The return of warm westerly winds and higher temperatures across NSW in the coming week is likely to push bushfire danger back to dangerous levels, the NSW Rural Fire Service says.
Fire conditions across NSW eased on Sunday, with firefighters gaining the upper hand on two blazes while another remains out of control in the state's north.
The Rural Fire Service has downgraded the alert level to advice for a fire burning in the New England region about 15 kilometres east of Glen Innes.
The out-of-control blaze has burnt more than 9000 hectares but the RFS says the threat to homes has eased and roads are reopening.
The RFS said firefighters had on Sunday completed some backburning, but the dryness of the landscape had caused spotting.
Monday's weather - with a strong wind warning forecast for Sydney, the Hunter, Illawarra, Batemans and Eden Coast, and temperatures pushing 30C - would also cause headaches for firefighters.
Favourable conditions for firefighting wouldn't return until Wednesday.
"Fortunately today we didn't have as bad a day as yesterday. Most firefighters held on their current containments," an RFS spokesman told AAP.
"(Tomorrow), it will be a problem day."
About 12 fires remain out of control across NSW.
In northern NSW's Drake, firefighters are getting control of a blaze which has burnt more than 53,000 hectares but been downgraded to advice alert level.
The Long Gully Road fire is burning north of the Bruxner Highway near rural properties on Red Rock Road and in Rover Park but the threat to homes has eased. The fire has caused the closure of parts of the highway.
Fire crews have also gained the upper hand on a bushfire burning in Bees Nest at Armidale which is at advice alert level.
The blaze has razed more than 90,000 hectares and continues to burn on multiple fronts within Guy Fawkes River National Park, Mount Hyland Nature Reserve and Nymboi-Binderay National Park.
The fire is burning close to homes with crews remaining on scene to protect properties in the area.
"There's still a lot of work to do until we get these fires under control," the RFS spokesman said.
"It will be about holding them in their current position as much as possible."
