Air quality today

The air quality in Győr is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 19.0 µg/m³ and a PM10 reference value of 29.0 µg/m³, based on four valid observations collected via OpenAQ.

These figures reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Győr’s open‑air quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), fine particulate matter 2.5 µm or smaller (PM2.5) and sulphur dioxide (SO₂). The dataset is built from 29 individual rows that originate from five monitoring stations, all located at the Győr 2 Ifjúság site for the most recent values.

The newest observations are fairly current for most gases: CO was last recorded on 2026‑02‑09 12:00 UTC, O₃, PM10, PM2.5 and SO₂ each have updates from 2026‑02‑10 20:00 UTC, while NO₂ is older, dated 2025‑10‑15 09:00 UTC. Overall, four of the six pollutants have data refreshed within the last three days, and CO is updated within a week; only NO₂ falls into an “old” category. Across all rows, 13 entries are classified as old, 11 are unknown in terms of freshness, and just one row is known to be less than three days old, indicating that many historic points remain in the record.

The measured values show a wide spread. CO ranges from a low of 263 µg/m³ to a high of 1 260 µg/m³, with a median around 547 µg/m³; NO₂ varies between 8.9 and 49.5 µg/m³ (median ≈ 24 µg/m³); O₃ stays between 26.4 and 57.6 µg/m³ (median ≈ 33 µg/m³). Particulate matter is generally lower, with PM10 from about 2 to 29 µg/m³ (median 9) and PM2.5 from roughly 0.36 to 19 µg/m³ (median ≈ 9); SO₂ spans 1.96 to 98.9 µg/m³ (median ≈ 2.7). These figures illustrate that while some pollutants such as CO and NO₂ exhibit relatively high concentrations, the particulate fractions remain modest in this snapshot. Because the data come from a single monitoring location and include many older or unknown‑age rows, conditions can differ across other parts of Győr and at times not captured by the most recent measurements.
