Air quality today
The air quality in Montluçon today is classified as Good. The primary pollutant measured is PM2.5, fine particulate matter, with a reported concentration of 1.9 µg/m³. In addition, the monitoring data show a PM10 level of 3.0 µg/m³ based on four valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 Montluçon air‑quality record contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). All data come from a single monitoring station, so the dataset comprises one row per pollutant. The most recent observation for NO dates back to 2024‑03‑11 09:00 UTC, while the other four compounds were last updated on 2026‑02‑10 15:00 UTC, showing that the majority of the data are very fresh (within three days) but the NO reading is older by almost two years.
Across the five pollutants the reported values are identical to their minimum, median and maximum figures, indicating no observed variation in this limited sample. NO registers a constant 4.1 µg/m³, NO2 stays at 33.0 µg/m³, O3 at 19.9 µg/m³, PM10 at 3.0 µg/m³ and PM2.5 at 1.9 µg/m³. Because each pollutant has a single recorded value, the spread (p10‑p90) is zero for every metric, so no range can be described beyond the single point measurement.
The dataset therefore provides a snapshot rather than a time series: one recent entry for four pollutants and an older entry for NO. With only one monitoring location, spatial coverage across Montluçon is limited, meaning conditions may differ in other parts of the city or at times not captured by these timestamps.

Data notes
The data shown for Montluçon are based on four valid measurements and were updated within three days, with the latest refresh recorded at 2026‑02‑10 15:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
