NSW firefighters are making the most of favourable weather conditions attempting to bring under control more than a dozen bushfires ahead of potentially hot temperatures next week.
About 40 fires continue to burn across the state, 13 of which remained uncontained on Friday.
"Firefighters continue to take advantage of more favourable weather to undertake back-burning across NSW firegrounds," the NSW Rural Fire Service tweeted.
"This work is being done ahead of potentially more hot and windy weather next week."
The RFS is keeping a close eye on three major blazes which caused concerns earlier in the week at Bees Nest near Armidale, Drake near Tenterfield and Shark Creek in the Clarence Valley.
All remain at Advice alert levels, along with a fire east of Glen Innes which was being fanned by strong winds on Thursday night.
Southerly winds are forecast across the fireground on Thursday, which the RFS warns will push the fire and embers towards Wytaliba.
"These embers could cause spot fires ahead of the main fire. You should be prepared to act should the fire threaten," the RFS said.
Several regions will experience very high fire danger on Friday, including the Far North Coast, New England and the Northern Slopes.
The North Coast, Greater Hunter and Illawarra regions are among those with a high fire danger rating.
Bureau of Meteorology duty forecaster Neale Fraser said while it is expected to remain dry, the weather would be "reasonably benign" in coming days.
He told AAP a high pressure system meant winds aren't going to be a factor.
He said longer-term conditions could potentially worsen towards the end of next week.
