This month's record breaking rain has made it difficult to get machinery out onto paddocks and a hailstorm on Sunday night caused damage to some fruit.

Orchardist Guy Gaeta said he was fortunate to have received only "sprinkle" of hail at his Nashdale property on Sunday night.

"I think we dodged a bullet," he said.

Others didn't fare as well, however, with one grower saying much of his fruit would now be marked.

Wet weather during the harvest next month will be the next big threat, with the possibility of losses due to fruit splitting.

Paula Charnock of Nashdale's Thornbrook Orchard said the recent heavy rain had already caused her early varieties to split.

"If we get a bit more rain the next ones are likely to split as well," she said.

She's had to delay the opening of her orchard's pick-your-own system for tourists that usually begins at the end of the month.

"We were hopeful that we might open the end of November but those cherries have all split, so at this stage we're looking at the week after," she said.

The wet also brings disease pressures.

Orange has had its wettest November in more than 130 years, with 220mm rain so far and more predicted this weekend.

Mr Gaeta said the rain was "better now than in three or four weeks time" when much of the fruit is nearing maturity.

"That's when you've got a lot of problems," he said.

Some warm and dry weather is now at the top of his wish list.

"The fruit's not even growing because it's so cold," Mr Gaeta said.

"We need to get some warmth and some growth into the cherries."

Orange grower and President of the NSW Cherry Growers Association Fiona Hall said her biggest problem now was getting machinery out.

"We can't even get a tractor on the paddock. We can't spray, we can't get the hail nets out because it's so wet and some of our blocks are steep."

The heavy rain itself would have little impact on the crop itself, as it was still so green, "but we wouldn't want this weather in a month's time," she said.

Mrs Charnock from Thornbrook Orchard said she remained optimistic.

"Hopefully summer will come and do what it's supposed to do and the mid and late season cherries will be OK."

"Cherries are a day-by-day thing. We'll just have to wait and see."
