Air quality today

The air quality in Graz, Styria, Austria is classified as USG today. The primary pollutant identified is PM2.5. The monitoring network recorded 22 valid observations for the pollutants during the reporting interval. This assessment reflects the current measurement set without reference to historical data.

The reported concentration for PM2.5 is 48.80 µg/m³, and the concentration for PM10 is 32.04 µg/m³. Both fine and coarse particle levels are presented as measured values. The values are expressed in micrograms per cubic meter, which is the standard unit for particulate matter reporting. No additional pollutant data are included in this summary. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Graz pulls information from 14 monitoring stations and contains 53 individual rows of measurements. It covers a broad suite of pollutants – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 1 µm (PM₁), 2.5 µm (PM₂.₅) and 10 µm (PM₁₀) size fractions, sulfur dioxide (SO₂), as well as relative humidity, temperature and the UM003 parameter. Freshness varies: 24 rows have been updated within the last three days, while 29 rows are classified as old. The most recent timestamps cluster on 2026‑02‑10 20:00 UTC for most gases, but the NO reading dates back to 2024‑03‑11 12:00 UTC, making it the oldest among the currently available values.

Across the pollutants that have recent data, the median concentrations show a modest spread. PM₁₀’s median is about 30 µg/m³, ranging from near zero up to 64 µg/m³, with the latest value of 30.83 µg/m³ recorded at the Graz Don Bosco site on 2026‑02‑10 20:00 UTC. NO₂ averages 22.9 µg/m³ (median) and reaches a maximum of 83 µg/m³; the most recent measurement is 15.65 µg/m³ from Graz Mitte Gries on the same date. O₃ sits at a median of 18.3 µg/m³, spanning 0 to 27 µg/m³, with the latest 18.34 µg/m³ at Graz Süd Tiergartenweg. SO₂’s median is 2.0 µg/m³, with a peak of 5 µg/m³ and a current reading of 0.079 µg/m³ from the same southern site. PM₂.5 shows a median of 28.4 µg/m³, a high of 48.8 µg/m³, and the newest value of 48.80 µg/m³ at Josefigasse. CO’s median is 476.8 µg/m³, ranging from a placeholder low of –1000 to 794 µg/m³, with the latest 476.77 µg/m³ at Graz Don Bosco. NO, measured at only two stations, has a median of 1.95 µg/m³, a maximum of 3.61 µg/m³ and the most recent 3.61 µg/m³ from Graz Süd Tiergartenweg on 2024‑03‑11 12:00 UTC. PM₁ is represented by a single station, reporting a constant 28.17 µg/m³ at Josefigasse. The other listed variables – relative humidity, temperature and UM003 – are part of the schema but lack recent rows, so their current city‑wide values are not reflected in this snapshot.
