Air quality today
The air quality in Biarritz today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 2.3 µg/m³, while the accompanying PM10 level stands at 7.9 µg/m³ based on four valid observations.
Data are shown via OpenAQ and reflect the current monitoring results 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 air‑quality dataset for Biarritz 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 values come from a single monitoring location, the Biarritz‑hippodrome station, so the dataset comprises five rows in total.
The most recent observations are fairly current for three of the pollutants. NO₂ and O₃ were last updated on 2026‑02‑10 at 15:00 UTC, while PM₁₀ and PM₂.5 were refreshed on 2026‑02‑09 at 03:00 UTC. The NO measurement is older, with its latest timestamp from 2024‑03‑11 at 09:00 UTC, indicating that the dataset includes one record that is more than a year out of date. Overall, the freshest timestamps sit within the last few days, but coverage is uneven because only the nitrogen monoxide reading lags behind.
All five pollutants show identical minimum, median and maximum values, meaning each measurement set consists of a single reported figure. NO registers 1.2 µg/m³, NO₂ 5.5 µg/m³, O₃ 55.1 µg/m³, PM₁₀ 7.9 µg/m³ and PM₂.5 2.3 µg/m³ at the hippodrome site. Because there is no spread in the data, the reported values represent point estimates rather than a range of observations over time. Consequently, while the dataset provides up‑to‑date snapshots for most pollutants, it does not capture variability across different parts of Biarritz or over longer periods, and users should keep in mind that conditions can differ by location and moment.
