Sydney, Melbourne, Brisbane, Perth weather: Temperatures set to break records in major city

Weather in Sydney, Melbourne, Brisbane, Perth: temperatures will break records in the big city

Perth is facing what could be the hottest September day in almost 150 years.

The weather forecast predicts temperatures in Perth could reach a high of 34 degrees Celsius on Wednesday, which is significantly higher than the city’s usual September average of 21.6 degrees Celsius.

If this forecast comes true, it could be the highest temperature ever recorded in Perth in September, surpassing the previous record of 34.2°C set in 2014.

Weather Zone meteorologist Aline Ribeiro suggests a low today could lead to this record temperature.

“There is a trough that brings in a hot air mass from the Pilbara region and slows the sea breeze (which would cool temperatures),” she told Daily Mail Australia.

‘There is a chance of very high temperatures in Perth today; it will be the hottest day of the next two weeks.

‘It’s certainly well above the average for the month; it will be very hot.’

However, the heat won’t last long.

“It will also be warm tomorrow before a cool change takes place on Friday,” Ms Ribeiro said.

This change is expected to drop temperatures back into the low 20s degrees Celsius.

But as the West Coast cools, the East Coast will warm up.

Showers around Sydney on Wednesday and Thursday are expected to clear on Friday as temperatures warm.

Maximum temperatures of 28 and 27 degrees Celsius are forecast for Friday and Saturday, with a maximum of 34 degrees on Sunday.

Melbourne will also see a warm weekend with highs rising from 17°C and 21°C on Wednesday and Thursday to 25°C and 28°C on Friday and Saturday.

High temperatures at the end of the week are expected to bring sunny conditions.

Wednesday looks set to be the hottest day for Brisbane this week with a high of 31 degrees Celsius.

These temperatures are expected to drop as rainy and cloudy conditions move over the city from Thursday.

Hobart is also forecast to see cloudy weather from Wednesday with high temperatures in the high to mid 20s Celsius.

Clouds will clear over Adelaide from Wednesday, for a mostly sunny Thursday and clear skies on Friday.

Temperatures in the South Australian capital will peak on Saturday with highs of 30 degrees Celsius.

The weather in Darwin is expected to be hot, dry and sunny, with clear skies and temperatures around 30 degrees Celsius forecast for next week.
