Air quality today

The air quality in Cali today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 8.48 µg/m³ based on five valid observations, and no PM10 reference value is available.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Cali includes six measured variables collected from a single monitoring location at Colegio Bolívar. The pollutants and environmental parameters available are PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. Overall there are six rows of data, one per variable, and the most recent observations were recorded on 2026‑02‑10 at 22:00 UTC for five of the six variables. The exception is PM10, whose latest reading dates back to 2025‑01‑13 at 23:00 UTC, indicating that this particular metric is older than a year.

All values in the current snapshot are single‑point measurements, meaning the minimum, median and maximum are identical for each variable. PM1 registers at 5.56 µg/m³, PM2.5 at 8.48 µg/m³ and PM10 at 3.88 µg/m³. Relative humidity is recorded as 45.50 % and temperature as 28.07 °C. The particle concentration UM003 stands at 1 103.59 particles per cm³. Because each metric has only one reported figure, there is no observable spread or variability within the dataset itself.

The coverage is limited to a single site, so conditions elsewhere in Cali may differ from those captured here. While most parameters are up‑to‑date, the older PM10 reading highlights an uneven freshness across pollutants. Users should keep in mind that the snapshot reflects only one location and point in time; broader spatial or temporal trends cannot be inferred from this limited set of rows.

Data notes

The data shown for Cali reflects five valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of citywide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
