Track Air Quality

Track Air Quality

Smoke is made up of hundreds of different gases and small particles, also known as particulate matter or ‘PM’. PM2.5 is the name given to the very small particles which can cause health problems. These are less than 2.5 micrometres in size, about 1/25th the width of a human hair. The amount of PM2.5 in the air is the best indicator of how much smoke is in the air. You can find out more about these particles at the Environment Protection Authority

The Environment Protection Authority (EPA) monitors these particles in many places across Tasmania. This information is shown in the map below and is updated every 10 minutes.

The EPA also provide an alternative accessible version of EPA Tasmania PM2.5 data, in micrograms per cubic metre. This listing is alphabetical by station and includes date, time, current PM2.5, Hour-average and category.

To see your local air quality, find your nearest location on the map below. Match the colour of this location to the table at the bottom of this page. For more information, see the Bushfire smoke and your health fact sheet

You can also download AirRater, a free smartphone app. AirRater provides air quality information from the EPA network and estimates air quality in places without an air monitoring station. For more information and to download the app, visit AirRater

Indicative real-time Tasmanian air Quality data. An alernative accessible version of this information can be access from the link below this map

Smoke concentrations can vary from place to place and change quickly. Sometimes the air quality displayed for your nearest EPA monitor or shared via the AirRater app could be different to the conditions you are experiencing. The table below is a guide to the expected conditions at different concentrations of PM2.5 (rolling hourly average).

PM2.5

What the conditions are like

What this means

0-9

Good

0-9 Good

Beautiful. In many parts of Tasmania background PM2.5 is less than 5 and hard to beat.

Enjoy the outdoors.

10-24

Fair

10-24 Fair

Generally good, it might appear a little hazy.

This could indicate that air quality is beginning to get worse. Keep an eye on conditions. If the smoke has been much worse and is now improving, this is a good time to open and air your house.

25-99

Poor

25-99 Poor

Generally you are able to see or smell smoke in the air when PM2.5 is over 25.

The smoky air could worsen the health of people at higher risk from smoke. People at higher risk from smoke should consider taking action. For more information about what you can do, see the Bushfire smoke and your health fact sheet

100+

Very Poor

100+ Very Poor

It will likely be very smoky and unpleasant for everyone.

This represents severe air pollution. People at higher risk from smoke should take action to manage any health conditions and reduce the amount of smoke they breathe. For more information about what you can do, see the Bushfire smoke and your health fact sheet

In general, if PM2.5 levels are poor or very poor and have been for some time, it is more important to take action. Poor air quality for several days has a greater health impact than a brief episode lasting a few hours. For more information, see the Bushfire smoke and your health fact sheet. The higher thePM2.5 the more likely this is to happen.
