Air quality today

The air quality in Nîmes today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 reference value of 4.8 and a PM10 reference value of 6.4, based on four valid observations collected via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Nîmes 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). Data come from three monitoring stations, providing a total of thirteen recent observations across the city. Most readings are fresh: NO₂, PM₁₀, PM₂.₅, and O₃ were all last updated on 2026‑02‑10 at 15:00 UTC, which falls within the “updated within three days” category. The only older entry is for NO, recorded on 2024‑03‑11 at 09:00 UTC, so its information is considerably less current than the other pollutants.

Across the recent data the observed values show a modest spread. For NO₂ the measurements range from 13.2 to 34.9 µg/m³ with a median of 13.9 µg/m³; PM₁₀ varies between 4.6 and 16.1 µg/m³, median 6.4 µg/m³; PM₂.5 runs from 2.9 to 9.2 µg/m³, median 4.8 µg/m³; O₃ is tightly clustered between 50.8 and 53.2 µg/m³, median 52.0 µg/m³; and NO shows a narrow band from 2.9 to 3.3 µg/m³, median 3.1 µg/m³. The percent‑ile values indicate that most recent observations sit near the lower end of each pollutant’s range (10th percentile around 13.3 µg/m³ for NO₂, 5 µg/m³ for PM₁₀, 3.3 µg/m³ for PM₂.5, and 51 µg/m³ for O₃).

Because the dataset contains only three stations, spatial coverage is limited; conditions can differ across neighborhoods that are not directly represented by these points. Additionally, the older NO measurement means that recent nitrogen monoxide levels are not captured with the same timeliness as the other pollutants, so any interpretation should consider this gap in freshness.

Data notes

The dataset for Nîmes includes four 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 points; air quality can differ across neighborhoods and change throughout the day, so this information reflects only the recorded moments and locations.
