Air quality today

The air quality today in Mundaka, located in the Autonomous Community of the Basque Country, Spain, is classified as Good. The main pollutant identified is PM2.5 (fine particles). PM2.5 is the dominant component in the current profile. Data is shown via OpenAQ.

The reference values used for comparison are 1.0 µg/m³ for PM2.5 and 3.0 µg/m³ for PM10. The assessment is based on four valid measurements that constitute the latest available data set. These reference values serve as benchmarks for evaluating the air quality status. The count of four valid observations provides a representative snapshot of the current sampling period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Mundaka currently contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from two monitoring stations and a total of nine recorded rows. For NO₂ the most recent value is 6.0 µg/m³ recorded at the MUNDAKA site on 2026-01-28 12:00 UTC; the range spans 6.0 to 10.0 µg/m³ with a median of 8.0 µg/m³. Ozone shows a broader spread, with the latest reading of 70.0 µg/m³ at MUNDAKA on 2026-02-09 15:00 UTC, a minimum of 53.0 µg/m³, a maximum of 70.0 µg/m³ and a median of 61.5 µg/m³. PM10’s newest measurement is 3.0 µg/m³ (2026-02-09 15:00 UTC, MUNDAKA), ranging from 3.0 to 15.0 µg/m³ and centering around a median of 9.0 µg/m³. PM2.5 also reports its latest value of 1.0 µg/m³ at the same timestamp and site, with observations between 1.0 and 10.0 µg/m³ and a median of 5.5 µg/m³. The NO data are limited to a single older entry of 0.0 µg/m³ from the ES1491A station on 2024-01-16 23:00 UTC, and no newer measurements are available.

Overall, the most recent updates for four of the five pollutants fall within the last two weeks, indicating a relatively fresh snapshot of air quality for those substances. In contrast, the NO record is two years old, highlighting an uneven temporal coverage across the pollutant set. The spatial coverage is modest, with only two stations supplying the data, which means the readings reflect conditions at a limited number of locations rather than the entire city. The observed ranges differ markedly: NO₂ varies within a narrow 6‑10 µg/m³ band, while O₃, PM10 and PM2.5 each exhibit wider intervals, suggesting more variability in those components across the monitored sites.
