This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality today in Olešnice is classified as USG. The primary pollutant measured is PM2.5, with a reported concentration of 45.92 µg/m³ based on five valid observations from OpenAQ.
Data indicate that fine particulate matter dominates the current profile, while no PM10 value is available for this assessment. 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 Olešnice contains measurements from a single monitoring location that contributes six rows of data. All six pollutant types are represented: fine particles (PM1), coarse particles (PM10), fine‑to‑coarse mixture (PM2.5), relative humidity, temperature and particle number concentration (UM003). The most recent values for five of the pollutants were recorded on 2026-02-10 at 18:00 UTC, showing that the majority of the data is very fresh. Only the PM10 reading is older, with its last update on 2025-01-12 at 02:00 UTC, which means that information for this metric lags behind the others by more than a year.
Across the six rows each pollutant has a single reported value, so there is no observed spread within the dataset. The median and extreme values are identical for every parameter: PM1 sits at 27.40 µg/m³, PM10 at 6.72 µg/m³, PM2.5 at 45.92 µg/m³, relative humidity at 67.46 %, temperature at 6.31 °C and UM003 at 4 049.44 particles/cm³. Because only one measurement per pollutant is available, the data cannot illustrate variability over time or between locations within Olešnice.
The coverage is therefore limited: a single sensor provides a snapshot rather than a continuous trend, and the age discrepancy for PM10 highlights uneven freshness across pollutants. Users should keep in mind that conditions can differ throughout the town and at other times of day, so this dataset offers a brief, point‑in‑time picture rather than a comprehensive view of air quality in Olešnice.

Data notes
The current dataset for Olešnice includes five valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 18:00 UTC. This snapshot reflects conditions at the time of collection; air quality can vary across different neighborhoods and moments throughout the day, so values may not represent every location or instant in the city.
