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 current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available, coming from two monitoring locations. The most recent reading was recorded on 2026-02-10 22:02 UTC, which falls within the “updated within 7 days” freshness category, so the dataset reflects very recent conditions.
Across the two stations, observed PM2.5 concentrations range from a low of 21.94 µg/m³ to a high of 26.38 µg/m³, with a median value of 24.16 µg/m³. The 10th percentile sits at about 22.38 µg/m³ and the 90th percentile near 25.94 µg/m³, indicating that most measurements cluster within a relatively narrow band. Because only PM2.5 is reported and there are just two rows of data, coverage is limited; other pollutants such as ozone or nitrogen dioxide are not represented. Consequently, while the available figures give a snapshot of fine‑particle levels at specific points, they do not capture the full spatial or temporal variability that may exist across San Juan.
