Air quality today

The air quality in the City of Edinburgh is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 30.25 µg/m³. For comparison, the reference value for PM10 on this assessment is 11.0 µg/m³.

A total of eleven valid measurements were used to generate this assessment, and the data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Edinburgh air‑quality dataset currently includes eight measured variables – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM₁, PM₂·₅ and PM₁₀), sulphur dioxide (SO₂), relative humidity and temperature (the latter is not listed in the example rows but is part of the standard OpenAQ feed). The data come from 12 individual rows collected at three monitoring stations across the city. All values are recent, with the newest timestamps recorded on 2026‑02‑10 between 19:00 and 21:00 UTC, and every pollutant is flagged as “Updated within 7 days”.

Across the eight pollutants the observed concentrations show a modest spread. CO is reported at a single value of 209.556 µg/m³, while NO₂ ranges from 8.0 to 10.901 µg/m³ with a median of about 9.45 µg/m³. O₃ and SO₂ each have one reading (44.0 µg/m³ and 1.0 µg/m³ respectively). Particulate matter displays the widest variation: PM₁ is consistently 15.167 µg/m³, PM₁₀ remains at 11.0 µg/m³, but PM₂·₅ spans from 10.0 to 30.25 µg/m³, median roughly 20.12 µg/m³ and a 90th‑percentile near 28.22 µg/m³. Relative humidity is recorded at 64.24 % for the single observation.

The dataset’s coverage is uneven – some pollutants (CO, O₃, SO₂, PM₁, PM₁₀, relative humidity) have only one recent measurement per station, whereas NO₂ and PM₂·₅ include multiple rows that allow calculation of minimum, median and maximum values. Because the data are all from a single day, they capture a snapshot rather than longer‑term trends; conditions can differ across neighbourhoods and times not represented in these rows.

Data notes

The data shown reflects eleven valid measurements and is updated within three days, with the most recent reading recorded at 2026‑02‑10T21:00:00+00:00. This snapshot provides a current view of air quality across Edinburgh, but conditions can differ by neighbourhood and time of day, so values may not represent every location or moment within the city.
