Severe heat will grip Sydney’s western suburbs from Sunday as a low-intensity heat wave sweeps across south-east Australia

Suburbs including Penrith, Glenmore Park, Mt Druitt and Granville could see temperatures reach 35 degrees between Sunday and Tuesday.

Overnight lows are expected to remain in the high teens, making nights hot and uncomfortable.

Sky News meteorologist Rob Sharp said warm air was gradually moving across South Australia and Victoria and was likely to rise into New South Wales from Sunday.

“Over the next few days, this heat wave will gradually spread further east, passing through Victoria and into south-east New South Wales,” he explained.

“Even Western Sydney is seeing a low-intensity heat wave from Sunday to Tuesday, in the mid-30s each day for western parts of Sydney as the heat wave looks set to grip the region.”

South Australia found itself in the firing line of hot weather on Thursday, with Adelaide recording its hottest November night in seven years.

“South Australia is the target at the moment, that’s where we’ve seen the hottest weather, but it will gradually move east over the next few days,” Sharp said.

“Temperatures rose to 36 degrees in Adelaide yesterday… overnight it was South Australia that was the target of this heat wave, Adelaide’s warmest November night since 2017, staying above 26 degrees all night.

“The heat continues across South Australia today, with winds picking up slightly and the heat flowing into western NSW and Victoria.

“With these gusty winds in SA, we are actually seeing extreme fire weather on the west coast and Eyre Peninsula, as well as high fire danger in the east of the state and western parts of Victoria.”

A heat warning remains in place this weekend for large areas of Victoria and parts of south-east NSW.

Bureau of Meteorology heat wave maps show conditions could become severe in areas near Mallacoota, the East Gippsland region of Victoria and further north towards Eden in NSW.

“Extreme heat can be dangerous for many people, especially older adults, infants, children, pregnant and breastfeeding women, people with medical conditions, and people who are unwell,” the bureau said in its warning.

“Look for a place where you can stay cool, such as your home, library, community center or shopping center. Close windows and draw blinds, curtains or awnings at the start of the day to keep heat out of your home. If possible, use fans or air conditioners to keep things cool.”

The hot weather in Victoria and southern New South Wales is expected to subside from Sunday.
