Air quality today

The air quality in Arucas is classified as Good today. The primary pollutant identified is PM2.5. Measured concentrations show a PM2.5 level of 8.0 µg/m³ and a PM10 level of 16.0 µg/m³.

These values are based on five valid measurements reported through OpenAQ. The latest reading was recorded at 2026-02-23 12:00 UTC. All five observations are consistent with the Good category criteria. The reported PM2.5 and PM10 values are within the reference limits used for the Good classification. Data is shown via OpenAQ. The assessment reflects the current monitoring data without speculation on causes or future conditions. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Arucas contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO2). All values come from a single monitoring location, the Polideportivo Afonso‑Arucas site, giving a total of six rows of data. Each row reports a single concentration value in micrograms per cubic metre (µg/m³) together with the timestamp of the most recent observation.

Five of the six pollutants have been updated within the last 30 days: NO2 (6.0 µg/m³, last updated 2026-02-09 15:00 UTC), O3 (88.0 µg/m³, last updated 2026-02-09 15:00 UTC), SO2 (6.0 µg/m³, last updated 2026-02-09 15:00 UTC), PM10 (16.0 µg/m³, last updated 2026-02-03 01:00 UTC) and PM2.5 (8.0 µg/m³, last updated 2026-02-03 01:00 UTC). The NO measurement is older, recorded on 2024-01-16 00:00 UTC, and is flagged as “old data”. This mix of recent and older timestamps shows that most of the current snapshot is fresh, while one pollutant lags behind.

All six pollutants show identical minimum, median and maximum values, indicating that the dataset captures a single point‑in‑time reading rather than a range of observations. Consequently, there is no reported variability for any pollutant at this site. Because the data originate from only one station, they reflect conditions at that specific location and may not represent the full spatial diversity of air quality across the wider city of Arucas.
