Air quality today

The air quality in Bunbury, Western Australia is classified as Good. The main pollutant measured today is PM2.5. The observed PM2.5 concentration is 0.88 µg/m³, matching the reference value of 0.88 µg/m³. Data for PM10 is not available. Air quality data is shown via OpenAQ. The concentration is reported in micrograms per cubic metre. These values are derived from the latest available monitoring data.

Five valid measurements were used to generate this assessment. This assessment reflects the current monitoring period. All values are presented without interpretation. The dataset includes five individual readings collected today. Each reading contributes to the overall category determination. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Bunbury air‑quality feed draws from a single monitoring site, giving a total of six data rows. Five of those rows were recorded within the last three days, while one row is classified as old data, dated 2025‑01‑13. This means that most of the recent measurements are fresh, but the overall picture is limited to a single location and a small number of observations.

The dataset includes six measured variables. PM1 is reported at 0.172 µg/m³, PM2.5 at 0.883 µg/m³, and PM10 at 0.474 µg/m³. Relative humidity stands at 38.84 %, temperature at 22.35 °C, and particle count (UM003) at 223.39 particles/cm³. For each of these pollutants the minimum, median and maximum values are identical, indicating no observed spread across the available rows. The most recent timestamps for PM1, PM2.5, relative humidity, temperature and UM003 are all from 2026‑02‑10 22:00 UTC, whereas the PM10 value comes from the older 2025‑01‑13 23:00 UTC record.

Because the data originate from only one station, spatial variation across Bunbury cannot be captured, and the single older PM10 entry highlights uneven temporal coverage among the pollutants. While the recent readings give a snapshot of current conditions at that site, the city’s air quality can differ in other neighborhoods and at other times. Users should keep in mind that the limited number of rows and the reliance on a single sensor constrain how fully the dataset reflects the broader atmospheric environment in Bunbury.
