Air quality today

The air quality in Strasbourg today is classified as Good. The primary pollutant measured is PM2.5, with fine particle concentrations recorded at 2.1 µg/m³.

Measurements from ten monitoring stations show a PM10 level of 4.8 µg/m³ alongside the PM2.5 value. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Strasbourg includes measurements of 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 20 individual rows of data collected from six monitoring stations, giving a modest spatial coverage that captures conditions at several key locations such as Strasbourg Nord and the Neudorf Ecoquartier Danube.

Most of the pollutant readings were updated very recently – the latest timestamps for NO₂, PM₁₀, PM₂.5 and O₃ are all from 2026‑02‑10 15:00 UTC, meaning those values reflect conditions measured just a few days ago. In contrast, the NO data is older, with its most recent entry dated 2024‑03‑11 08:00 UTC, so information on that gas is less current than for the other pollutants.

The observed concentrations span a fairly wide range. For NO₂ the values recorded across the rows vary from a low of 3.6 µg/m³ to a high of 29.6 µg/m³, with a median around 15.9 µg/m³; PM₁₀ ranges between 4.0 and 25.6 µg/m³, median 20.1 µg/m³; PM₂.5 is the most limited series, with only two recent rows showing values from 2.1 to 17.5 µg/m³ and a median of 9.8 µg/m³; O₃ has a single recent measurement of 58.4 µg/m³; NO, based on five older rows, varies from 2.3 to 26.7 µg/m³ with a median of 11.2 µg/m³. The distribution indicates that while some pollutants (NO₂, PM₁₀) have a relatively broad spread, others such as O₃ and PM₂.5 are represented by very few recent points, limiting the ability to describe city‑wide patterns for those components.

Overall, the dataset provides fresh information for most measured gases and particles, but the uneven number of rows per pollutant—especially the older NO data and the single O₃ entry—means that conditions can differ across neighborhoods and times, and a fuller picture would require more uniformly recent observations from all stations.

Data notes

The data shown for Strasbourg are based on ten valid measurements and have been updated within three days, with the most recent refresh recorded at 2026‑02‑10T15:00:00+00:00. This snapshot reflects conditions captured across the monitoring network at that time. Air quality can vary by location and moment within the city, so values may differ from those experienced elsewhere or later in the day.
