Air quality today

The air quality in Mannheim today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 9.0 µg/m³ and a PM10 reference value of 15.6 µg/m³, based on 13 valid observations collected via OpenAQ.

Overall conditions meet the Good category criteria according to the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Mannheim’s OpenAQ feed contains data for ten measured substances: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter of 1 µm, 2.5 µm and 10 µm diameter (PM1, PM2.5, PM10), relative humidity, sulfur dioxide (SO2), temperature and a miscellaneous parameter labelled UM003. The dataset is built from three monitoring stations, giving a total of three rows of observations.

The most recent measurements are all from early February 2026, with the newest timestamp recorded at 2026‑02‑10 17:00 UTC for CO, NO2, PM2.5, PM10, O3 and SO2, while PM1 was last updated on 2026‑02‑05 21:00 UTC. The only older entry is NO, which dates back to 2024‑03‑11 11:00 UTC, indicating that nitrogen oxide data are less current than the other pollutants.

Across the available parameters the observed values show a modest spread. PM2.5 ranges from a minimum of 7.0 µg/m³ to a maximum of about 31.1 µg/m³, with a median near 9.0 µg/m³; NO varies between 2.5 and 15.3 µg/m³ (median ≈ 8.9 µg/m³); NO2 spans 25.0–44.4 µg/m³ (median ≈ 34.7 µg/m³). Particulate matter of larger size is tighter: PM10 runs from 9.7 to 15.6 µg/m³ (median ≈ 12.65 µg/m³), while PM1 is a single reported value of roughly 14.46 µg/m³. Ozone and sulfur dioxide each have only one recorded figure, 38.525 µg/m³ for O3 and 9.2 µg/m³ for SO2, both from the same February‑2026 reading. CO is also represented by a single value of 400 µg/m³ at the Friedrichsring site.

Overall the dataset provides recent coverage for most pollutants but is uneven: three substances (O3, SO2, CO) have only one observation each, and NO’s data are considerably older than the rest. Because the city’s air quality can differ between neighborhoods and over time, these snapshots give a limited picture of current conditions.

Data notes

The dataset for Mannheim includes 13 valid measurements and is Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 17:00 UTC. These figures represent a snapshot of ambient conditions captured by the monitoring network; air quality can differ across neighborhoods and change throughout the day, so the displayed values may not reflect conditions at every location or moment in the city.
