Australia is getting ready for a very hot week next week, with temperatures soaring to 45°C in four states as an upper-level ridge over the country is causing the heat wave. This situation will produce a large heat trough that will first cover WA with extremely hot weather and then gradually spread to the east.
How Will The Heat Spread Across Australia?
The temperature will go up quickly in WA this weekend, and the whole state will be experiencing low to mid-forties by Monday. The following week, the heat wave will shift to SA and central Australia, reaching Vic and NSW by midweek. The inland parts will be the hottest, but the major cities will also be feeling the heat.

What Are The Expected Temperature Peaks?
The computer simulations have indicated that WA, SA, Vic, and NSW could face temperatures of 45 to 46°C, and even in some regions, they might go up to 48°C. The city of Adelaide is expected to have a maximum temperature of 39 to 41°C next Wednesday and Friday, while Melbourne is likely to experience 30 to 39°C from Wednesday to Friday. The northwestern Victorian town of Mildura may reach 45°C on Thursday, with slightly higher temperatures just inside the SA border.
Heatwave Conditions To Extend Across Multiple States
The extremely slow progression of this heat wave will lead to the very hot weather conditions all over WA, SA, Vic, and Tasm, which will be a concerning issue in all the Australian states and territories. The severity might lead to an increase in the fire danger level, which will be particularly high in southern Australia on Friday, and hence, outdoor activities will be unsafe.

How Can Residents Stay Safe During Extreme Heat?
The Australian Red Cross recommends remaining indoors, refraining from heavy activities, consuming large amounts of fluids, and utilising either shading or air conditioning as ways to keep homes cool. Also, cool baths, opening windows when it is cooler outside, and scheduling activities for either early or late can reduce the risks associated with heat exposure.
Extreme Heat Forecast for Australia Next Week Signals Fire Risks
The high temperatures could lead to very fire-prone and dangerous situations, especially in the interior regions of Australia. It is advised by the authorities to keep an eye on the daily forecasts and to take emergency advice. The residents inhabiting the areas that are likely to experience a heatwave are advised to be ready with their heatwave emergency plans and also to lessen fire risks both indoors and outdoors.

Preparing For Record-Breaking Temperatures
After the fierce temperatures projected may vary, but the 45°C heatwave anticipated over four states of Australia denotes the need for taking precautions without any delay. The careful planning of outdoor activities, consuming a lot of water, and keeping up with the official updates are all very important for safety. The coming very hot weather will be one of the main early-year meteorological events in Australia.
Preparing For Extreme Heat And Fire Risks
Residents across the affected states are urged to take urgent precautions as the heatwave approaches, including staying hydrated, limiting outdoor activity, and using air conditioning or shaded areas. Authorities recommend monitoring local forecasts closely, planning travel carefully, and keeping emergency supplies ready. With fire danger ratings expected to rise, reducing flammable materials around homes and following official fire warnings can help prevent disasters. The coming week marks one of the most intense early-year heat events in Australia, demanding vigilance and preparedness from all communities.
