Air quality today

The air quality in Toulouse today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 6.6 and a PM10 reference value of 15.3, based on sixteen valid observations recorded via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the latest assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Toulouse includes measurements of nitrogen dioxide, particulate matter 10 µm and smaller, fine particulate matter 2.5 µm, nitric oxide, ozone and sulfur dioxide. In total there are 37 data rows drawn from six monitoring stations across the city. For most pollutants the latest values were recorded on 2026‑02‑10 at 15:00 UTC, so the information is fresh – within the past three days – for nitrogen dioxide, PM10, PM2.5 and ozone. Nitric oxide is only represented by older data from 2024‑03‑11 09:00 UTC, while sulfur dioxide comes from a single measurement taken on 2018‑07‑06 19:00 UTC.

Across the recent records the observed concentrations span a wide range. Nitrogen dioxide varies from a low of 4.2 µg/m³ to a high of 83.5 µg/m³, with a median around 33 µg/m³; the example reading is 44.3 µg/m³ at the Rte Albi site. PM10 values are between 4.5 and 28.6 µg/m³, median roughly 9 µg/m³, exemplified by an 8.1 µg/m³ measurement at Mazades. Fine particles (PM2.5) range from 2.4 to 9.0 µg/m³, median about 5.9 µg/m³, with a typical reading of 5.3 µg/m³ also at Mazades. Ozone shows values from 3.3 up to 60.4 µg/m³, median 35 µg/m³, illustrated by a 35.0 µg/m³ figure at the école m. Jacquier site. Nitric oxide displays a much broader spread, from 1.2 to 291.8 µg/m³, median 8.2 µg/m³, with an example of 33.2 µg/m³ at Port de l’Embouchure. Sulfur dioxide is constant at 0.85 µg/m³ in the single available record.

Because the coverage differs markedly between pollutants – recent data for four compounds but older or singular entries for nitric oxide and sulfur dioxide – the picture of air quality can vary by location and time. Users should keep in mind that some parts of Toulouse are monitored more frequently than others, and that conditions may change between the dates of the latest observations.

Data notes

The data shown for Toulouse reflects 16 valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T15:00:00+00:00. This snapshot provides a current view of ambient air quality across the city, but conditions can differ by neighbourhood and change rapidly over short periods; therefore, the figures represent an approximate overview rather than precise real‑time levels for every location.
