Air quality today
The air quality in Schwerte today is classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 6.307 µg/m³. In addition, the PM10 level recorded is 9.087 µg/m³ based on four valid measurements.
Data are shown via OpenAQ and reflect the current assessment for the city. 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 dataset for Schwerte in North‑Rhine Westphalia contains measurements from five individual rows, each representing a single monitoring point that reports on the same set of pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10) and particulate matter ≤2.5 µm (PM2.5). All values are expressed in micrograms per cubic metre (µg/m³).
Freshness varies across the pollutants. The most recent updates for NO₂, O₃, PM10 and PM2.5 were recorded on 2026‑02‑10 at 17:00 UTC, indicating that these four compounds have data refreshed within the last three days. In contrast, the NO measurement is older, with its latest entry dated 2024‑03‑11 at 11:00 UTC, which means the nitrogen monoxide reading has not been updated for almost two years. Because only one row supplies each pollutant, there is no internal spread of values; each metric shows a single reported figure that also serves as its minimum, median and maximum.
The numbers themselves are modest and tightly clustered: NO stands at 3.69 µg/m³, NO₂ at 11.852 µg/m³, O₃ at 42.035 µg/m³, PM10 at 9.087 µg/m³ and PM2.5 at 6.307 µg/m³. With a single data point per pollutant, there is no observable variability or range to describe trends over time or across locations within the city. Consequently, while the dataset provides a snapshot of current air quality for these five substances, it does not capture spatial differences that may exist elsewhere in Schwerte, and the older NO value highlights a gap in recent coverage for that particular gas.

Data notes
The data shown for Schwerte are based on four valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10 17:00 UTC; the dataset is therefore “Updated within 3 days.” This snapshot reflects conditions at the time of sampling, but air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
