A cool change has delivered relief to thousands of Australians in two states, but the summer-like heatwave rippling across the nation’s south-east persists in NSW.
Swathes of NSW, Victoria and South Australia have endured periods of 12C above the March average during a sweltering weekend.
Melbourne raced to 35C — and a touch more in its western suburbs — on Saturday, while Adelaide peaked just short of 40C.
It has been hotter still inland, with Mildura in Victoria’s northwest hitting 41C and South Australia’s Renmark and Port Augusta 42 degrees on Saturday. The hottest place in the nation was at Ceduna, which reached 44.1C.
A change has brought cool comfort to South Australia and Victoria’s north-west, but Sydney is still bracing for a Sunday maximum of 38C after enduring an uncomfortable overnight minimum of 26C.
“The heat will really be across NSW on Sunday,” Bureau of Meteorology senior forecaster Jonathan How said.
“Most areas will see temperatures of six to12 degrees above average and that means temperatures will soar into the mid-to-high 30s inland, even pushing 40 degrees through western parts of the state.”
Along the coast, residents can expect high 30s, including for the Illawarra and Hunter Valley. In Sydney, gusty winds will accompany the swelter.
When is the cool change expected?
“The change is currently tracking across south-western parts of Victoria and is due in Melbourne and Hobart later this morning and then we will see it push through the rest of Victoria,” Howe said early on Sunday.
“For NSW, we will see the cool change push up the south coast and it’s due in Sydney late tonight, around midnight, with a southerly buster to bring some gusty winds as well.”
Showers, cold winds and thunderstorms are likely to follow.
High and possibly damaging winds are likely in alpine areas of Victoria and NSW into Monday, as is snow across Tasmania’s highlands.
Meanwhile, a grassfire propelled by heatwave conditions destroyed one home and damaged another at Montrose on Melbourne’s outskirts on Saturday night.
South Australian firefighters are also battling blazes near Katarapko Island, north-east of Adelaide, and in the state’s lower south-east near Lucindale.
