Australia is on track for one of the warmest winters ever: What’s causing it?

  • 2025 could be hottest year on record

Australia is on track for one of the warmest winters on record, as much of the country enjoys mild temperatures in the lead-up to the cold season. 

‘The seasonal transition toward winter has been remarkably mild across Australia,’ Sky News Australia Meteorologist Rob Sharpe said on Thursday.

‘There’s barely been a whiff of winter looming with only a few cool spells. Much of the country has seen summer-like or March-like nights in the past few weeks.’

Mr Sharpe said the two most recent winters in Australia had been the warmest on record, and the current season, which officially starts on June 1, looked similar.

A string of towns in Victoria and Tasmania, including Hobart, recorded their warmest ever May mornings on Monday and Tuesday.  

The cause was warmer ocean temperatures, which heavily influence the weather across days, months and seasons. March and April have seen some of the warmest ocean temperatures on record – behind only 2016 – while the previous five months were the warmest. 

‘All climate forecasts suggest a warmer than usual winter for the country,’ Mr Sharpe said.

‘It is quite likely this winter will be within the top six warmest on record – with a decent chance of challenging the two most recent.

‘Of course, there will be cold outbreaks just like in the last two winters, but they will almost certainly be less frequent than in the Australia of 70 years ago.’

It comes as 2025 could turn out to be the hottest year the country has ever seen with minimum temperatures for the first four months the warmest recorded.

Taken together, the combination of highs and lows is a little behind the record year of 2019.

But Mr Sharpe believes once May’s data is included, the year to date should become the hottest on record. 

The latest forecast from the Bureau of Metereology showed sunny weather in store for Melbourne, Perth and Adelaide weekend, with showers for Sydney. Below is the outlook for major cities over the next few days.
