El Nino can bring drying conditions to south-eastern Australia and this year areas of Victoria have been hardest hit.

Seasonal Risk Agronomist with Victoria's Department of Economic Development, Dale Grey, who studies weather patterns and impacts for agriculture said El Nino loomed large over spring in the state.

"It has been dry, but if you're in New South Wales, or other parts of Australia, you're probably thinking, 'what El Nino?'

"So this El Nino sort of has been a personal one just for Victoria."

He believes the current El Nino is peaking now but will continue through to April.

"Having a fully fledged El Nino for the next couple of months, doesn't really mean anything," Mr Grey said.

"Historically (in summer) a third of our El Nino's can be quite wet, a third can be normal in terms of rainfall and a third can be drier than normal."

El Nino isn't the only weather phenomena that weather watchers are keeping an eye on.

Record warm temperatures in the Indian Ocean are being observed, as they have potential to bring more rainfall to parts of Australia.

"All year the Indian Ocean as a whole has been warmer than normal and for the last couple of months now it's been warmest on record," Mr Grey said.

"Anytime you've (got a) warmer than normal tropical ocean it has to be evaporating records amounts of moisture by definition."

As to where the water will go, different weather models are predicting different outcomes.

Some weather models forecast the moisture to miss Australia, while others suggest south-east Queensland will receive extra moisture, and some models forecast it will be received in Victoria, Western Australia and Queensland.
