Weather Australia: More heatwaves in Perth, Sydney, Brisbane, Adelaide and Canberra

The heatwave continues across parts of Australia, with several capital cities forecast to reach above 30C this week.

The Bureau of Meteorology forecasts Perth, Sydney, Canberra, Adelaide and Brisbane are likely to record higher temperatures as September comes to an end.

Bureau senior meteorologist Sarah Scully said 30-plus degree heat was forecast for northern parts of Australia from Tuesday afternoon before the hot temperatures extend down to northern parts of NSW in the coming days.

“This high pressure system in the (Great Australian) Bite starts to dominate, bringing clear skies and allowing those temperatures to start to build which is what we see particularly about the far western WA, pushing up into the mid-30s,” Ms Scully said.

“In fact, it’s from Wednesday onwards and towards the end of the week that record-breaking heat may occur across WA.

“As we move into Thursday, it’s pretty much rain-free right across the continent.

“Heat building is starting to be dragged southward and eastwards.”

Ms Scully said there were going to be temperatures well above average forecast across western and southern parts of the country over the coming days.

“The heat’s really starting to build across the far west, with maximum temperatures forecast between 8-16 degrees above average,” she said.

“The heats expected to continue to build across WA and across eastwards to southern Australia as we approach the end of the week.”

Ms Scully said records could be broken for both day and night-time temperatures for Perth, as the capital is set to reach a top of 34C on Wednesday.

“It really starts to build across southeast on Friday and into the weekend,” she said.

“Hot air isn’t really going to be flushed out until a cold front is pushed into WA on Sunday and Monday before moving eastwards mid next week.”

Brisbane is also set for a top of 31C on Wednesday.

Grand final weekend outlook

Residents in Victoria, NSW and Queensland are gearing up for a long weekend, with temperatures expected to remain high.

While Brisbane will just be shy of 30C across the long weekend, light winds are forecast to become north to northeasterly at 15 to 25km/h for both Sunday and Monday. morning.


Ms Scully said AFL fans could expect to experience a top of 28C on grand final day on Saturday, with warm and sunny conditions forecast.

“It’ll be really pleasant weather and warm weather for the long weekend,” she said.

“The UV index to expected be high, so it’s important to be sunsmart.

“Saturday night will remain relatively warm, still sitting around 20 degrees at midnight.”

For the footy fans, Ms Scully said Saturday’s AFL grand final between Collingwood and Brisbane Lions would be the fifth time in game history that temperatures would be above 25 degrees.

“The last time we saw heat like this was in 2015 for the Hawks vs Eagles and it got to 31.3 degrees,” she said.

Ms Scully said Saturday would be significantly warmer than the last time Brisbane met Collingwood back in 2002 and 2003 when temperatures reached 11.9C and 13.7C respectively.


Meanwhile, when the Brisbane Broncos take on the Penrith Panthers in the NRL grand final on Sunday, the bureau is forecasting players will be experiencing temperatures in the high 20s at kick-off.

“We’re forecasting a maximum 35 degrees at Olympic Park on Sunday, but the upside is the grand final is a night game,” Ms Scully said.

“It’ll be high 20s at the start of the game but then decrease throughout the game.

“However, the women’s finals game at 4pm will be at the peak heat which will be an added challenge.

“It’s important to stay hydrated.”

However, Ms Scully said a southerly change was going to push up the east coast of NSW early on Monday in time for the public holiday before a more significant cooler change next week.

“It’s going to be a really gusty cold front that could elevate fire dangers,” she said.

Hot September

As the week progresses, Adelaide will peak at 30C on Saturday and 33C on Sunday, according to the bureau.

The continued high temps come as Australia’s southeastern capital cities could have one of their hottest Septembers on record, according to Weatherzone.

However, NSW and eastern Victoria can expect “hit and miss showers” in the coming days.

Temperatures will be slightly lower in Melbourne, with the bureau forecasting a top of 18C on Tuesday and 17C for Wednesday.

There will be much cooler conditions in the far southeast near Tasmania, with max temperatures in the mid teens forecast for Tuesday and Wednesday.

The bureau also warns that coastal showers are continuing about the Queensland coast on Wednesday, while a strong marine wind warning remains in place for the Peninsula Coast.
