Mr. Duck’s Air Quality Score
Unhealthy for sensitive groups for Darlington, England, United Kingdom
This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Darlington today falls within the USG category. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 39.45 µg/m³ based on five valid observations recorded via OpenAQ.
Overall, the data indicate that fine particulate matter is the dominant factor influencing air quality at this time. 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 Darlington data set contains five recorded rows drawn from a single monitoring station, covering five key variables: PM1, PM2.5, relative humidity, temperature and the particle count UM003. All of the measurements were last updated on 2026‑02‑09 21:00 UTC, which falls within the “updated within 7 days” freshness window, so the snapshot is recent but represents only one point in time rather than a continuous stream.
For each pollutant the dataset provides a single value that also serves as the minimum, median and maximum. PM1 registers at 21.93900000254313 µg/m³, while PM2.5 is measured at 39.447333272298174 µg/m³. Relative humidity stands at 67.5889996846517 %, temperature at 10.437166643142701 °C and the UM003 particle concentration at 3478.0249999999996 particles/cm³. Because there is only one reading per parameter, there is no observable spread or percentile range; the reported figures are both the typical (median) and extreme values for this snapshot.
The limited coverage—one station supplying a single recent record for each pollutant—means that spatial and temporal variations across Darlington cannot be captured in this data set. While the information is up‑to‑date, it reflects conditions at only one location and moment, so broader city‑wide air quality patterns may differ from what is shown here.

Data notes
The data shown for Darlington is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑09T21:00:00+00:00 (updated within 3 days). This snapshot provides a current view of ambient air quality, but conditions can differ across neighbourhoods and change throughout the day, so local variations may not be fully captured in these figures.
