Air quality today
The air quality in Wismar today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 30.55 and a PM10 reference value of 32.21, based on four valid observations reported through OpenAQ.
These figures reflect the current monitoring results 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 Wismar contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.5). In total ten individual rows have been recorded, coming from two monitoring stations in the city.
The most recent values are fairly up‑to‑date for four of the pollutants, with the latest timestamps on 2026-02-10 18:00 UTC for NO₂, O₃, PM₁₀ and PM₂.5. The NO data is older, last updated on 2024-03-11 11:00 UTC, which means that for this gas the information is almost two years out of date while the other compounds reflect conditions from just a few days ago.
Across the five substances the observed concentrations span modest ranges. NO varies between 0.63 and 1.68 µg/m³ with a median of about 1.16 µg/m³, indicating little fluctuation in the available records. NO₂ shows a broader spread from 11.67 to 22.77 µg/m³, centred around a median of 17.22 µg/m³. Ozone reaches up to 40.08 µg/m³ and falls as low as 23.9 µg/m³, with a median near 32 µg/m³. PM₁₀ values range from 11.9 to 32.21 µg/m³ (median ≈ 22.1) and PM₂.5 from 8.18 to 30.55 µg/m³ (median ≈ 19.4). The 10th‑percentile figures are close to the minima for each pollutant, while the 90th‑percentile values sit near the upper ends, suggesting that most recorded points cluster toward the extremes of their respective ranges.
Because only two stations contribute data, spatial coverage is limited; conditions can differ across neighborhoods and times not captured by these rows. The dataset therefore provides a snapshot rather than a comprehensive picture of air quality throughout Wismar.

Data notes
The data shown for Wismar are based on four valid measurements and have been updated within 3 days, with the latest refresh recorded at 2026‑02‑10 18:00 UTC. These figures represent a brief snapshot of conditions; air quality can differ across neighbourhoods and change throughout the day, so values may not reflect current or localized levels elsewhere in the city.
