There are more than 80 fires burning across the state, with two fires remaining at emergency warning levels. Meanwhile, 16 fires are at watch and act levels.
The Bureau of Meteorology's forecaster Abrar Shabre said while there will be an increase in humidity on Sunday and Monday, it's likely to become dry again on Tuesday.
"We're not expecting any rain for the next four or five days," he said.
But he said from Tuesday onwards there is an increasing likelihood of fires in other parts of the state.
"The dry conditions, with higher temperatures and lower dew points will have elevated fire danger, not just for the North Coast, but for large parts of NSW."
NSW RFS Commissioner Shane Fitzsimmons said little reprieve in fire conditions could be expected over the next week or throughout the summer months of December, January and February.
"The forecast for the balance of the season continues to be driven by above-normal temperatures (and) below-average rainfall to dominate over the coming months," Mr Fitzsimmons said.
