Air quality today
The air quality in Frýdek‑Místek is classified as Good today. The primary pollutant measured is PM2.5, with a reference value of 3.1 µg/m³, while PM10 shows a reference value of 4.6 µg/m³ based on three valid measurements reported through OpenAQ.
These figures indicate that the current concentrations are within the range associated with the Good category. 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 Frýdek‑Místek contains four pollutant measurements collected from a single monitoring location. All four common air quality indicators are represented: nitrogen monoxide (NO) at 1.1 µg/m³, nitrogen dioxide (NO₂) at 5.5 µg/m³, particulate matter up to 10 µm (PM10) at 4.6 µg/m³ and fine particulate matter (PM2.5) at 3.1 µg/m³. Because the data come from only one station, the spatial coverage across the city is limited; any variation that occurs in different neighborhoods will not be captured by these figures.
The timestamps show a mixed picture of freshness. The NO value dates back to 2024‑03‑11 10:00 UTC and is flagged as “old data,” whereas the other three pollutants were last updated on 2026‑02‑10 14:00 UTC, which falls within the “updated within 3 days” window. This means that for NO the information is more than a year old, while NO₂, PM10 and PM2.5 reflect the most recent conditions available from the source.
All four pollutants have identical minimum, median and maximum values in this snapshot, indicating no observed variability across the recorded period at this site. The lack of spread (each metric equals its 10th and 90th percentiles) suggests that only a single measurement point is currently stored rather than a time series. Consequently, while the dataset provides a quick reference for current concentrations of NO, NO₂, PM10 and PM2.5 in Frýdek‑Místek, it does not capture temporal changes or spatial differences within the city.
