Air quality today

The overall air quality today in the City of Cockburn, Western Australia, is classified as Good. The main pollutant measured is PM2.5 (fine particles).

Data is shown via OpenAQ and five valid measurements were recorded during the latest monitoring period. The most recent PM2.5 reading is 2.71 µg/m³, which corresponds to the Good air‑quality category. No PM10 value is available for this period. The reference value for PM2.5 is 2.706 µg/m³, close to the observed reading. This reference helps to contextualize the measured concentration. Five data points contributed to the reported average.

What the data includes

The City of Cockburn data set pulls OpenAQ readings from two monitoring stations, giving a total of twelve recent rows of information. All six measured pollutants are represented: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. For most variables the newest observation was recorded on 2026‑02‑10 at 22:00 UTC, showing that the data are generally refreshed within the last three days. The exception is PM10, whose latest entry dates back to 2025‑01‑13 at 23:00 UTC, indicating that this particular metric is older and may not reflect current conditions.

Across the dataset the observed ranges are modest. PM1 values span from 0.006 µg/m³ up to 1.464 µg/m³ with a median of 0.735 µg/m³, while PM2.5 ranges from 0.064 µg/m³ to 2.706 µg/m³ and centers around a median of 1.385 µg/m³, suggesting a broader spread for the finer particles. PM10, although based on older data, varies between 1.761 µg/m³ and 2.757 µg/m³ with a median of 2.259 µg/m³. Relative humidity recorded at the single site moves from 29.4 % to 50.6 % (median 40.0 %), and temperature ranges from 20.09 °C to 26.12 °C (median 23.10 °C). The UM003 particle count shows the widest absolute variation, from 107 particles/cm³ to 428 particles/cm³, with a median of 268 particles/cm³.

Because all measurements come from the Aubin Grove location, spatial coverage is limited to that neighbourhood, and the older PM10 record highlights an uneven update frequency across pollutants. Consequently, while the data give a recent snapshot of air quality for Cockburn, conditions can differ in other parts of the city and the older PM10 values should be interpreted with that limitation in mind.
