Air quality today

The air quality in Vitoria‑Gasteiz is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measured concentrations are 7.0 µg/m³ for PM2.5 and 7.0 µg/m³ for PM10. These concentrations are expressed in micrograms per cubic metre. The values are within the reference limits used for assessment.

Vitoria‑Gasteiz lies in the Autonomous Community of the Basque Country in Spain. This assessment is based on 11 valid measurements collected through OpenAQ. The reported figures are presented without adjustment and represent the latest available data for the city. Data is shown via OpenAQ. The measurement count reflects the number of valid observations used in the current evaluation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Vitoria‑Gasteiz brings together measurements from five monitoring stations, amounting to twenty‑four individual rows of data. Six pollutants are represented: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulfur dioxide (SO₂). Each pollutant is reported in micrograms per cubic metre (µg/m³) and the most recent timestamps are shown in UTC. For CO, NO₂, PM10, PM2.5 and SO₂ the latest update is 2026‑02‑09 15:00 UTC, while the NO values were last refreshed on 2024‑01‑16 23:00 UTC. Overall, twelve rows are dated within the past thirty days and the remaining twelve are older, indicating that half of the records reflect conditions that are not current.

The range of values varies across the pollutants. NO₂ values span from 14 µg/m³ up to 46 µg/m³ with a median of 17 µg/m³; PM10 ranges between 4 µg/m³ and 25 µg/m³, median 7 µg/m³; PM2.5 runs from 2 µg/m³ to 13 µg/m³, also median 7 µg/m³; CO shows a broader spread, from 150 µg/m³ to 500 µg/m³, median 235 µg/m³; NO is confined to a narrower band of 4 µg/m³ to 11 µg/m³, median 9 µg/m³; and SO₂ varies only between 2 µg/m³ and 3 µg/m³, median 2.5 µg/m³. The number of rows per pollutant is not uniform: CO appears in four rows, NO in three, while the other four pollutants each have five rows, highlighting uneven coverage across the measurement set.

Because a substantial portion of the data is older than thirty days and some pollutants have fewer recent observations, the picture presented may not capture short‑term fluctuations at every location in the city. Users should keep in mind that conditions can differ by neighbourhood and time, and the available figures reflect the specific moments when the sensors reported.
