Air quality today

The air quality in West Dunbartonshire today falls into the Moderate category. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 15.84 µg/m³ based on sixteen valid observations recorded by OpenAQ.

No other pollutants reached reporting thresholds, and PM10 data are not available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for West Dunbartonshire currently provides data on seven measured pollutants: NO₂, PM₁, PM₂·₅, PM₁₀, relative humidity, temperature and UM003 (particle concentration). These values come from a total of six sensor rows across the council area. Freshness varies markedly between pollutants: the most recent readings for PM₁, PM₂·₅, relative humidity, temperature and UM003 were all recorded on 2026‑02‑10 at 21:00 UTC, while NO₂ was last updated a hour earlier on the same day (2026‑02‑10 20:00 UTC). The only PM₁₀ observation is older, dated 2024‑12‑18 14:00 UTC, and therefore represents historic rather than current conditions.

Across the five recently refreshed pollutants the data show a broad range of values. PM₁ spans from just under half a microgram per cubic metre (0.49 µg/m³) to almost thirty µg/m³, with a median of 5.82 µg/m³ at Kilbowie Rd, Clydebank. PM₂·₅ varies between roughly 2.8 and 43.7 µg/m³, centring on a median of 15.84 µg/m³ at the same site. Relative humidity recorded a high of 71.18 % and a low of 38.98 %, with a typical value near 67.93 %. Temperature ranged from about 8.4 °C to 20.5 °C, medianing around 10.39 °C. UM003 particle counts were between 289 and 2 096 particles per cm³, with a median of 600.96 at Kilbowie Rd.

The dataset is uneven: five pollutants have up‑to‑date measurements from the same location, but NO₂ is only represented by a single roadside sensor in Dumbarton, and PM₁₀ relies on a lone, older reading from a roundabout in Clydebank. Consequently, while recent data give a snapshot of air quality at specific points, conditions elsewhere in West Dunbartonshire may differ and the overall picture is limited by the sparse spatial coverage and the dated PM₁₀ value.

Data notes

The dataset for West Dunbartonshire includes 16 valid measurements and is refreshed regularly, having been updated within 3 days (last update: 2026‑02‑10T21:00:00+00:00). These figures represent a snapshot of current conditions; air quality can differ across neighbourhoods and change throughout the day, so values shown may not reflect every location or moment within the city.
