Air quality today

The air quality in Bons‑en‑Chablais today falls into the Good category according to OpenAQ data. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 2.91 µg/m³ based on five valid observations.

What the data includes

The Bons‑en‑Chablais monitoring set currently provides five recent observations from a single measurement site. All of the recorded pollutants – PM1, PM2.5, relative humidity, temperature and UM003 (particle count) – were last updated on 2026‑02‑10 at 18:00 UTC, which falls within the three‑day freshness window used for the data feed.

For each pollutant the dataset contains a single value that also serves as its minimum, median and maximum because only one row is available. PM1 registers at 0.972 µg/m³, while fine particulate matter (PM2.5) measures 2.914 µg/m³. The relative humidity reading stands at 56.59 % and the ambient temperature is 11.84 °C. Particle concentration captured by the UM003 sensor is 185.52 particles per cm³. Because there is no spread of values, statistical descriptors such as inter‑percentile ranges cannot be calculated; the data therefore represent a snapshot rather than a distribution.

With only one monitoring station contributing five rows, coverage across the city is limited and does not capture spatial variation. The timestamps are uniformly recent, but the lack of multiple sites means that conditions in other neighbourhoods may differ from those recorded at this single point. Users should keep in mind that while the figures are up‑to‑date, they reflect a narrow sampling window and do not convey longer‑term trends or variability across Bons‑en‑Chablais.
