The weather bureau is predicting a big change in Australia's forecast this summer, with an El Nino no longer expected.

Average rainfall is predicted in the coming months in the absence of El Nino - Australia's major weather pattern in the 21st century which brings drought-like conditions.

The chief climate forecaster says it is the biggest turnaround in weather patterns since records began.

"Come September, all of a sudden, the temperature started to cool down, the trade winds started to become a little bit enhanced, and the cloud patterns and other indicators like that headed away from El Nino," the bureau's manager of climate prediction services, Dr Andrew Watkins, said.

"So this is what we're looking at as climatologists, giving us the heads up about what may happen over the next few months, and indeed what we're seeing now is a backing off from those El Nino thresholds."


Dr Watkins says they are not sure why there has been a cooling down.

"It actually is quite a unique situation if we end up not going into an El Nino event," he said.

"It'll sort of be the biggest turnaround that we've actually seen in our records going back to about 1950, so quite unprecedented."
