

Western Australia

This heatwave will largely bypass Perth after a particularly hot January.

The WA capital's hottest weather of the week will be on Thursday and Friday, with tops of 34C and 36C respectively.

Perth's average top temp so far has been 33.9C – nearly three degrees above the long-term average.

The heatwave will, however, touch the state's southeast, with Eucla tipped to reach 42C on Saturday.
