Experts have predicted Australia will be forced to endure one of its wettest summers ever – with infamous weather pattern La Nina to blame.
Last summer was the country’s wettest and coldest in several years – and 2021 sounds will be no better.
Dr Andrea Taschetto, an Associate Professor from UNSW Science’s Climate Change Research Centre, predicted a significant downpour before Christmas.
‘Last summer was particularly unusual in that we did receive lots of rain,’ Dr Taschetto said.
‘It was the wettest and coolest summer in the past five years and that was basically because of La Nina.’
‘La Nina can sometimes persist for two years so we could see more (repeated) rainfall this summer.’

Doctor Andrea Taschetto, an Associate Professor from UNSW Science’s Climate Change Research Centre, also believes the downpour will be significant across Australia this summer

Australia’s Bureau of Meteorology declared on Tuesday a La Nina event is underway in the Pacific.
During La Nina conditions, the east to west trade winds blowing across the equatorial Pacific strengthen.
These then push rain systems westwards and raise the chance of flooding.
Recent widespread and heavy rainfalls have seen minor to moderate flooding in many inland rivers across Australia, notably in NSW.
The Lachlan River, which last week threatened the NSW central west town of Forbes and saw many locals forced to evacuate their homes after urging from the SES, still remains at major flood levels.
Another belt of rainfall is heading towards the east coast, which could see up to 60mm of rain from Queensland into Victoria in the coming days.
Additionally, WeatherZone is reporting large parts of the country have experienced between two and four times their normal November rainfall already, with another month’s worth due this week alone.
The Mackay region in Queensland will be worst affected, with extreme warnings to be in place from Wednesday to Friday.
The ACT will also be swallowed by storms, with eastern parts of South Australia to experience significant rain.
Perth is the only Australian capital city where the rain is tipped to miss.
In Sydney, umbrellas are tipped to be in vogue until at least November 28.
The Bureau of Meteorology has severe warnings in place for the area near Lockyer Valley and Ipswich for the remainder of Monday and early hours of Tuesday – with rain due to keep coming down all week

Major cities will be in the firing line on Friday, with the weather systems set to move closer to the ocean with Sydney, Brisbane, Canberra and Melbourne set to be drenched
The deluge in the Harbour City saw up to 15mm on Sunday, November 21, with BOM climatologist Agata Imielska stating there is ‘no sunshine on the forecast in the week ahead for Sydney’.
Thunderstorms are predicted over the next 48 hours, with rain of up to 20mm on November 25.
With the city’s main water catchment Warragamba Dam already 99.2 per cent full, some weather professionals are also increasingly concerned about heightened flood risks this summer.
‘What this rain is doing is keeping catchments wet across much of the state, Sydney included. Water storages are full, that could see increased flood risk,’ Ms Imielska said.
‘With saturated soils and storages being full, there’s no capacity for rivers and the broader environment to soak up that rainfall. It just means we don’t need as much rain for flooding to occur.’
