Air quality today

The air quality in Alcobendas today is classified as Good. The primary pollutant identified is PM2.5, with a measured value of approximately 0.97 µg/m³. In addition, the concentration of larger particles (PM10) is recorded at about 6.0 µg/m³ based on sixteen valid observations.

These figures are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Alcobendas air‑quality feed currently provides data for eight measured variables – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM₁, PM₂.₅ and PM₁₀), relative humidity and temperature – collected from three monitoring stations that together contribute 21 individual rows of observations. The most recent updates are fairly current for most pollutants: NO₂, O₃ and PM₁₀ were last refreshed on 2026‑02‑09 at 15:00 UTC, while the finer particulate metrics (PM₁ and PM₂.5), humidity and temperature show a newer timestamp of 2026‑02‑10 at 20:00 UTC. The only older entry is NO, whose latest value dates back to 2024‑02‑28 at 23:00 UTC, indicating that this particular sensor has not reported in the past two years.

Across the recent data set, concentrations span a wide range. For NO₂ the minimum recorded value is 19 µg/m³ and the maximum reaches 65 µg/m³, with a median of 24 µg/m³; O₃ varies from 3 to 58 µg/m³ (median 52 µg/m³), while PM₁₀ ranges between 6 and 38 µg/m³ (median 8 µg/m³). The ultra‑fine particles show much lower absolute numbers, with PM₁ ranging from essentially zero to 0.615 µg/m³ (median ≈0.31 µg/m³) and PM₂.5 from 0.253 to 0.971 µg/m³ (median ≈0.61 µg/m³). Relative humidity recorded a high of 66.7 % and a low of 42.4 %, with a median near 54.5 %; temperature varied between roughly 16 °C and 24.7 °C, centering on a median of 20.3 °C.

The dataset therefore offers a fairly fresh snapshot for most pollutants, but the uneven recency – especially the dated NO reading – means that short‑term fluctuations in nitrogen monoxide are not captured as reliably as those for other species. With only three stations feeding the system, spatial variation within Alcobendas may be underrepresented; conditions can differ across neighborhoods and times of day, so the figures presented reflect an average view rather than a complete citywide picture.

Data notes

The data shown for Alcobendas reflects 16 valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T20:00:00+00:00. This snapshot provides a recent overview of ambient air quality, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
