Air quality today

The air quality in České Budějovice is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 8.0 µg/m³ and a PM10 value of 8.0 µg/m³, based on five valid observations reported through OpenAQ.

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

What the data includes

The dataset for České Budějovice contains six pollutant measurements taken at a single monitoring location. All six common air‑quality species are represented: nitrogen monoxide (NO) at 2.0 µg/m³, nitrogen dioxide (NO₂) at 5.9 µg/m³, ozone (O₃) at 39.3 µg/m³, particulate matter ≤10 µm (PM10) at 8.0 µg/m³, particulate matter ≤2.5 µg/m³ (PM₂.5) also at 8.0 µg/m³, and sulphur dioxide (SO₂) at 1.3 µg/m³. The most recent update across the dataset is from 2026‑02‑10 14:00 UTC for five of the pollutants, while the NO reading dates back to 2024‑03‑11 09:00 UTC, making it the oldest entry.

Because there is only one reporting row, the range of values for each pollutant is effectively a single point – the minimum, median and maximum are identical. This means the data give a snapshot rather than a distribution, with no observed variability within the city at this time. The freshness of the data is mixed: five pollutants have been refreshed within the last three days, indicating near‑real‑time coverage, whereas the NO measurement is over two years old and flagged as “old data”.

Overall, the dataset provides complete pollutant coverage but limited spatial depth, relying on a single station’s readings. Users should keep in mind that air quality can differ across neighborhoods and times of day, and the current snapshot may not capture those variations.
