Air quality today
The air quality in Szombathely is classified as Good today. The main pollutant identified is PM10, with a measured reference value of 33.0 micrograms per cubic metre based on three valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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 Szombathely data set contains five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂) – drawn from a single monitoring station that contributes five rows of observations. Freshness varies across the suite: the most recent updates for NO₂, O₃, PM₁₀ and SO₂ are all dated 2026‑02‑10 20:00 UTC, while CO and SO₂ rely on older readings from 2024‑08‑11 07:00 UTC. This mix means that four of the five pollutants reflect conditions within the last three days, but carbon monoxide data is more than a year old.
Across the available measurements the values are remarkably uniform because each pollutant has only one recorded figure. CO registers at 475.0 µg/m³, NO₂ at 14.2 µg/m³, O₃ at 26.6 µg/m³, PM₁₀ at 33.0 µg/m³ and SO₂ at 4.9 µg/m³. For every pollutant the minimum, median and maximum are identical, indicating no observed spread in this snapshot. Consequently, there is no internal range to describe variability; the data simply reflects a single point in time for each substance.
Because the dataset stems from just one station, spatial coverage across Szombathely is limited. Conditions can differ in other neighborhoods or at different times of day, and the older CO reading underscores that not all pollutants are captured with equal timeliness. Users should keep in mind that these figures represent a narrow slice of the city’s air quality rather than a comprehensive, continuously updated picture.

Data notes
The data shown for Szombathely is based on three valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 20:00 UTC. These values represent a snapshot of conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
