Air quality today
Today the air quality in Mount Isa, Queensland is classified as Good. The primary pollutant measured is PM2.5. The most recent observations, recorded on 2026-02-12 06:00 UTC, show a PM2.5 concentration of 6.1 µg/m³ and a PM10 concentration of 14.0 µg/m³. These figures are based on two valid measurements and are displayed via OpenAQ.
Both measured concentrations fall within the range that defines the Good category, and no additional interpretation is provided. The dataset reflects ambient conditions at the time of measurement and does not include any extrapolated values. No other pollutants were reported above the threshold for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Mount Isa includes three measured pollutants – particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulphur dioxide (SO₂). All values come from a single monitoring location identified as The Gap, so the station count is one, but the raw data contains five rows. Of those rows, two have been updated within the last three days, while the remaining three are classified as old, meaning the overall freshness is mixed and a substantial portion of the records are not recent.
For PM10 the recorded values are tightly clustered: the minimum is 14.0 µg/m³, the median 14.15 µg/m³ and the maximum 14.3 µg/m³, giving a total spread of only 0.3 µg/m³ and a 10th‑percentile of 14.03 µg/m³ versus a 90th‑percentile of 14.27 µg/m³. PM2.5 shows a broader distribution, ranging from 3.8 µg/m³ up to 6.1 µg/m³, with a median of 4.95 µg/m³; the inter‑percentile range (4.03 µg/m³ to 5.87 µg/m³) indicates more variability than PM10. The SO₂ readings are all listed as –9999.0 ppm, and the most recent timestamp for this pollutant is from 2019‑05‑21 03:00 UTC, signalling that no current SO₂ measurements are available for the city.
These points illustrate that while recent PM10 and PM2.5 data are present and fairly detailed, the coverage is limited to a single site and the dataset contains a notable share of outdated rows. The absence of up‑to‑date SO₂ information further highlights gaps in the pollutant monitoring portfolio for Mount Isa, meaning that conditions can differ across the city and over time beyond what the current data capture.
