Australia’s summer bares teeth as the heat is unfurled from the west
As always, the heat came from the west and spread across the vast interior of Western Australia before hitting the continent.
Mayor Linley Shine said the streets were empty when it hit Port Augusta in South Australia’s outback on Wednesday. “We’re very used to extreme weather in Port Augusta, so people here generally know how to deal with it.”
One of the town’s residents was more colorful. “It feels like we are microdosing against heatstroke,” Tata Jane said in a comment on social media after the temperature reached a maximum of 46.3 degrees in the state.
This was too much for the local Mr. Whippy Ice Cream van. Minibus owners announced in their post on Facebook that they were taking a break due to high temperatures.
Large parts of Australia are experiencing the worst heatwave in six years; In five states and territories, the mercury rises above 40 degrees.

“This appears to be the most significant multi-day heatwave event across inland southeastern Australia since 2019-2020,” said Angus Hines, senior meteorologist at the Bureau of Meteorology.
The highest temperature ever recorded was recorded at Onslow on the Pilbara coast, where temperatures reached 49 degrees.
Hines said the heatwave affecting south-eastern Australia began as temperatures rose inland and northern WA. “This is often referred to as Australia’s heat engine,” he said. “We see this very hot air accumulate quite routinely in the northwest of the country during our summer months.”
“And then when the weather changes, the wind can drag that heat and carry it to other areas,” he said. “In this case, the hot air moves in very quickly…so it drifts across the desert and stays extremely hot.”
“Then the wind that draws it in also increases the fire potential,” Hines said.
Midweek temperatures reached 40 degrees in central Melbourne, while the maximum temperature in Geelong rose to 43.3 degrees. Mallee and Wimmera were cooked at 44.7 degrees.
While there was relief on Thursday as temperatures dropped into the low 30s in southeastern Australia, authorities were bracing for new dangerously high levels on Friday.
Hines said “very serious fire conditions” were expected in Australia’s south-east, warning of a dangerous combination of intense heat and strong winds. Dry storms expected in parts of the Southeast will further increase the risk of wildfire.
“It looks like we’re going to see some areas of catastrophic fire danger right now,” he said. “Tomorrow is a bad day in many ways.”
An extreme fire danger rating was set to cover the rest of Victoria and a complete statewide fire ban was declared. Emergency warnings have been issued for fires currently burning across the state.
The worst is still to come for NSW, with temperatures rising in the state’s west and south, with Sydney set to peak at the weekend.
It could be 33 degrees in Sydney’s CBD and 42 degrees in Penrith on Friday. Saturday will be the toughest day for Sydney; Temperatures are expected to be 42 degrees in the city and 43 degrees in the western parts.
Rural Fire Brigade to guess Extreme fire danger forecast for the Greater Sydney Region as well as the Southern Ranges, ACT, Monaro Alps region and Southern Slopes on Saturday.
Sydney’s heatwave is expected to finally ease on Sunday; A high of 26 degrees and up to 3 millimeters of rain are expected for both the city and the west of the city.
Climate change is affecting how heat waves occur around the world. 2025 to work The study, published in the journal Nature and analyzing 213 heat waves that occurred globally between 2000 and 2023, found that “climate change is making all events more intense and probable.”
The study found that a quarter of heatwaves analyzed were “almost impossible without climate change.”
Copernicus, the European Union’s climate monitor, announced late last year that 2025 would be the second hottest year on record, along with 2023.
According to the organization’s statement, the hottest year ever was 2024; “it was the first year in which the average temperature was clearly 1.5 degrees Celsius above the pre-industrial level.” Annual Climate Summary.
Climate scientist Professor Lesley Hughes said the world was warming in line with predictions.
“As a scientist, I am not surprised by the current temperature,” he said. “It’s hard to be hopeful when we see that we’re not moving fast enough… We must continue strong action on pollution as the next few years are critical to avoiding much worse heatwaves.”
