Air quality today
The air quality in Celestynów today is classified as Unhealthy. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 74.48 µg/m³ based on five valid observations reported through OpenAQ. This level reflects the current assessment for the city.

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 Celestynów monitoring set consists of six data rows that together provide readings for six pollutants: PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particle count per cubic centimetre). All values are single‑point measurements – the minimum, median and maximum reported for each pollutant are identical because only one recent observation is available for most of them. The freshest timestamps were recorded on 2026-02-10 at 20:00 UTC for PM1, PM2.5, relative humidity, temperature and UM003, showing that these five parameters have been updated within the last week. In contrast, the PM10 reading dates back to 2025-01-13 at 23:00 UTC, indicating that this particular pollutant has not been refreshed for over a year.
The numeric snapshot shows PM1 at 41.67 µg/m³, PM2.5 at 74.48 µg/m³ and PM10 at 188.46 µg/m³, while relative humidity stands at 59.59 % and temperature at 5.17 °C. The particle counter (UM003) reports 7 579.86 particles per cm³. Because each pollutant is represented by a single value, there is no observed spread or variability within the dataset; the reported figures are both the minimum and maximum for their respective parameters.
Overall, the data coverage in Celestynów is limited to one sensor location, and while most measurements are recent, the outdated PM10 entry highlights an uneven refresh rate across pollutants. Users should keep in mind that conditions can differ throughout the city and over time, and the current snapshot reflects only the moment captured by this solitary monitoring point.
