What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available from OpenAQ, coming from two monitoring rows in Guanajuato City. One of those rows was refreshed within the last seven days, while the other is classified as old, so the most recent timestamp in the set is 2026-02-10 19:00 UTC. The PM2.5 values recorded span a narrow band, with the lowest reading at 19 µg/m³ and the highest at 23 µg/m³; the median sits at 21 µg/m³, and the 10th‑percentile and 90th‑percentile are roughly 19.4 µg/m³ and 22.6 µg/m³ respectively.

With just two stations contributing data, coverage is limited to a small portion of the city, and the mix of recent and older entries means the picture may not capture all local variations at any given moment. The tight concentration of values suggests relatively consistent PM2.5 levels across the sampled sites during the reporting window, but users should keep in mind that conditions can differ elsewhere or change after the last update.
