Millions of Australians to face unusually warm spring as temperatures soar

Millions of Australians are set to sweat through an unusually warm start to spring this week, with parts of the east coast facing temperatures well above average.

Sydney is set to reach at least 20C every day for the next seven days for the first time in spring since 2013.

Temperatures in the city could reach 29C on Saturday, as warm and dry conditions settle in across the state.

A Bureau of Meteorology spokesman said the warmth was arriving “right on cue” for the start of spring.

“What’s notable is just how warm it will be this week,” the spokesman said.

“We are expecting the warmest first day of spring for Melbourne and Canberra in five years, and for Hobart, the warmest first day of spring in 13 years.”

Brisbane is also in for a sample of summer, with temperatures forecast to reach 31C by Thursday, then 32C on Friday, Saturday and Sunday.

But the warm and dry conditions come with a warning for NSW, with fire danger expected to increase as the state heads closer towards bushfire season.

Cooler conditions could return to Melbourne, Hobart and Adelaide, with a cold front forecast to move through on Tuesday.

On Tuesday, Sydney will have a top of 27C, with a clear, sunny sky and an overnight minimum of 16C.

Melbourne faces a top of 23C, with a shower or two expected and an overnight minimum of 12C.

Brisbane will be partly cloudy, reaching a maximum of 24C, with an overnight minimum of 13C.

Adelaide has showers developing, with a top of 22C and an overnight minimum of 11C.

Canberra has clear skies and sunshine, with a top of 20C and an overnight minimum of 7C.
