Air quality today

The air quality in Herzogenbuchsee is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 14.89 µg/m³ based on five valid observations reported through OpenAQ.

These figures reflect the latest available data for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Herzogenbuchsee monitoring set consists of a single measurement row that records six different parameters: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. Because there is just one station, each pollutant is represented by a single value rather than an average across multiple sites.

All of the recent readings – PM1 (8.61 µg/m³), PM2.5 (14.89 µg/m³), relative humidity (66.31 %), temperature (10.52 °C) and UM003 (1 650.38 particles/cm³) – were last updated on 2026‑02‑10 at 22:00 UTC, showing that the newest data are less than a day old. The PM10 value is older, recorded on 2025‑01‑13 at 23:00 UTC, so it does not reflect current conditions for that specific metric.

Because only one row is available, the dataset shows no variation: each pollutant’s minimum, median and maximum are identical to the single reported figure. This means there is no spread or range to describe within Herzogenbuchsee itself; any change in air quality would have to be captured by a new measurement at this same location. The freshness of most parameters is high, but the outdated PM10 reading highlights an uneven timeliness across pollutants.

Overall, the data provide a snapshot rather than a trend, and because coverage is limited to one site, conditions elsewhere in the city may differ from what these numbers represent.

Data notes

The data shown for Herzogenbuchsee is based on five valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions at the time of sampling; air quality can differ across neighbourhoods and change throughout the day, so values may not reflect current or location‑specific conditions elsewhere in the city.
