Air quality today

The air quality in Mataró today is classified as Good. The primary pollutant measured is PM2.5, fine particulate matter, and the latest data show a reference value of 4.0 µg/m³ for PM2.5 alongside a reference value of 5.0 µg/m³ for PM10. A total of eight valid measurements were recorded to determine these values.

Data is shown via OpenAQ and reflects the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality dataset for Mataró currently contains eight measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). All of these values are reported from a single monitoring site, the Passeig dels Molins station, so the spatial coverage across the city is limited to one location.

Every pollutant in the set was last updated on 2026‑02‑10 at 03:00 UTC, which falls within the “updated within 7 days” freshness bucket. The data show a striking uniformity: for each contaminant the minimum, median and maximum values are identical, indicating that only one measurement per pollutant is currently available. CO registers 200 µg/m³, NO 1 µg/m³, NO₂ and NOX both 5 µg/m³, O₃ 56 µg/m³, PM10 5 µg/m³, PM2.5 4 µg/m³ and SO₂ 1 µg/m³. Because there is no spread in the reported figures, statistical summaries such as percentiles (10th and 90th) all match the single observed value.

With eight pollutant rows but only one station, the dataset provides a snapshot rather than a comprehensive picture of air quality throughout Mataró. The freshness of the timestamps suggests recent data, yet the lack of multiple observations limits insight into temporal variation or differences between neighbourhoods. Users should keep in mind that conditions can differ across the city and over time, and the current figures represent only what was recorded at the Passeig dels Molins site on the specified date.

Data notes

The data shown are based on eight valid measurements and were refreshed recently, updated within 3 days (last update: 2026‑02‑10T03:00:00+00:00). This snapshot reflects conditions recorded at the monitoring sites during that period. Air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Mataró.
