Air quality today
The air quality in Beasain today is classified as Good. The primary pollutant identified is PM2.5. This assessment is based on four valid measurements collected through OpenAQ. The overall rating reflects the current concentration of the listed pollutants.
The latest reported concentration for PM2.5 is 6.0 µg/m³, while PM10 measures 7.0 µg/m³. These values correspond to the reference levels used for the evaluation. All four measurements are consistent with the reported concentrations. The reported figures are within the reference thresholds applied for the Good category. No exceedances were recorded for the measured parameters. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The data for Beasain in the Autonomous Community of the Basque Country, Spain, comes from a single monitoring station and consists of five rows, each representing a different pollutant. The pollutants available are carbon monoxide (CO) at 240.0 µg/m³, nitrogen dioxide (NO₂) at 13.0 µg/m³, particulate matter 10 µm (PM10) at 7.0 µg/m³, particulate matter 2.5 µg (PM2.5) at 6.0 µg/m³, and sulfur dioxide (SO₂) at 3.0 µg/m³. All five rows are recorded within the last 30 days, and none are classified as old or unknown.
Freshness varies slightly across the pollutants. CO, PM10, PM2.5 and SO₂ were all last updated on 2026-02-09 15:00 UTC, indicating a very recent snapshot. NO₂ is older, with its most recent entry dated 2026-01-28 12:00 UTC, which is still within the 30‑day window but lags by about two weeks compared with the other measurements. No data points fall outside the 30‑day freshness bucket, so the overall dataset is current.
Because each pollutant shows identical minimum, median and maximum values (for example, CO is consistently reported as 240.0 µg/m³), the dataset provides a single point rather than a range, highlighting a lack of observed variation over time at this location. The uniformity of values suggests that the monitoring record captures only a snapshot, not a distribution of concentrations. Additionally, the update schedule is uneven: four pollutants share the same recent timestamp, while NO₂ is reported less frequently, pointing to possible gaps in reporting cadence. With only one station contributing data, the figures represent conditions at that specific site and may not reflect spatial differences across the broader city area.
