This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality today in Erandio is classified as Good. The primary pollutant identified is PM2.5. The measured PM2.5 level is 2.0 µg/m³, and the PM10 level is 4.0 µg/m³. These concentrations correspond to the reference values of 2.0 µg/m³ for PM2.5 and 4.0 µg/m³ for PM10. These values are based on five valid measurements. All five measurements were within the acceptable range. The dataset includes five recent readings that meet quality criteria.
Data is shown via OpenAQ. The reported figures represent the latest available observations. The values are current for today. No additional pollutants exceeded their reference limits. 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 dataset for Erandio in the Autonomous Community of the Basque Country contains six measured pollutants – carbon monoxide, nitrogen monoxide, nitrogen dioxide, particulate matter 10 µm, particulate matter 2.5 µm and sulfur dioxide – all reported in micrograms per cubic metre. These measurements come from a single monitoring station, giving a total of six rows of data, one for each pollutant.
Across the five most recent pollutants the last‑updated timestamps fall within the past month, with carbon monoxide, PM10, PM2.5 and sulfur dioxide all recorded at 2026‑02‑09 15:00 UTC and nitrogen dioxide at 2026‑01‑28 12:00 UTC. The only older entry is nitrogen monoxide, which was last updated on 2024‑01‑16 23:00 UTC, indicating that the temporal coverage is uneven and that the most recent picture of NO levels may not reflect current conditions.
Each pollutant currently shows a single observed value: carbon monoxide is 200.0 µg/m³, nitrogen monoxide 1.0 µg/m³, nitrogen dioxide 33.0 µg/m³, PM10 4.0 µg/m³, PM2.5 2.0 µg/m³ and sulfur dioxide 2.0 µg/m³. Because the minimum, median and maximum are identical for every pollutant, the snapshot does not reveal any spread or variability in the measurements. This limited range suggests that the present data capture a very specific moment rather than a broader distribution of air‑quality conditions, and that variations across the city or over time may not be represented in the current set.

Data notes
The dataset for Erandio includes five valid measurements and is updated within 30 days. The most recent data were recorded on 2026-02-09 at 15:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can vary by location and time within the city, so values may differ from current or neighborhood-specific conditions.
