More of the western region is slipping closer to drought.
Around 47 per cent of the state is now declared 'marginal' which is an increase of about 17 per cent in the past month.
The Department of Primary Industries says conditions have worsened in the north and central west as well as the Darling and Lachlan areas.
The agricultural protection officer Simon Oliver says the hot and dry spring is affecting pastures.
"This spring's been extremely dry in a lot of areas," he said.
"Some people have been fortunate to get some decent rain through some storms events but general rain has been very low right across the area."
Mr Oliver says it is hoped there will be more rain during summer than previously expected.
"They were forecasting a hotter and drier summer period.
"It seems to have come back a bit to more average but we haven't seen anything near average at the moment, we've just had a heatwave quite early in the summer period.
"I guess we're optimistic that we get rain."
