This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Weil am Rhein is classified as Good today. The main pollutant identified is PM2.5, fine particulate matter, and the reference concentration for this pollutant is 4.0 µg/m³. Measurements also include a PM10 reference value of 5.7 µg/m³, based on four valid observations collected through OpenAQ.
Overall conditions meet the Good category criteria according to the available data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality record for Weil am Rhein currently contains five pollutant measurements – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All of these come from a single monitoring station, so the dataset consists of five rows in total.
The most recent data points were uploaded within the last three days for four of the pollutants: NO₂ at 18.342 µg/m³, O₃ at 39.004 µg/m³, PM₁₀ at 5.7 µg/m³ and PM₂.₅ at 4.0 µg/m³, each recorded on 2026‑02‑10 20:00 UTC. The NO value is older, last updated on 2024‑03‑11 11:00 UTC, and therefore does not reflect the current conditions as closely as the other parameters.
Because each pollutant has only a single reported figure, the minimum, median and maximum values are identical for every substance. This means there is no observed spread in the data – NO sits at 2.8 µg/m³, NO₂ at 18.342 µg/m³, O₃ at 39.004 µg/m³, PM₁₀ at 5.7 µg/m³ and PM₂.₅ at 4.0 µg/m³. The uniformity of these numbers indicates that the dataset provides a snapshot rather than a range of variability over time or across locations within the city.
Overall, the coverage is limited to one measurement site, with four pollutants offering very recent readings while the NO figure remains dated. Consequently, while the available values give an immediate picture of the current air quality at that specific point, they do not capture spatial differences or short‑term fluctuations that may occur elsewhere in Weil am Rhein.

Data notes
The data shown for Weil am Rhein is based on four valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T20:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent current or city‑wide conditions.
