Air quality today

The air quality in A Coruña is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 3.2 µg/m³ and a PM10 reference value of 4.0 µg/m³, based on 19 valid observations collected via OpenAQ.

Overall conditions meet the Good category criteria according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for A Coruña contains measurements for carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). In total 34 rows of data have been collected from four monitoring stations, all supplied through the OpenAQ platform.

Most pollutants show very recent updates: CO, NO₂, PM₁₀, PM₂.₅, SO₂ and O₃ were last recorded on 2026‑02‑09 at 15:00 UTC, indicating that fresh information is available for these six substances. The only older entry is NO, whose most recent value dates back to 2024‑03‑01 at 00:00 UTC, so the coverage for this gas is less current than the rest of the suite.

The observed values span a wide range across the city. CO varies from a low of 110 µg/m³ up to a high of 220 µg/m³, with a median around 170 µg/m³; NO₂ ranges between 6 and 85 µg/m³, centred on a median of 25 µg/m³; PM₁₀ values sit from 4 to 31 µg/m³ (median 14), while PM₂.₅ runs from 3.2 to 13 µg/m³ (median 5.15). SO₂ is measured between 1.7 and 5.3 µg/m³ (median 3.9) and O₃ shows a minimum of 7.7 rising to 52 µg/m³, with the same figure as its median. The ten‑percentile figures are close to the minima for most pollutants, whereas the ninety‑percentile values approach the maxima, highlighting that extreme readings are not rare.

Overall the dataset provides a fairly complete picture of A Coruña’s air quality for most pollutants, but the older NO data and the limited number of stations mean that spatial and temporal variations may not be fully captured. Users should keep in mind that conditions can differ across neighbourhoods and over time, especially for the less‑frequently updated gases.
