Air quality today

The air quality in Igualada today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 7.0 and a PM10 reference value of 7.0, based on eleven valid observations collected via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the provided assessment. 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 Igualada contains measurements for eight pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). These values come from 14 individual data rows collected at two monitoring stations in the city.

Most of the recent readings were uploaded on 2026‑02‑10 02:00 UTC, giving a snapshot that is only a few days old for NO, NO₂, O₃, PM10, PM2.5, SO₂ and NOX. The CO measurement is older, last updated on 2023‑12‑12 07:00 UTC, so its figure reflects conditions from more than a year ago. Across the pollutants, the observed concentrations are fairly narrow. CO is reported at a single value of 400 µg/m³, while NO stays constant at 1 µg/m³. NO₂ varies between 7 and 12 µg/m³ with a median of 9.5 µg/m³; O₃ ranges from 19 to 77 µg/m³ (median 48 µg/m³); PM10 is between 5 and 7 µg/m³ (median 6 µg/m³); PM2.5 is a steady 7 µg/m³; SO₂ spans 4 to 6 µg/m³ (median 5 µg/m³); and NOX is recorded at a single value of 13 µg/m³.

The coverage is uneven: while most pollutants have fresh data from the same recent timestamp, CO’s information is outdated, and several pollutants (NO, NO₂, O₃, PM10, PM2.5, SO₂, NOX) each have only one or two rows, limiting insight into temporal variation. Consequently, the dataset gives a concise but limited picture of air quality in Igualada at a specific moment, and conditions can differ across locations and times not captured here.

Data notes

The data shown for Igualada are based on eleven valid measurements and were refreshed within three days, with the latest update recorded at 2026‑02‑10T02:00:00+00:00. This snapshot reflects conditions captured by the monitoring network at that time; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment within the city.
