Sydney to soar to 40 on last day of summer

Sydney is set to soar to 40 on the last day of summer, with parts of the city’s west likely to reach 39°C or 40°C, while the city should reach 35°C before a late cool change arrives.

On Wednesday, temperatures topped 43°C in several spots in the Mallee region in Victoria’s northwest, while temps reached 44°C in at least two locations in far western New South Wales.

That heat has been tracking across southern Australia from west to east for several days, and it will finally reach the east coast on Thursday, with only Sydney’s coastal suburbs spared the worst of the heat.

Canberra is also in for a reasonably hot one with a top of 34°C expected, which will make Thursday one of the sweatiest days of the 2023/24 summer.

The national capital hasn’t had a particularly warm summer by its standards, with a hottest day to date of 34.8°C on December 9. Rain tends to keep a lid on extreme daytime temperatures, and as you can see on the graph below, Canberra has indeed had a wet summer.

As of Wednesday evening, the bushfire danger for Thursday is currently rated as high in about half of New South Wales, but it will pay to keep checking the latest info at the Rural Fire Service website.
