Air quality today

The air quality in Buckinghamshire today falls into the Moderate category. The primary pollutant identified is PM2.5, which consists of fine particulate matter.

Measurements recorded by OpenAQ show a PM2.5 concentration of 15.34 µg/m³ based on five valid observations. No PM10 reference value is 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 Buckinghamshire dataset currently draws from a single monitoring site – Cublington UK – and contains six rows of observations, one for each pollutant measured. The pollutants available are PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. For most of these, the latest reading was recorded on 2026‑02‑10 at 21:00 UTC, showing a very recent snapshot of conditions. The exception is PM10, whose most recent value dates back to 2025‑01‑13 at 23:00 UTC, indicating that this particular measurement is older than a year.

All six pollutants have a single reported value, so the minimum, median and maximum are identical for each. PM1 registers at 8.111 µg/m³, PM2.5 at 15.345 µg/m³ and PM10 at 29.973 µg/m³. Relative humidity is measured at 72.44 % and temperature at 11.41 °C. The particle concentration UM003 stands at 1 506.025 particles per cubic centimetre. Because each metric has only one data point, there is no spread or percentile range to describe; the dataset therefore reflects a snapshot rather than a distribution of values over time.

Overall, the coverage is limited: only one station contributes all six rows, and while most variables are up‑to‑date, the age of the PM10 reading highlights uneven freshness across pollutants. Users should keep in mind that conditions can differ across Buckinghamshire and that this single‑site snapshot may not capture spatial variations or longer‑term trends.

Data notes

The dataset for Buckinghamshire includes five valid measurements and is refreshed regularly, having been updated within three days (last update 2026‑02‑10T21:00:00+00:00). This snapshot reflects conditions at the time of collection; however, air quality can vary across different locations and times within the city, so values may not represent every neighbourhood or moment.
