Special NSW Bush Fires announcement

Note that the NSW Environment agency only reports the PM2.5 level as a 24 hour average, which can make it really difficult to find out what the actual air quality is in real time. However, since visibility is also reported as a 1 hour average, and it is a much better metric for determining the real time quality of the air, the AQI calculation has been updated to take into account the visibility.

Values are converted to the US EPA AQI standard.

For instance, the PM2.5 24 hour average can be Good in Sydney, but the Visibility could be well past Hazardous. In this case, it would take several hours for the PM2.5 24 hour average to report as hazardous because there could have been a fairly good air quality over the last 24 hours and only just recently has the wind started to blow the smoke towards Sydney.

AQIAir Pollution LevelHealth ImplicationsCautionary Statement (for PM2.5)
0 - 50GoodAir quality is considered satisfactory, and air pollution poses little or no riskNone
51 -100ModerateAir quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
101-150Unhealthy for Sensitive GroupsMembers of sensitive groups may experience health effects. The general public is not likely to be affected.Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
151-200UnhealthyEveryone may begin to experience health effects; members of sensitive groups may experience more serious health effectsActive children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
201-300Very UnhealthyHealth warnings of emergency conditions. The entire population is more likely to be affected.Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
