Air quality today

The air quality in Osorno today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 15.0 µg/m³ and a PM10 level of 24.0 µg/m³, based on two valid observations.

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 Osorno contains six pollutant records drawn from a single monitoring station, covering carbon monoxide, nitrogen dioxide, ozone, particulate matter ≤10 µm, particulate matter ≤2.5 µm, and sulfur dioxide. The most recent measurements are for PM10 (24.0 µg/m³) and PM2.5 (15.0 µg/m³), both recorded on 2026-02-10 at 13:00 UTC, while the remaining four gases – CO, NO₂, O₃ and SO₂ – show values of 0.0 µg/m³ with their last updates dating back to 2017-06-28 at 15:00 UTC.

Across the six entries the data range is very narrow. For the two particulate metrics the minimum, median and maximum are identical (24.0 µg/m³ for PM10; 15.0 µg/m³ for PM2.5), indicating a single recent reading rather than a distribution of values. In contrast, the four gaseous pollutants all report zero across their entire recorded history, with no variation between minimum, median or maximum.

Because only one station contributes data, coverage is limited to that location and does not capture spatial differences within the city. Moreover, five of the six pollutant records are over six years old, so the overall freshness of the dataset is low except for the two particulate measurements, which were updated within three days of the current date. Users should keep in mind that conditions can differ across neighborhoods and times when interpreting these figures.

Data notes

The data shown for Osorno reflects two valid measurements and is marked as Updated within 3 days, with the most recent update recorded at 2026‑02‑10T13:00:00+00:00. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
