It's no surprise given the fire situation across the state, but the mountains was hit by lsmoke again on Sunday.
The situation began to improve mid-morning but it wasn't a great start to the day.
"The air is not as bad now as it was earlier. It's breathable now," Lorraine, who emailed us with these photos, wrote.
"But smoke haze well and truly back - in front room of the Blue Mountains Backpackers right now and the view just across the road the railway station behind the trees is all smoke haze again."
