Air quality today

The air quality in Tarragona today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements recorded by OpenAQ show a PM2.5 reference value of 6.0 and a PM10 reference value of 6.0, based on 19 valid observations. These figures reflect the current monitoring results for the city.

What the data includes

The dataset for Tarragona currently contains measurements from four monitoring sites, providing a total of twenty‑one individual rows of data. All eight pollutants tracked by the OpenAQ network are represented: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), ozone (O₃), sulfur dioxide (SO₂), and the two particulate fractions PM1 and PM10. The most recent observations for every pollutant were recorded on 2026‑02‑10 at 03:00 UTC, so the freshest data are less than a day old.

Across the city’s stations the values show limited variability. For gases measured at the Parc de la Ciutat site, NO is consistently reported at 1.0 µg/m³, with a narrow range from 1.0 to 3.0 µg/m³; the median of 1.0 µg/m³ sits near the lower end of that spread. NO₂ and NOX show broader but still modest ranges – NO₂ varies between 6.0 and 16.0 µg/m³ with a median of 10.0 µg/m³, while NOX spans 7.0 to 17.0 µg/m³ and averages 12.5 µg/m³. SO₂ is recorded at values from 1.0 up to 3.0 µg/m³, with the most recent reading of 3.0 µg/m³ matching its maximum observed level.

The particulate matter measurements come from the Bonavista site and are single‑point entries: PM1 is reported as 5.0 µg/m³ and PM10 as 6.0 µg/m³, each with no observed variation in the current dataset. CO and O₃ also appear as single values – 200.0 µg/m³ for CO and 39.0 µg/m³ for ozone – both recorded at the Parc de la Ciutat location on the same timestamp. Because many pollutants have only one row of data, the overall picture is limited; conditions can differ across neighbourhoods and times, so the available figures represent a snapshot rather than a comprehensive view of Tarragona’s air quality.

Data notes

The data shown for Tarragona reflects 19 valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T03:00:00+00:00. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
