Air quality today

The air quality in Canberra today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). The PM2.5 concentration is 4.3 µg/m³ and the PM10 concentration is 9.7 µg/m³. Both values are expressed in micrograms per cubic metre. Four valid measurements were used in this assessment.

Data is shown via OpenAQ. The reported figures reflect the current ambient conditions captured by the monitoring network. The dataset includes recent observations that meet quality criteria. No additional pollutants dominate the measurement set. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Canberra includes five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). All values come from a single monitoring location identified as Civic, which supplies eight rows of data overall. The freshness profile shows that four of those rows were recorded within the last three days, while the remaining four are classified as old, with the most recent timestamps dated 2026‑02‑10 21:00 UTC for O₃, PM10, PM2.5 and CO, and an older entry for NO₂ on 2025‑03‑05 20:00 UTC.

Ozone values are tightly clustered, ranging from 0.009 ppm at the low end to 0.023 ppm at the high end, with a median of 0.016 ppm and a 10‑90 percentile spread of 0.0104‑0.0216 ppm. Particulate matter shows a similarly narrow spread: PM10 varies between 9.6 µg/m³ and 9.7 µg/m³ (median 9.65 µg/m³, 10‑90 percentile 9.61‑9.69 µg/m³), while PM2.5 ranges from 3.7 µg/m³ to 4.3 µg/m³ (median 4.0 µg/m³, 10‑90 percentile 3.76‑4.24 µg/m³). Carbon monoxide is reported as 0.0 ppm across all recent rows, indicating no detectable concentration at the monitoring site during the recorded periods. In contrast, nitrogen dioxide is represented by a single value of 28.155 ppm, and because it originates from an older record, it highlights an uneven temporal coverage across pollutants.

Overall, the data set provides a concise snapshot of air quality at one central location in Canberra, with half of the observations being recent and the other half dated beyond a year. The narrow numeric ranges suggest limited variability at the Civic site during the recorded intervals, but the reliance on a single station and the older NO₂ entry mean that conditions elsewhere in the city or more current NO₂ levels may not be captured.

Data notes

The dataset includes four valid measurements and is updated within 3 days, with the most recent reading recorded at 2026-02-10T21:00:00+00:00. These values represent a snapshot of ambient conditions across Canberra and are intended for general informational use. Air quality can vary by location and time within the city, so conditions at any specific site may differ from the reported figures.
