Air quality today

The air quality in Coyhaique today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 0.0 µg/m³ and a PM10 reference value of 33.0 µg/m³, based on ten valid observations reported through OpenAQ.

Overall conditions meet the Good category criteria according to the latest data available. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Coyhaique contains data from two monitoring rows covering a total of 13 recorded measurements across the city’s stations. All nine standard air‑quality variables are represented: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter in three size fractions (PM1, PM2.5 and PM10), sulfur dioxide (SO2), relative humidity and temperature (the latter is listed but not reported in the current rows). The most recent observations are from 2026‑02‑10 16:00 UTC for PM2.5, PM1, relative humidity and SO₂, while the newest CO, O3 and NO2 values date back to 2021‑08‑20 and 2018‑04‑13 respectively, indicating that half of the pollutants have not been updated in several years.

Across the available data the concentration ranges are narrow. PM2.5 shows a minimum of 0.0 µg/m³, a median of 18.0 µg/m³ and a maximum of 19.0 µg/m³; PM10 varies between 23.0 and 33.0 µg/m³ with a median of 28.0 µg/m³. CO is recorded at a single value of 974.16 µg/m³, NO2 at 94.65 µg/m³, O3 at 23.29 µg/m³ and SO₂ at 17.04 µg/m³. Relative humidity is constant at 58.68 % in the latest row. The percentile spread (10th‑90th) for PM2.5 is 3.6–18.8 µg/m³, while for PM10 it is 24.0–32.0 µg/m³, showing that fine particles have a tighter distribution than coarse particles.

Because the dataset includes only two stations and several pollutants rely on data that are more than three years old, the picture of current air quality in Coyhaique is limited. Conditions can differ across neighborhoods and over time, so the available numbers represent snapshots rather than a comprehensive, up‑to‑date view of the city’s atmosphere.
