Air quality today

The air quality in Adelaide today is classified as Good. The primary pollutant measured is PM2.5. The latest reading shows a PM2.5 concentration of 4.24 µg/m³. This value is based on five valid measurements. A total of five monitoring stations contributed data to this assessment. The observed PM2.5 level aligns with the thresholds that define the Good category. The data snapshot corresponds to 2026-02-12 00:00 UTC.

PM10 data is not available for this assessment. Data is shown via OpenAQ. The measurement reflects fine particle concentrations at ground level across the metropolitan area. No other pollutants met the criteria to be listed as the primary concern in this report. All values are derived from the OpenAQ network of sensors. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Adelaide air‑quality feed pulls data from nine monitoring sites, giving a total of 47 recent rows. The dataset includes measurements for PM2.5, PM10, PM1, NO₂, O₃, temperature, relative humidity and particle count (UM003). Sensors for carbon monoxide (CO) and sulphur dioxide (SO₂) are listed among the city’s monitored pollutants, but no recent rows for those gases appear in the current export.

Across the pollutants, the most up‑to‑date observations are from 10 February 2026 22:00 UTC (PM2.5, PM1, relative humidity, temperature and UM003). The PM10 values are from 13 January 2025 23:00 UTC, while NO₂ and O₃ are dated 16 March 2024 07:00 UTC, indicating that a large share of the rows (42 of 47) are older than three days. Median concentrations show a modest spread: PM2.5 sits at 5.6 µg/m³ with a range of roughly 1 to 9 µg/m³; PM10’s median is 15.5 µg/m³ ranging from about 1.2 to 21 µg/m³; NO₂ averages 0.018 ppm between 0.002 and 0.022 ppm; O₃ averages 0.005 ppm with a low of 0 and a high of 0.025 ppm. Temperature readings centre on 23.7 °C, spanning from –2.2 °C to 29.1 °C, and relative humidity clusters around 32.6 % (26.96 %–35.13 %). Particle counts (UM003) have a median of 412 particles/cm³, ranging from 260 to 672.

These figures illustrate that while Adelaide’s dataset provides recent detail for several key particulates and meteorological variables, the coverage for gaseous pollutants is older and less frequent. Consequently, city‑wide conditions can differ noticeably across locations and times, especially for the pollutants with stale timestamps.
