Air quality today
The air quality in Český Těšín is classified as Good today. The primary pollutant measured is PM2.5, with a reference value of 4.4 µg/m³, while the corresponding PM10 reference value stands at 8.7 µg/m³. Four valid measurements were recorded and are displayed via OpenAQ.
This assessment reflects the current monitoring data without speculation on causes or future conditions. 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 Český Těšín includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All data come from a single monitoring station, so the dataset represents one location rather than city‑wide coverage.
The most recent observations were taken on 2026‑02‑10, with NO₂, PM₁₀, PM₂.₅ and SO₂ each updated at 12:00 or 14:00 UTC that day. The only older entry is the NO measurement, last refreshed on 2024‑03‑11 at 10:00 UTC, which means that for this pollutant the available value is nearly two years out of date while the others reflect conditions from just a few days ago.
Because each pollutant has a single recorded value, the statistical spread is zero – the minimum, median and maximum are identical. NO registers 5.0 µg/m³, NO₂ 15.3 µg/m³, PM₁₀ 8.7 µg/m³, PM₂.5 4.4 µg/m³ and SO₂ 3.7 µg/m³. This uniformity shows that the dataset does not capture variability over time or across different parts of the city; it provides a snapshot rather than a range of conditions. Consequently, while the recent timestamps for most pollutants suggest up‑to‑date information, the limited station count and the outdated NO reading highlight that the picture of air quality in Český Těšín is based on sparse, point‑specific data and may not reflect broader spatial or temporal fluctuations.

Data notes
The data shown are based on four valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 14:00 UTC; the dataset is considered “Updated within 3 days.” This snapshot reflects conditions measured at specific monitoring points and times, so air quality can differ across neighborhoods and moments throughout Český Těšín.
