We’re in for a wetter than average spring and cooler than usual temperatures in some parts of Australia, the Bureau of Meteorology announced on Thursday.
The bureau released its 2020 Spring Outlook and revealed the chance of above average rainfall for the country’s eastern and southern regions “is above 80 per cent”.
Daytime temperatures are likely to be average to below average throughout southern Australia, and warmer than average in the north.
The BoM last week moved its La Niña likelihood from watch to alert with the climate driver set to occur in spring.
La Niña, typically brings increased rainfall, cooler temperatures in southern parts of Australia and warmer overnight temperatures in the north.
Overnight temperatures are likely to be above average for the entire country, with the only exception being southwest Western Australia.
BoM’s manager of climate operations, Dr Andrew Watkins, said warmer temperatures in tropical Pacific and Indian oceans were behind the changes.
Dr Watkins added La Niña “typically brings cooler and cloudier days, more tropical cyclones, and an earlier onset of the first rains of the northern wet season”.
"At this time of year, we start to see some of our main climate drivers locking in, which gives more certainty about what our weather patterns will be like in the coming months,” he said.
"We’re starting to see that in the Pacific with a La Niña beginning to take shape, and we are also seeing some changes in the Indian Ocean, which may also boost the chance of rain during spring."
NSW and ACT spring weather
NSW and areas across the east coast will warm up for spring with above average maximum temperatures this weekend due to a warm mass of air moving from the west coast. Sunday will be the warmest day of the weekend with 25 forecast for Sydney.
NSW and the ACT have a greater than 80 per cent chance of exceeding median rainfall over the spring – particularly in central and western parts of the state.
The mid to mid north coast has a slightly lower chance of exceeding median rainfall though.
Higher than average temperatures are predicted.
Victoria spring weather
Victoria is predicted to have warmer than average temperatures especially at the start of spring until mid-September.
Central and northern Victoria have a high chance of exceeding median rainfall.
Western Australia spring weather
Western Australia doesn’t have the same expectations of exceeding rain with only the far southeast of the state expected to experience higher than average rainfall.
Average to drier than average conditions are likely across the remainder of the state.
There is also a high chance of exceeding median maximum temperatures in the northeast, with predicted higher than average temperatures across the state.
South Australia spring weather
It is very likely South Australia will be wetter than average across spring.
Average to cooler than average days and warmer nights are expected due to increased cloud cover.
Tasmania spring weather
Northern and western parts of Tasmania are a high chance of receiving above average rainfall.
All of Tasmania is also set for above average temperatures.
Queensland spring weather
The north half of Queensland should receive above average temperatures.
South and southeast parts of the state have a high chance of exceeding average rainfall.
Northern Territory spring weather
The southeast of the Northern Territory has a high chance of above average rainfall but won’t have a high chance of exceeding median maximum temperatures.
