Wetter, colder winter on the way, says weather bureau

A state-by-state guide to what winter will look like as temperatures prepare to plummet across the country.

Much of Australia is in for a wetter and colder winter this year, which could prove welcome news for the country's drought-ravaged farmers after a horror summer.

But night time temperatures are likely to be warmer than average, the weather bureau says.

The Bureau of Meteorology has released its 2020 winter outlook, predicting increased rainfall in the next three months.

It follows a record-breaking start to May, with some states experiencing freezing temperatures as a cold snap swept across much of the east coast.

Wetter than average winter

"Most areas of mainland Australia are showing a better than 70 per cent chance of having a wetter than average winter," the Bureau's manager of long-range forecasting, Dr Andrew Watkins, said.

"The only exceptions are the coastal fringes of NSW and eastern Victoria, parts of Tasmania and areas of southwest WA where the outlook isn't pushing towards wetter or drier than average conditions."

Northern Australia is not expected to be affected, Dr Watkins said, due to winter being the dry season.

The "better than average rainfall" was due to warmer ocean temperatures off north-west Western Australia, as well as warm ocean temperatures in the western Pacific.

"When warm sea surface temperatures occur closer to Australia, weather patterns shift towards us too, favouring more cloud and rainfall across the country," Dr Watkins said.

Cooler days, warmer nights

Following a record-breaking summer – where Penrith in Sydney's west became "the hottest place on earth" with temperatures peaking at 47.3 degrees on January 7 – a cooler winter is likely to be a welcome change for many.

Daytime temperatures during winter are likely to be cooler than average for much of the southern half of the country.

But it'll be warmer than average along the eastern seaboard and most of northern Australia.

In good news for those who struggle with the cold nights, overnight temperatures are likely to be warmer than average across the entire country.

"When we look at the expected temperatures, they really fall in line with the expected rainfall conditions," Dr Watkins said.

"Areas with a higher chance of above average rainfall are also looking at increased chances of cooler than average days because they are more likely to have cloud cover and more evaporative cooling in the coming months.

"Conversely, it means our nights are more likely to be warmer than average, because that cloud cover will prevent heat from escaping during the evenings."

The forecast follows a warmer than average autumn across much of northern and western Australia, interspersed with periods of very cold weather.

The country as a whole is currently tracking drier than average, the bureau said.
