Air quality today
The air quality in La Paz, Baja California Sur is assessed as Moderate today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of approximately 10.34 µg/m³ and a PM10 level near 21.40 µg/m³ based on eight valid observations.
Data are shown via OpenAQ, reflecting the current monitoring results for the city. 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 La Paz air‑quality feed draws from a single monitoring site operated by the Junta Estatal de Caminos, giving eight distinct pollutant measurements for the city. All eight pollutants—carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂), combined oxides of nitrogen (NOX), ozone (O₃), particulate matter 10 µm and smaller (PM₁₀), fine particulate matter 2.5 µm (PM₂.₅), and sulfur dioxide (SO₂)—are represented, but each is reported from just one row of data.
The dataset is very fresh: the most recent timestamp for every pollutant is 2026‑02‑10 22:00 UTC, and OpenAQ flags each as “Updated within 7 days.” Because there is only one observation per pollutant, the minimum, median, and maximum values are identical. CO registers at 0.6411 ppm, NO at 0.0054 ppm, NO₂ at 0.0069 ppm, NOX at 0.0123 ppm, O₃ at 0.0385 ppm, PM₁₀ at 21.40 µg/m³, PM₂.₅ at 10.34 µg/m³, and SO₂ at 0.0403 ppm. The particulate measurements show a modest spread between the two size fractions, with PM₁₀ roughly double the concentration of PM₂.₅.
With only one monitoring location, the coverage is limited; variations across neighborhoods or times of day are not captured in this snapshot. While the data are current, the single‑station design means that city‑wide conditions may differ from what the sensor records at any given moment. Users should keep in mind that these figures represent a point measurement rather than a comprehensive view of La Paz’s air quality.

Data notes
The data set for La Paz includes eight valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered Updated within 3 days. This snapshot reflects conditions captured by those sensors at that time, but air quality can differ across neighborhoods and change throughout the day, so local readings may vary from what is shown here.
