Good Old BOM... you have done it again...
A cold snap left millions of people shivering across parts of Australia over the King's Birthday long weekend.
Temperatures plunged in NSW, Victoria, South Australia and Tasmania before it was Queensland's turn to experience a blast of frigid weather.
Residents were told to expect minimum temperatures to drop five to 10 degrees below the seasonal average.
But overall, Australians have been told to expect warmer than usual days this winter.
So why have we had such a cold start to the season?
What is the official outlook for winter
Large parts of the country, including Sydney, Perth and south-west Western Australia, and Melbourne and much of Victoria, have more than a 50 per cent chance of recording unusually high maximum temperatures from June to August.
Even more of the country has a high chance of unusually warm minimum temperatures throughout winter.
"Yes, we had a very cold spell last weekend.
"The bureau's forecasting of that cold event was very accurate.
"But they can't get the same accuracy in forecasting seasonal outlooks, because there's not the same dominance of circulation.
"In practice, forecasting weather beyond about a one week timescale is quite uncertain and quite unreliable because of the chaotic variations that we see with forecasting."
