Thunderstorms and Heatwaves Collide Across Australia This Weekend
16 Oct
Summary
- Severe storms forecast to hit parts of NSW on Friday
- Heatwave conditions expected to scorch southern Australia
- Temperatures in South Australia could reach up to 45°C
As of October 16th, 2025, Australia is bracing for a weekend of extreme weather, with severe storms forecast for parts of New South Wales and a scorching heatwave expected to scorch the southern regions of the country.
According to the weather forecasts, a low-pressure system is set to sweep across NSW on Friday, bringing with it the potential for damaging 90km/h winds, large hail, and heavy rain. The thunderstorm activity is expected to develop over central and northeastern parts of the state, including Sydney, before spreading into the northeast in the afternoon and evening.
While the eastern states brace for intense storms, the southern regions of Australia are gearing up for a heatwave that could see temperatures soar to 45°C in South Australia on Sunday. This mass of hot air is currently expanding over Western Australia and is expected to spread across the south of the country over the weekend.
Forecasters warn that these high temperatures could potentially break previous records for this time of year, with the highest-recorded temperature in South Australia during October being 45.4°C in 1995. The last time anywhere in Australia reached 45°C this early in October was in 2014 and 2004.
