Cowra and the surrounds recorded almost 50 mils of rain at the end of January but local agronomist Peter Wilson says it has been patchy across the region.

"North of Cowra has received significantly more rain than the Cowra Airport," Mr Wilson said.

"There have been some quite extreme weather conditions and storm-dominant rainfall."

Mr Wilson says some farmers have seen 100-120mm of rain this year, which has helped with crop and livestock production.

"We are seeing rejuvenation in lucerne hay and producers have been able to finish off lambs," he said.

"Most importantly, farmers have been able to start conserves into cropping paddocks and commence stubble spraying."

Billimari farmer Chris Groves, who has received close to 50mms for the month, said Canowindra farmers had received the most rain in the area.

"Any rain is good," Mr Groves said.

"It freshens up the summer feeds in pasture country."

Mr Groves said the rain has resulted in farmers having to manage soil moisture.

"Farmers are so much smarter now," he said.

"It adds to the cost of cropping operations because we have to use herbicide but any rain is useful for winter crop establishment."

Mr Wilson warns the rest of Summer could have a more negative outlook due to the extremes in daily weather.

"There's still a deal of caution out there considering we still have to get through February."

Mr Groves says there have also been an increased number of reports of Barber's Pole Worm in the district.

"We manage for it and conduct drenching accordingly," he said.

"But there is a lot of it about."

Mr Wilson said a lowered fire risk has been the biggest positive during the season.

"Green pasture paddocks are always a concern," Mr Wilson said.

"December was very dry and we very lucky we haven't had any major fires."
