Air quality today

The air quality in Paris today falls into the USG category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 39.11 µg/m³ and a PM10 reference value of 13.4 µg/m³, based on 34 valid observations.

These figures reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Paris pulls measurements from 62 recorded rows across 17 monitoring sites, covering a suite of pollutants and weather variables that are routinely reported by OpenAQ sensors. Available concentrations include nitrogen dioxide (NO₂), nitric oxide (NO), ozone (O₃), carbon monoxide (CO), particulate matter in three size fractions (PM₁, PM₂.5, PM₁₀), as well as relative humidity and temperature, although the latter is not listed among the most recent values.

Freshness varies by pollutant. The newest readings for NO₂, PM₁₀, PM₂.5, O₃, CO, PM₁ and relative humidity were all taken on 2026‑02‑10 between 15:00 and 18:00 UTC, giving a snapshot that is only a few days old. In contrast, the latest NO measurement dates back to 2024‑03‑11, making it considerably older than the other parameters.

Across the recent data, concentrations show a broad spread. NO₂ values range from 9.3 to 57.8 µg/m³ with a median of 23.2 µg/m³; O₃ spans 23.0 to 78.0 µg/m³ (median 59.7 µg/m³); CO varies between 166 and 531 µg/m³ (median 198 µg/m³). Particulate matter is generally lower, with PM₂.5 from 6.0 up to about 39.1 µg/m³ (median 10.2 µg/m³) and PM₁₀ from 4.7 to 23.65 µg/m³ (median 14.3 µg/m³). Relative humidity is recorded as a single value of 67.20 % at Pont de Grenelle.

The coverage is uneven: while most pollutants have recent observations from multiple sites, NO data relies on an older entry and temperature is not represented among the freshest rows. Consequently, the snapshot reflects current conditions in some locations but may miss recent changes elsewhere in the city.

Data notes

The dataset for Paris includes 34 valid measurements and is updated within 3 days, with the most recent data recorded at 2026‑02‑10T18:00:00+00:00. This snapshot reflects conditions measured across the monitoring network at that time; air quality can vary by location and moment within the city, so values may differ from what you experience elsewhere or later in the day.
