Mr. Duck’s Air Quality Score
Good air today for Cádiz, Andalusia, Spain
This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Cádiz today is classified as Good. The primary pollutant identified is PM10, with a measured reference value of 32.0 µg/m³ based on four valid observations recorded by OpenAQ.
These measurements indicate that the concentration of coarse particulate matter remains within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Cádiz includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO₂). All values come from a single monitoring station located on AVDA. MARCONI, so the coverage is limited to one site but provides a complete set of these six compounds.
The most recent observations are fairly fresh for four of the pollutants: NO₂, O₃, PM10 and SO₂ were all recorded on 2026‑02‑09 at 12:00 UTC, which falls within the last seven days. In contrast, CO was last updated on 2025‑12‑03 at 10:00 UTC and NO on 2024‑02‑21 at 00:00 UTC, making those two readings considerably older. Across the six rows, the median values are identical to the minimum and maximum for each pollutant – CO sits at 18 µg/m³, NO at 4 µg/m³, NO₂ at 7 µg/m³, O₃ at 61 µg/m³, PM10 at 32 µg/m³ and SO₂ at 2 µg/m³ – indicating no observed variation within the available data.
Because only one station contributes all rows, spatial variability across Cádiz cannot be captured; conditions may differ in other neighborhoods or at different times. Moreover, the older timestamps for CO and NO mean that recent trends for these gases are not reflected in the current dataset, while the newer measurements give a more up‑to‑date picture of NO₂, O₃, PM10 and SO₂.

Data notes
The current dataset for Cádiz includes four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑09T12:00:00+00:00. These values represent a recent snapshot of ambient air quality across the city, but conditions can differ by neighbourhood and change throughout the day, so local variations may not be captured in this summary.
