A new health warning has been released as thick smoke from prescribed burns has seen Sydney’s air quality rise to ‘hazardous’ levels.

The smoke this morning is so thick that the city skyline is barely visible.

It is also enveloping our west, after the Blue Mountains and Newcastle both had major hazard reduction burns on Tuesday.

NSW’s Office of Environment has labelled Sydney’s air quality “poor” and is warning anyone with health issues to remain indoors.

As a result, other planned burn offs are now postponed.

NSW Rural Fire Service is warning residents the smoke will remain until at least tomorrow morning in some parts.


In some good news, the air over central Sydney is expected to clear slightly by this afternoon.

NSW Health Director of Environmental Health Dr Richard Broome told 9 NEWS:

“People with conditions like asthma, emphysema and angina are more likely to be sensitive to the effects of smoke,”

“Smoke from hazard reduction burns can be quite unpredictable, but we’re expecting poor air quality in a number of places across the Sydney basin into Wednesday morning.”

“For most people, smoke will be no more than an irritation.”

“However, I recommend that people with existing heart and lung conditions should avoid outdoor physical activity when there’s smoke around.”


Sydney is basking in unseasonly warm weather, with the temperature expected to hit a top of 25 degrees on Wednesday.
