Air quality today
The air quality in San Luis Potosí City is currently classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 25.0 µg/m³ and a PM10 reference value of 71.0 µg/m³, based on seven valid observations reported through OpenAQ.
These figures reflect the present conditions without implying any trend or cause. 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 San Luis Potosí City contains a single monitoring station that reports eight pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). All measurements come from the Industriales Potosinos Asociados site, so coverage is limited to one location rather than a city‑wide network.
The most recent observation across the pollutants was recorded on 2026-02-10 22:00 UTC, with the exception of CO, whose last update dates back to 2025-12-23 12:00 UTC. This means that five of the eight parameters have data refreshed within the past week, while CO is over a month old. Each pollutant shows a single reported value, so there is no range or variability in the current snapshot: CO is 54.253 ppm, NO 0.005 ppm, NO₂ 0.007 ppm, NOX 0.012 ppm, O₃ 0.026 ppm, PM10 71.0 µg/m³, PM2.5 25.0 µg/m³ and SO₂ 0.001 ppm.
Because only one station contributes data, the figures represent conditions at that specific site rather than a comprehensive picture of air quality across San Luis Potosí. The dataset is therefore sparse in both spatial coverage (1 station) and temporal depth (single recent reading per pollutant), and users should keep in mind that concentrations can differ elsewhere in the city or change over time.

Data notes
The data shown for San Luis Potosí City is based on seven valid measurements and was refreshed within the past three days, with the most recent update recorded at 2026‑02‑10 22:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and throughout the day, so values may not represent the entire city’s current environment.
