Air quality today

The air quality in Azpeitia today is classified as Good. The primary pollutant identified is PM2.5. Four valid measurements were recorded, showing a PM2.5 concentration of 7.0 µg/m³ and a PM10 concentration of 18.0 µg/m³. These values correspond to the reference values of 7.0 µg/m³ for PM2.5 and 18.0 µg/m³ for PM10 used in the evaluation. A total of four valid readings contributed to the assessment.

Data is shown via OpenAQ. Measurements are aggregated from local monitoring stations. The information reflects the latest available data for the city. Values are presented in micrograms per cubic meter. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Azpeitia air‑quality record draws on nine recent observations collected at two monitoring sites. Five of those observations fall into the “old” freshness bucket, while the remaining four were refreshed within the last thirty days, giving the dataset a mixed timeliness profile. All five key pollutants—nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM10) and particulate matter 2.5 µm (PM2.5)—are represented, but the depth of coverage varies: NO appears in a single row dated 2024‑01‑16 23:00 UTC, whereas the other four gases each have two rows updated most recently on 2026‑02‑09 15:00 UTC (NO₂ on 2026‑01‑28 12:00 UTC).

Across the recent data the measured concentrations show modest ranges for most pollutants. NO₂ values sit between 22.0 and 23.0 µg/m³ with a median of 22.5 µg/m³, PM10 spans 18.0 to 23.0 µg/m³ (median 20.5 µg/m³) and PM2.5 ranges from 7.0 to 11.0 µg/m³ (median 9.0 µg/m³). Ozone displays the broadest spread, moving from a low of 36.0 µg/m³ to a high of 55.0 µg/m³ and a median of 45.5 µg/m³, indicating more variability in this pollutant over the sampled period. The single NO entry remains fixed at 3.0 µg/m³, reflecting an older measurement that does not capture recent fluctuations.

Overall, the dataset offers a snapshot of Azpeitia’s air quality with recent, multi‑pollutant data from two stations, yet the older NO record and the uneven number of rows per pollutant mean that conditions can differ across locations and times, especially for gases with fewer or dated observations.
