Air quality today
The air quality in Dorset today falls within the Good category according to the latest assessment. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 3.5555 µg/m³ based on five valid observations.
No other pollutants reached reporting thresholds, and the data are presented through OpenAQ. 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 Dorset air‑quality record is built from a single monitoring location in Swanage, giving one row of data for each measured variable. The dataset therefore contains six pollutant or environmental readings: PM1 at 1.6138 µg/m³, PM10 at 17.7750 µg/m³, PM2.5 at 3.5555 µg/m³, relative humidity at 76.15 %, temperature at 12.90 °C and particle count (UM003) at 456.7 particles/cm³. Because only one station contributes, the coverage is limited to a single point rather than city‑wide averages.
Freshness varies across the variables. The most recent measurements for PM1, PM2.5, relative humidity, temperature and UM003 were all taken on 2026‑02‑10 at 21:00 UTC, indicating that these five parameters are up‑to‑date within the last week. In contrast, the latest PM10 value dates back to 2025‑01‑13 at 23:00 UTC, making it more than a year old and the only “old” entry in the set. All six readings share identical minimum, median and maximum values because each pollutant is represented by a single observation.
Because the data come from one site, there is no spread to describe; each metric has a single reported figure rather than a range across multiple locations. The presence of both fine (PM2.5) and coarse (PM10) particulate measurements alongside humidity, temperature and particle concentration provides a basic snapshot of current atmospheric conditions at Swanage, but it does not capture spatial variation across the wider Dorset area or recent changes for PM10. Users should keep in mind that local conditions can differ elsewhere in the city and that the older PM10 reading may not reflect today’s situation.

Data notes
The dataset for Dorset includes five valid measurements and is refreshed regularly, having been updated within the past three 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 local variations may not be captured in this summary.
