It ' s over . La Niña and the wetter-than-usual weather it typically brings to large parts of Australia is officially behind us .

The U . S . Climate Prediction Center ( CPC ) was the first to declare that the 2022 / 23 La Niña had ended , paving the way for a return of drier and warmer weather in Australia .

Australia ' s Bureau of Meteorology came to the party .

" La Niña has ended in the tropical Pacific Ocean . The El Niño – Southern Oscillation ( ENSO ) is now neutral ( neither La Niña nor El Niño ) with oceanic and atmospheric indicators having returned to neutral ENSO levels ," the BoM announced earlier this month .

The BoM went on to say that neutral conditions are expected to persist through autumn , however there are signs that El Niño could form later in the year .

Indeed the BoM has issued an El Niño Watch , which means a 50 % chance of an El Niño in 2023 .

El Niños typically bring drier , warmer weather than usual across Australia , and in the past have contributed to some of the country ' s worst droughts .
