Air quality today
Today the air quality in Townsville, Queensland is classified as Good according to the Duck score assessment. The primary pollutant measured is PM2.5, with a reference concentration of 7.2 micrograms per cubic metre. The accompanying PM10 reference value is 17.8 micrograms per cubic metre, reflecting the latest available readings.
Today, the valid measurement count is two, representing the number of observations used in the current assessment. The values are currently expressed in micrograms per cubic metre. Data is shown via OpenAQ, a global open air quality platform that provides free public access to monitoring results. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Townsville pulls in four measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10), particulate matter up to 2.5 µm (PM2.5) and sulphur dioxide (SO2) – from a single monitoring station that contributes eight individual rows of observations. Of those rows, two are recorded within the last three days while the remaining six are classified as old, meaning the most recent timestamps for NO2 and SO2 date back to 2019‑05‑21 03:00 UTC, whereas the latest entries for PM10 and PM2.5 are from 2026‑02‑10 22:00 UTC.
Across the pollutants the recorded values show modest variation. NO2 and SO2 each range from 0.0 to 0.001 ppm with a median of 0.0005 ppm, indicating a very narrow spread. PM10 values sit between 12.0 and 17.8 µg/m³, with a median of 14.9 µg/m³ and a 10th‑percentile of about 12.6 µg/m³, while PM2.5 spans 4.6 to 7.2 µg/m³, median 5.9 µg/m³ and 10th‑percentile near 4.86 µg/m³. The recent updates for the particulate matter measurements suggest the freshest snapshot of Townsville’s air quality, but the older timestamps for the gaseous pollutants mean that current conditions for NO2 and SO2 are not directly represented in the dataset.
Overall the coverage is limited to one site, and the data are unevenly distributed in time: only the particulate matter series provide near‑real‑time information, whereas the gas‑phase readings rely on data that are several years old. Consequently, while the available numbers give a sense of typical ranges for each pollutant, they do not capture the full spatial or temporal variability that can occur across Townsville.
