Air quality today

The air quality in Poitiers today is classified as Good. The primary pollutant measured is PM2.5, with a reference value of 1.3 µg/m³, while the corresponding PM10 reference stands at 2.4 µg/m³. Ten valid measurements were recorded to support this assessment.

Data is shown via OpenAQ and reflects the current conditions for Poitiers in Nouvelle‑Aquitaine, France. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Poitiers air‑quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from 28 individual rows collected at five monitoring stations across the city, giving a modest spatial picture of current conditions.

Most pollutant readings are recent: CO, NO₂, O₃, PM10 and PM2.5 were all last updated on 2026‑02‑10 at 15:00 UTC, which falls within the “updated within three days” category. Their values span a wide range – for example, CO varies from 198 µg/m³ up to 493 µg/m³ with a median of 345.5 µg/m³, while NO₂ ranges between 3.7 and 66.1 µg/m³ (median 21.6 µg/m³). Ozone shows a minimum of 7.5 µg/m³ and a maximum of 49 µg/m³, with the typical reading around 31 µg/m³. Particulate matter is generally low, with PM10 between 2.4 and 33.7 µg/m³ (median 15.5 µg/m³) and PM2.5 from 1.3 to 10.3 µg/m³ (median 5.8 µg/m³). The 10th‑percentile values are close to the minima for each pollutant, indicating that low concentrations are common, while the 90th‑percentile values approach the upper ends of the observed ranges.

Nitrogen oxide is an outlier in terms of data freshness: its most recent entry dates from 2024‑03‑11 at 09:00 UTC and is flagged as “old”. This single older record (34.2 µg/m³ at Poitiers‑Le Nain) means that NO coverage is less current than the other pollutants, and overall the dataset contains eight rows updated within three days but two rows that are older than seven days. Consequently, while the recent measurements give a clear snapshot for most species, conditions for NO may be less reliably represented, and variations across neighborhoods or times of day could differ from what the limited station network captures.

Data notes

The dataset for Poitiers includes ten valid measurements and is updated within three days, with the most recent values recorded on 2026‑02‑10 at 15:00 UTC. These figures represent a snapshot of ambient conditions across the city; actual air quality can differ by specific location and time of day, so users should consider local variations when interpreting the data.
