Victorians are set to swelter through a scorcher of a week, with the mercury forecast to rise to 46 degrees in some parts of the state.
And it’s expected to be as warm as 23 degrees during the night.
Tuesday – the second day of the Australian Open – will be one of the hottest days in Melbourne this week, with temperatures tipped to hit 35 degrees.
A total fire ban has been declared across Victoria for Tuesday, meaning fires cannot be lit in open air, anywhere in the state over the entire day.
Towns along the Murray River will face the most intense weather on Wednesday: Mildura, Echuca, Swan Hill and Wodonga are all expected to reach 46 degrees.
Light winds and sea breezes will likely spare Melburnians from the most extreme heat.
“In some respects we’re saved by the sea breeze [in Melbourne], with much higher temperatures further inland,” said Bureau of Meteorology senior forecaster Richard Carlyon.
“It will be warm, but Melbourne is missing the extreme heat due to the lack of northerly winds.”
Yet the mercury soared to 40.5 degrees in Viewbank, in Melbourne’s north-east, on Monday afternoon.
As temperatures climbed, emergency services were forced to issue another warning about the dangers of locking children in cars during summer.
A baby boy was locked in a car in Derrimut, in the city’s west, about 11.15am. Paramedics were called to help rescue the boy.
Victorians will get little relief until the weekend, with a series of warm nights throughout the week.
Melbourne’s minimum temperature is forecast to be 19 degrees on Tuesday, 21 on Wednesday, 20 on Thursday and 23 on Friday.
“We will have to get used to warm nights,” Mr Carlyon said.
