Temperatures are climbing in Sydney ahead of a scorching week with heatwave conditions lingering on the NSW coast.
Hot air will move across the country causing an autumnal heat spike, pushing Sydney’s CBD over 31C for the first time this year with a forecast 36C on Monday.
“Summer heat not seen since September 2021 will arrive on Monday across NSW where millions will feel the warmest in over two summers,” Sky News meteorologist Alison Osborne said.
Grassfire activity has been increasing over the weekend across the state with an Extreme Fire Danger warning issued for the Greater Hunter, Central Ranges and Lower Central West Plains regions.

The heatwave will also impact parts of Queensland and Western Australia, while parts of Tasmania could see snow.
Heavy rains in the Top End continue to bring flooding risks and have blocked off a key transport route to Western Australia.
Bureau of Meteorology (BOM) senior meteorologist Sarah Scully said hot conditions on the eastern coast are due to shifting hot northerly winds moving ahead of a cold front.
“For much of NSW on Monday through to Wednesday it will be hot and windy, elevating fire dangers particularly about the NSW Ranges and Western Slopes,” she said.

“We’re expecting low intensity heatwave conditions for parts of eastern NSW … while southeastern Australia will have a series of cold fronts with temperatures dropping well below average.
“There’s even a chance of snow about elevated parts of Tasmania on Wednesday.”
Heavy rains will continue to batter the Top End, courtesy of a monsoon trough dipping down over Cape York Peninsula over Queensland.
“That’s drawing in moisture over Northern Australia at the moment, bringing increased storm activity,” Ms Scully said.

“A number of flood warnings and watches have been issued across northern parts of the country.
“There’s a number of impacts on the community, last week very heavy rainfalls across the Top End resulted in a number of communities being evacuated – it’s actually eased, however that large body of water that created those flooding conditions last week is moving downstream.
“This has caused flooding over the Victoria River crossing, the main route for transport between the NT and WA, and it’s expected to remain impassable until Thursday.”
Western Australia has had some heatwave relief, with some very isolated patches of low intensity heatwave conditions to occur over the next week.
