Introduction to the Heatwave
The current heatwave affecting South Australia and Victoria is expected to bring extreme fire conditions to the region. By midday on Wednesday, temperatures had already reached 37C in Melbourne and 41C in Adelaide, with severe to extreme intensity heatwaves stretching from the north-west to the south-east of the country. The Bureau of Meteorology has warned that many areas can expect temperatures in the low to mid-40s, with some places potentially reaching as high as 47C.
Temperature Expectations
Adelaide and Melbourne are anticipating "sweltering conditions", peaking at 42C on Wednesday, according to senior meteorologist Miriam Bradbury. Temperatures are expected to reach as high as 44C in Elizabeth, in Adelaide’s north, and 46C in Murray Bridge, in SA’s Murraylands region. The hottest part of the day is expected to be early afternoon, around 2pm or 3pm, with temperatures remaining close to their maximum into the evening. Bradbury has warned that "these are really dangerous conditions" and that "it’s not just a normal burst of summer heat".
Fire Danger Ratings
The added threat of isolated, dry thunderstorms has raised concerns for emergency services, with Commander Ann Buesnel of SA’s Country Fire Service stating that the landscape is "really dry" and that "everything is essentially ready to burn". Authorities have advised people to enact their bushfire plan, stay informed, and avoid taking any risks. The BoM has warned that the heatwave is the most significant since the 2019-20 black summer, with extreme fire danger forecast for western and central areas of Victoria on Wednesday.
Precautions and Warnings
People are being advised to take precautions to reduce the risk of heat stress, including low-intensity exercise and staying hydrated. The Royal Australian College of GPs has warned against complacency in high temperatures, advising people to "stay hydrated and stay indoors if you can". Dr Michael Wright, president of the college, has urged people to "check in on friends and family members who are more vulnerable to the impact of heatwaves, including older people". Authorities have also warned that the hot and dry conditions will make it difficult for firefighters to suppress a fire should one start.
Climate Crisis and Extreme Weather Events
The climate crisis has increased the frequency and severity of extreme weather events, including heatwaves and bushfires. Australia experienced its fourth-warmest year on record in 2025, with average temperatures up 1.23C nationally, according to the BoM. The current heatwave is a reminder of the importance of taking precautions and being prepared for extreme weather events. As the climate crisis continues to worsen, it is essential that people take steps to protect themselves and their communities from the impacts of heatwaves and other extreme weather events.
Conclusion and Future Outlook
The current heatwave affecting South Australia and Victoria is a significant event that requires precautions and attention. With temperatures expected to remain high over the coming days, it is essential that people take steps to protect themselves and their communities. The climate crisis has increased the frequency and severity of extreme weather events, and it is crucial that we take action to reduce our impact on the environment and prepare for the challenges that lie ahead. By staying informed, taking precautions, and being prepared, we can reduce the risks associated with heatwaves and other extreme weather events.
