Air quality today

The air quality in Milton Keynes today is classified as Moderate. The primary pollutant measured is PM2.5. The observed PM2.5 concentration is 12.41 µg/m³, matching the reference value of 12.41 µg/m³. Ten valid measurements contributed to this assessment. PM10 data is not available for this period.

Data is shown via OpenAQ. The reported values are based on ten recent observations. These observations are part of the OpenAQ dataset for the city. No PM10 measurement is included in the current dataset. PM2.5 concentrations are expressed in micrograms per cubic metre. Values are rounded to two decimal places for reporting. The assessment uses ten valid measurements. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Milton Keynes air‑quality record currently draws on two monitoring stations, each contributing a row of recent measurements for five pollutants. All of the latest values were recorded at the same moment – 2026‑02‑10 21:00 UTC – and the dataset is flagged as having been updated within the past 30 days, so the information reflects the city’s conditions at a very recent point in time.

For PM1 the observations span from roughly 7.9 to 13.2 µg/m³, with a median of 10.55 µg/m³ and the middle 80 % of readings falling between 8.45 and 12.65 µg/m³. PM2.5 shows a broader spread, ranging from about 12.4 to 31.2 µg/m³; the median sits at 21.78 µg/m³ and the 10th‑90th percentile band stretches from 14.29 to 29.28 µg/m³, indicating more variability across the two sites. Relative humidity values are clustered between 65.3 % and 71.7 %, with a median of 68.5 % and a tight 10th‑90th range of 65.96 to 71.08 %. Temperature measurements are similarly narrow, ranging from 8.68 °C to 11.86 °C, a median of 10.27 °C and an 80 % spread from 8.99 to 11.54 °C. The particle count (UM003) varies from 755 to 1 420 particles per cm³, with a median of 1 088 and the central 80 % of values between 822 and 1 353 particles/cm³.

Because the dataset is limited to two stations, the figures capture conditions at those specific locations but may not represent the full spatial diversity of Milton Keynes. Nonetheless, the recent timestamp and the detailed percentile information give a clear snapshot of the current air‑quality profile for the pollutants that are being monitored.
