Air quality today
The air quality in Zumarraga is currently classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 6.0 µg/m³ and a PM10 value of 9.0 µg/m³, based on three valid observations.
Data are shown via OpenAQ. 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 air‑quality record for Zumarraga includes three measured pollutants – nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All of these are reported from a single monitoring location, identified as ZUMARRAGA in the dataset. Because there is only one row of data, the coverage across the city is limited to that point rather than a network of stations.
The most recent observations were all captured on 2026‑02‑09 at 15:00 UTC, meaning the values are fresh and fall within the “updated within 7 days” freshness bucket. For NO2 the recorded concentration is exactly 12.0 µg/m³; for PM10 it is 9.0 µg/m³; and for PM2.5 it is 6.0 µg/m³. Each pollutant shows a single value that serves as its minimum, median, maximum, 10th percentile and 90th percentile, indicating no variation in the data series at this site during the reporting period.
Because the dataset consists of only one measurement per pollutant, there is no spread to describe – the range for each contaminant collapses to a single point. Consequently, while the timestamps are current, the lack of multiple stations or repeated readings means the picture of air quality in Zumarraga is very narrow. Conditions can differ across neighborhoods and over time, so these figures represent just one snapshot rather than a comprehensive view of the city’s atmosphere.

Data notes
The current dataset for Zumarraga includes three valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑09 at 15:00 UTC. These figures represent a brief snapshot of ambient conditions; air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
