Temperatures will plummet this week as a series of icy cold fronts travel across southeastern Australia, marking the unofficial start of the ski season. 

Freezing cold air will sweep through New South Wales, Victoria, and Tasmania with the high country expected to receive some light snow. 

According to Weatherzone, the mid-week chill heralds the unofficial start of the ski season, with several days of fresh snowfall on the cards.

‘Wednesday night and Thursday morning will be particularly cold, with minimum temperatures forecast to reach -5 to -7°C in the Vic and NSW Alps,’ it said. 

The real chill is expected to hit over the weekend, when two cold fronts are forecast to impact southeastern Australia.

This back-to-back system is expected to deliver a steady stream of cold air and snowfall, with snow likely each day from Saturday through to at least Tuesday.

The timing couldn’t be better for ski resorts, with the King’s Birthday long weekend approaching.

‘Tuesday’s front won’t deliver a lot of natural snow,’ Weatherzone said.

‘But it will cause temperatures to drop and allow ski resorts to make plenty of artificial snow in the lead-up to the weekend.’

The June long weekend typically signals the start of the ski season for most of the main ski resorts. 

However, early June can be unreliable when it comes to natural snow and in years past, there hasn’t been enough coverage to open slopes this early.

But this year looks more promising.

‘Fortunately, Mother Nature will be kindly serving up several bursts of cold weather over the coming week, including a good bout of fresh natural snow over the long weekend and early next week,’ Weatherzone said. 

On the west coast, Perth is set to receive its heaviest rainfall this year as a slow-moving low pressure system brings up to 85mm of rain on Tuesday and Wednesday.

Western Australia’s south-western regions will cop a soaking after a relatively dry start to 2025 with below-average rainfall in the capital. 

The extreme conditions in the first week of winter comes after Australia experienced its fourth warmest autumn on record.
