A springtime heatwave currently affecting large swathes of Australia's southeast, including Sydney, is predicted to intensify on Monday, according to the country's meteorological bureau. Temperatures are anticipated to soar to as much as 16 degrees Celsius (60 Fahrenheit) above the September average. The heatwave has been developing in the outback interior over the weekend and is expected to persist until Wednesday, impacting South Australia, Victoria, and New South Wales.
The Bureau of Meteorology has stated that it anticipates numerous early spring temperature records may be shattered in the coming days, characterizing the heat as "highly unusual for September." Relief from the scorching temperatures is not expected until Wednesday when a stronger cold front will pass through the southeastern states.
The Sydney marathon held on Sunday was adversely affected by the heat, resulting in 26 individuals being hospitalized and around 40 others treated for heat-related exhaustion by emergency services.
In Sydney's western areas, temperatures are projected to reach 36 degrees Celsius (96.8 F) on Monday before dropping to roughly 22 degrees Celsius (71 F) on Thursday, as per weather forecasts.
This heatwave has also raised the risk of wildfires, with several regions receiving 'high' fire danger ratings. Authorities have urged residents to be prepared for bushfires. While around 50 grass or bushfires are currently burning across New South Wales, they have all been brought under control.
Australia is preparing for a hotter southern hemisphere spring and summer this year as the likelihood of an El Niño event has increased. Weather forecasters suggest that El Niño could develop between September and November. El Niño can lead to extreme weather events in Australia, including wildfires, cyclones, and droughts. Authorities have already issued warnings about elevated bushfire risks for the upcoming summer season.
Last week, Sydney was enveloped in a thick smoke haze as firefighters conducted hazard-reduction burns in preparation for the impending bushfire season.
