Air quality today

The air quality in Oradea is classified as Good today. The primary pollutant identified is PM10, with a measured concentration of 51.40401 micrograms per cubic meter based on fourteen valid observations reported through OpenAQ.

These values indicate that the current conditions meet the criteria for the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Oradea contains recent measurements of five key air‑quality constituents – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and sulphur dioxide (SO₂). All values come from a total of 26 rows, but only five distinct monitoring stations contributed data, so the spatial coverage is limited to a handful of points across the city.

The freshest records were all captured on 2026‑02‑10 at 19:00 UTC, meaning each pollutant has at least one observation that is less than a week old. CO shows the widest spread, with values ranging from a minimum of –1000 µg/m³ (an outlier likely due to sensor error) up to a maximum of 687.45 µg/m³ and a median of 336.64 µg/m³. NO₂ varies between 12.72 and 58.62 µg/m³, centering around a median of 19.72 µg/m³; the 10th‑percentile is 13.91 µg/m³ while the 90th‑percentile reaches 39.48 µg/m³. O₃ values are confined to a narrower band from 21.34 to 117.63 µg/m³, with a median of 30.05 µg/m³ and both the 10th‑ and 90th‑percentiles matching the minimum and 93.97 µg/m³ respectively. PM10 readings are modest, spanning –1.0 to 51.40 µg/m³, median 23.27 µg/m³; SO₂ is low throughout, from –1.0 up to 6.33 µg/m³ with a median of 4.10 µg/m³.

Because only five stations contribute, the data reflect conditions at specific locations rather than city‑wide averages, and the presence of extreme negative minima for CO, PM10 and SO₂ suggests occasional sensor anomalies. Nonetheless, the most recent timestamps are uniformly within the last seven days, providing a current snapshot while acknowledging that actual air quality can differ across neighborhoods and times not captured by these limited rows.

Data notes

The current dataset for Oradea includes 14 valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10T19:00:00+00:00. These figures represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
