There is no escaping low to extreme heatwave conditions in three states today as scorching temperatures grip most of Australia.

The Bureau of Meteorology anticipates low to locally extreme conditions in New South Wales, Victoria, South Australia, the Northern Territory, Western Australia and Tasmania from today into next week.

Temperatures across the affected states will sit between the high 30s to low 40s with parts of Western Australia to reach the high 40s.

Victoria, South Australia and Tasmania are completely under a heatwave from today into Monday, with conditions ranging from low to extreme.

Melbourne is seeing a maximum of 31 degrees today which will heat up to 38 degrees from tomorrow into Monday.

It is looking to be the city’s hottest few days since 2014.

Adelaide’s maximum temperature is 36 degrees today, 38 tomorrow and 39 on Monday.

Hobart is avoiding the worst of the heat with a maximum of 26 degrees today and tomorrow before temperatures rise to 33 degrees on Monday.

In New South Wales, far northern, central, western and southern parts of the state are under a low to severe heatwave warning. The east coast is unaffected.

Sydney is slightly cooler with a maximum of 27 degrees today, 28 degrees tomorrow and 29 on Monday.

Most of Western Australia is under a low to extreme heatwave from today. Northern and southern parts, including Perth, are escaping the scorching temperatures.

Perth is feeling a maximum of 33 degrees today before it dips to 32 degrees tomorrow and back up again to 33 on Monday.

And in the top end, the Northern Territory is seeing a low to severe heatwave across most of the state from today.

Darwin will have a steady maximum temperature of 34 degrees from today into Monday.

Queensland is being spared from the heatwave but is, instead, facing intense flooding after copping more than 200mm of rainfall.
