This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in La Rochelle today is classified as Good. The primary pollutant measured is PM2.5 (fine particles). According to the latest data shown via OpenAQ, the concentration of PM2.5 is 8.6 µg/m³ and the accompanying PM10 level is 12.8 µg/m³, based on four valid measurements.
These values reflect the current monitoring snapshot for the city. 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 La Rochelle air‑quality feed includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter up to 10 µm (PM₁₀) and fine particulate matter up to 2.5 µm (PM₂.₅). Data come from two monitoring stations that together provide ten recent rows of observations.
The most recent values are fairly fresh for the gases, with NO₂ and O₃ both updated on 2026‑02‑10 at 15:00 UTC, while NO was last recorded on 2024‑03‑11 at 09:00 UTC. The particulate measurements are a day older, with PM₁₀ and PM₂.5 refreshed on 2026‑02‑09 at 03:00 UTC. Across the dataset the minimum–maximum spans show that NO varies between 3.1 and 5.7 µg/m³ (median 4.4), NO₂ ranges from 7.9 to 21.5 µg/m³ (median 14.7), O₃ runs from 36.3 up to 51.4 µg/m³ (median about 43.9), PM₁₀ stays narrow between 11.6 and 12.8 µg/m³ (median 12.2) and PM₂.5 covers 3.4 to 8.6 µg/m³ (median 6.0). The percentile data indicate that most NO readings sit near the lower end of their range, while O₃ values are clustered toward the higher end.
Because only two stations contribute, the spatial coverage is limited; conditions can differ across neighbourhoods and times not captured by these rows. Moreover, a portion of the dataset (the NO record) is older than three months, so recent trends for that pollutant are less certain compared with the more up‑to‑date gas and particulate readings.
