The current climate event is known as negative Indian Ocean Dipole, which the Bureau of Meteorology announced this week.

A negative IOD increases the likelihood of above average winter to spring rainfall for much of southern and eastern Australia.

For the first 24 days of this month, Ballarat has had only four days without rainfall totaling 79.8 millimetres, which is above the average of 65.5 millimetres for the month.

Ballarat recorded 87.8 millimetres of rainfall in June, 14.4 millimetres above the 73.4 millimetre average.

Two of the Ballarat region's farmers said they were experiencing one of the wettest winters since the past few decades.

Burrumbeet farmer Doug Hobson, who has experienced prolonged winters during the 1960s to 1980s and the past decade, said his crops were hanging in alright.

He said he was using helicopters and aeroplanes to spread fertilisers, mainly urea, because some paddocks were not trafficable and it avoided getting bogged.

"There's obviously some lower patches which are going to be affected but we are lucky enough at the moment that we have had them (crops) well fed up and, right at the moment, we are doing some aerial spreading with field air," Mr Hobson said.

"There are some paddocks that aren't trafficable but overall they are handling it all at the moment but we would like to see the days lengthen out the weather warm up a little more, get a little bit more sunshine to get a little bit more drying and a little bit more growth."

Tourello farmer Steve Kinnersly likened the current wet winter period to winters he experienced 20 years ago.

"Yes it's wet, but this is what we signed up for. We like to see a wet winter to try and shore up our spring. If we have a dry winter and a short spring, then that can be quite perilous too," Mr Kinnersly said

Mr Kinnersly said he was fortunate enough to get his crop in and urea spread early because the paddocks were now so wet.

"So we will sit and wait until we can get reasonably back in paddocks again for a final top up to try and lift them back out of their winter doldrums," he said.

Mr Kinnersly said he could get into his paddocks if he absolutely had to but he would make a mess so he would wait until the final top-up.

He said one advantage farmers could look forward to was good grain and livestock commodity prices.

"Realistically, as a farmer we can be optimistic with the grain prices they way they are, livestock prices they way they are," Mr Kinnersly said.

Bureau of Meteorology climatologist Jonathan Pollock said there was a high chance the eastern two-thirds of Australia would be wetter than the average this August to October due to the negative IOD.

He said in Ballarat, there was about a 71 per cent chance the city could have more rainfall than usual.

"The further north you go from Ballarat, the higher those chances get, and the further south you go, those chances reduce as well," Mr Pollock said.

"It's a wet outlook for Australia because of that negative Indian Ocean Dipole and it's likely we will get some of that wet weather extending as far down as central Victoria.

"At the same time, temperatures are likely to be warmer than usual for August to October."
