One week out, forecasts suggest Christmas Day across Australia will be typically hot, humid and thundery in the north, windy in the south, wet in the southeast and dry on the west coast.

At this stage, our computer models tell us that a front should be crossing southern Australia, bringing a cooler, gusty change with a low pressure trough causing some rain over southeastern Australia and in the north of the country.

Possible estimated extremes one week out are –

Hottest – 24-degree minimum and 43-degree maximum at Roebourne in Western Australia’s Pilbara

Coldest – 4-degree minimum and 11-degree maximum at Mt Read in Tasmania

Wettest – 29mm at Camooweal in Queensland’s northwest

Cloudiest – 3 hours of sunshine at Mt Isa in Queensland’s northwest

Sunniest – 14 hours of sunshine at Nuriootpa in South Australia’s Barossa Valley

Windiest – 80km/h at Mt Hotham in Victoria’s North East

Calmest – 20km/h at Quirindi in New South Wales’ North West Slopes and Plains 

As we get closer to the day, models will change and accuracy will improve, giving us different places and amounts, so stay tuned for updates.
