This winter will be warmer and drier than usual, the Bureau of Meteorology say.
The bureau has released its 2018 Winter Outlook, with warmer and drier than average conditions expected to follow one of Australia's warmest autumns on record and its second-warmest summer on record.
The outlook suggests winter rainfall is likely to be below average for New South Wales, South Australia, northern Victoria and western parts of Western Australia.
Daytime temperatures across much of the country are likely to be warmer than average, with the greatest chance (more than 80 per cent) in New South Wales, Victoria and Tasmania.
We’re also in for some comfortable nights, with overnight temperatures also expected to be above average across the country, except for parts of the tropical north.
Bureau climatologist Jonathan Pollock said there were many climate drivers influencing the weather:
"We're expecting warmer than normal temperatures in the Tasman Sea this winter and associated lower-than-normal air pressure. This would mean a weakening of westerly winds over southern Australia that normally draw cold fronts up from the Southern Ocean," Mr Pollock said.
"As a result of this, we're expecting to see below average winter rainfalls for western parts of Western Australia and for most of New South Wales extending across the border into southern Queensland and northern Victoria. For most other parts the chances of above or below average rainfall is roughly equal."
