Air quality today

The air quality in Pécs is currently classified as moderate. The primary pollutant measured today is PM2.5, with a reference concentration of 29.0 µg/m³, while the accompanying PM10 level stands at 34.0 µg/m³ based on four valid observations.

Data are 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 Pécs contains measurements of carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO₂). In total 22 rows of data were collected from four monitoring stations, with each pollutant represented by between three and four recent observations.

The newest readings are from early February 2026 for NO₂, PM10, PM2.5 and O₃ (2026‑02‑10 20:00 UTC), showing that these four pollutants have been updated within the last three days. CO’s latest value is older, recorded on 2024‑08‑07 09:00 UTC, while SO₂ is the most dated measurement, last logged on 2023‑04‑05 19:00 UTC. This mix of fresh and legacy data means that current conditions are well captured for NO₂, PM10, PM2.5 and O₃, but less so for CO and especially SO₂.

Across the available records, concentrations span a wide range. CO varies from 119 µg/m³ up to about 1,255 µg/m³, with a median near 657 µg/m³; NO₂ ranges between 22.7 and 65.5 µg/m³, centering on a median of roughly 45.5 µg/m³; PM10 values sit from 18 to 84.9 µg/m³ with a typical level around 37 µg/m³; PM2.5 shows the greatest relative spread, from just under 1 µg/m³ to 33 µg/m³ and a median of about 16.3 µg/m³; SO₂ is low overall, between 2.86 and 4.8 µg/m³ with a median near 3.95 µg/m³; O₃ remains tightly clustered around 17 µg/m³ (16.77–17.10 µg/m³). The percentiles confirm that most observations cluster toward the middle of these ranges, but outliers—particularly high CO and PM2.5 values—are present.

Because the data set includes both recent and older entries, the picture it provides is strongest for pollutants with up‑to‑date measurements (NO₂, PM10, PM2.5, O₃) and weaker for those where the latest reading is several years old (CO, SO₂). Consequently, while city‑wide conditions can be described in general terms, local variations at specific times may not be fully captured for all pollutants.

Data notes

The current dataset for Pécs includes four valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 20:00 UTC; it is therefore “Updated within 3 days.” While these figures give a reliable snapshot of overall conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in this summary.
