Air quality today
The air quality in Mont‑Blanc today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). Two valid measurements were recorded, and the reported concentration of PM2.5 is 5.0 µg/m³, which aligns with the reference value used for this assessment.
Data are shown via OpenAQ and reflect the current monitoring results for the city. No additional pollutants reached a level that would affect the overall category. 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 air‑quality data for Mont‑Blanc includes measurements of ozone (O₃) and fine particulate matter (PM₂.5). All available observations come from a single monitoring site in Saint‑Faustin‑Lac‑Ca, giving a total of two rows of data – one row per pollutant. Both records were last updated on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window, so the information is current.
For ozone, the only reported value is 0.038 ppm, and this figure also represents the minimum, median, maximum, 10th percentile and 90th percentile across the dataset because there is just one measurement. The PM₂.5 reading shows a concentration of 5.0 µg/m³, again identical for all statistical summaries due to the single data point. Because each pollutant has exactly one observation, there is no spread or variability to describe; the dataset essentially provides a snapshot rather than a range.
With only one station contributing data, coverage across Mont‑Blanc is limited to that location, and the overall dataset consists of just two rows. While the timestamps are recent, the lack of multiple monitoring sites means the figures may not reflect conditions elsewhere in the city or surrounding areas. Users should keep in mind that air quality can differ by neighbourhood and time, and the current data set offers only a very narrow view of Mont‑Blanc’s atmospheric state.
