It’s the day to break out the barbecue and enjoy the company of friends in the outdoors – but will the weather wreck Australia Day for 2022 in your city?

If you’re living in Adelaide and Melbourne, then the answer to that question could be yes.

WeatherZone meteorologist Jess Miskelly told Yahoo News Australia a slow moving pressure trough will hang over South Australia well into Thursday.

“Adelaide will be quite warm and humid [on Australia Day] we’re also expecting severe thunderstorms over South Australia while Melbourne will reach a top of 34 and will also be quite humid and muggy,” she said.

The Bureau of Meteorology is forecasting Melbourne to reach a top of 34 and low of 21 with up to 2mm of rain so there is a chance you might need to break out the umbrella.

Adelaide will be slightly cooler with temperatures ranging from 21 to 31 and a chance of an afternoon or evening thunderstorm.

The humidity is also likely to continue in Sydney too. On Monday, many areas around Sydney had between 60-80 per cent humidity at about midday.

Ms Miskelly said Australia Day in Sydney is also going to be “muggy”. It won’t quite reach 30 though with a top of 28 forecast and partly cloudy conditions, according to the BoM.

Canberra is forecast for a max of 29 and low of 15 with overcast conditions and the potential for late afternoon showers.

Brisbane can expect similar conditions with a top of 29 and mostly cloudy. There is also the chance for morning and afternoon showers with up to 5mm.

Ms Miskelly put the humidity along the east coast and south towards SA and Victoria down to a pressure system off the coast of Tasmania.

“This summer’s weather patterns have been unusually stagnant and the pressure system off Tasmania has seen humidity moving inland,” she said.

“That pattern normally moves away.”

Residents of Tasmania will still be experiencing a low intensity heatwave.

Ms Miskelly said those living on the island’s coastal areas will be largely unaffected though.

Hobart will see a top of 25 with a chance of showers of up to 6mm.

Perth residents sweltered through their sixth consecutive day above 40 degrees on Sunday, so it will come as a relief that Australia Day will finally see a drop in temperature.

Wednesday will still be a scorcher though with a top of 33 and low of 17.

Light rainfall could potentially dampen Darwin’s Australia Day ceremonies with up to 8mm and potential thunderstorms forecast.

Ms Miskelly said a monsoon trough is currently active bringing wet conditions throughout the week. It will also be “ridiculously humid”, she said.

Australia Day in Darwin is forecast for a top of 33 and low of 25.
