Air quality today

The air quality in Temuco today is classified as Moderate. The primary pollutant measured is PM2.5, fine particulate matter, with a reference value of 12.0 µg/m³. Two valid measurements were recorded, and the corresponding PM10 reference value is 19.0 µg/m³.

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

What the data includes

The Temuco air‑quality dataset contains seven measured variables: carbon monoxide (CO), PM1, PM2.5, PM10, relative humidity, temperature and particle concentration (UM003). Altogether 16 rows of data are available from five monitoring stations, but the freshness varies widely across pollutants. The most recent measurements were recorded on 2026‑02‑10 13:00 UTC for both PM2.5 and PM10 at the Ñielol site; these two pollutants have the highest reporting frequency with six and four rows respectively, all updated within the last three days. Temperature, relative humidity, UM003, PM1 and CO each appear only once, and their timestamps are older – temperature, humidity, UM003 and PM1 date from 2025‑05‑26 20:00 UTC, while the single CO reading goes back to 2021‑08‑20 21:00 UTC.

Across the recent PM data the median values sit at 11.84 µg/m³ for PM2.5 (range 0 – 44.01 µg/m³) and 32.46 µg/m³ for PM10 (range 0 – 58 µg/m³), showing a fairly broad spread between low‑level and higher‑level observations. In contrast, the lone temperature record is 14.13 °C, humidity 48.81 % and UM003 1 346.42 particles/cm³, each representing a single point in time rather than a distribution.

Because most variables are represented by only one old entry, the dataset provides limited insight into temporal changes for those pollutants. The concentration of CO is fixed at 353.73 µg/m³ from Las Encinas Temuco, and PM1 is recorded as 7.12 µg/m³ at FCJE UFRO. Consequently, while recent PM2.5 and PM10 data give a snapshot of particulate conditions in early February, the overall picture for temperature, humidity, CO, PM1 and particle counts relies on dated measurements, meaning city‑wide air quality can differ across locations and times beyond what is captured here.

Data notes

The dataset for Temuco includes two valid measurements and is updated within three days, with the most recent values recorded on 2026‑02‑10 at 13:00 UTC. This snapshot reflects conditions at specific monitoring points and times; air quality can differ across neighborhoods and throughout the day, so local variations may not be captured in these figures.
