Air quality today

The air quality in Bordeaux today is classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter that is measured alongside PM10. According to the latest data shown via OpenAQ, the reference value for PM2.5 stands at 10.0 µg/m³ and for PM10 at 11.7 µg/m³. Six valid measurements were recorded to determine these values.

These figures reflect the current assessment without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data for Bordeaux includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Across the city there are 15 individual rows of observations coming from four monitoring stations, so each pollutant is not necessarily represented at every site.

The most recent values were recorded on 2026-02-10 15:00 UTC for NO2 and O3, on 2026-02-09 03:00 UTC for PM10 and PM2.5, while the last NO reading dates back to 2024-03-11 09:00 UTC. This means that three of the five pollutants have updates within the past three days, but NO data is older by almost two years. Median concentrations show a modest spread: NO ranges from 1.5 to 64.5 µg/m³ with a median of 4.55 µg/m³; NO2 varies between 4.3 and 23.8 µg/m³ (median ≈ 14.9 µg/m³); O3 sits between 26.9 and 51.5 µg/m³ (median ≈ 39.2 µg/m³). PM10 values are tightly clustered, from 9.5 to 17.3 µg/m³ with a median of 11.25 µg/m³, and PM2.5 is reported as a single constant value of 10.0 µg/m³ at its station.

Because the observation rows are unevenly distributed – only two stations provide O3 data while all four contribute to NO2 and PM measurements – spatial coverage differs by pollutant. The overall picture combines very recent readings for most pollutants with one older series, indicating that conditions can change across locations and times, and the available snapshot reflects the specific moments when each sensor last reported.

Data notes

The dataset for Bordeaux includes six valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T15:00:00+00:00). These values represent a snapshot of ambient conditions at specific monitoring sites; air quality can differ across neighborhoods and change throughout the day, so this information reflects only the time and locations measured.
