Sydney Smoke Haze Coming, Computer Models Suggest from fires
A thick smoke haze is going to cover Sydney and surrounding areas, according to new modelling by the New South Wales Rural Fire Service.
Computer modelling by the NSWRFS indicates much of Sydney will experience thick smoke haze over the coming days.
*Updated to reflect location of fire to Putty area*
The models seem to indicate smoke haze is expected for western Sydney areas and Blue Mountains towns, with the possibility of moving over the greater Sydney region.
The Sydney smoke haze warning came later today with a prediction model change.
“Updated smoke modeling indicates that the Blue Mountains and western Sydney may be impacted by smoke tonight and into Sunday morning. This is from bush fires burning in the Putty area. Remember to only call triple zero for unattended fires.”
“A number of large fires are burning in the Mount Kaputar National Park, Barrington Tops National Park and Wollemi National Park. These fires are likely to burn for a number of weeks unless there is considerable rainfall: As a result smoke from these fires is settling across a large area.”
Earlier models said the smoke would go west, into regional NSW. However the new modelling changes that.
“Smoke model forecasts indicate that easterly winds will blow smoke from the 695 Fire, burning near Putty, and affect areas near Mudgee, Lithgow and Bathurst today with Sydney Smoke Haze, Only call Triple Zero for unattended fires.”

The NSW Health has developed a system of air quality alerts that are based on the daily air quality monitoring reports issued by the NSW Office of Environment and Heritage.
When an air quality alert has been issued for Sydney smoke haze, the Bureau of Meteorology assists in alerting the community by including the following statement in the Sydney Forecast How these levels relate to the Air Quality Index (AQI):
Poor: AQI > 100.
What people in Sydney should do if there is pollution in Sydney? – Sydney Smoke Haze
In order to limit your exposure to air pollution, there are a number of simple steps you can take such as:
Check your local air quality index (AQI) to find information on current air pollution levels in your area
Know when and where air pollution may be bad
Ozone is often worst on hot summer days, especially in the afternoons and early evenings
Particle pollution can be bad any time of year. It can be especially bad when the weather is calm, allowing air pollution to build up. Particle levels can be high near busy roads, during rush hour, and when there is smoke in the air from wood heaters, hazard reduction activities or during bush fires. Dust storms will also generate high levels of particle pollution.
Avoid exercising near busy roads and industrial areas. If you experience symptoms, or tend to be susceptible to air pollution consider the following:
Substitute your exercise with a less intense activity (e.g. walk instead of jog)
Reduce the time you are exercising outdoors
In summer, plan your most vigorous activities for the morning
See your doctor if symptoms are severe or do not settle after reducing exposure
Reduce your air pollution inside your home
Don’t smoke indoors
Regularly ventilate your home to remove indoor pollutants and build up of moisture. Turn on exhaust fans, particularly when bathing, showering, cooking, doing laundry and drying clothes.
Don’t use wood-fired stoves and wood-burning heaters (fire places) in your home if possible. If you do use a wood-burning heater, follow the recommendations on our factsheet on wood-burning heaters to minimise air pollution
Don’t use unflued gas heaters if possible. If you do use an unflued gas heater, follow the recommendations on our factsheet on unflued gas heaters
Install a kitchen exhaust fan above your gas cook top if possible
Consider limiting burning candles and incense
Don’t use ozone generators for managing indoor air pollution or odour problems. Read our factsheet on ozone generators.
If you suffer from asthma, other respiratory conditions such as chronic bronchitis (also called chronic obstructive pulmonary disease or COPD), or cardiovascular disease, make sure you have your reliever medicine handy. For more information please see the section ‘Who is affected by air pollution?’
