Air quality today

The air quality in Viña del Mar today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements from two valid samples show a PM2.5 concentration of 14.0 µg/m³ and a PM10 concentration of 23.0 µg/m³, as reported by OpenAQ.

This assessment reflects the current data available for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Viña del Mar contains a single monitoring station that reports six common air‑quality pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). All six species are listed, but the freshness of the observations differs markedly across them.

For CO, NO₂, O₃ and SO₂ the most recent values were recorded on 2017‑06‑28 at 15:00 UTC, and each shows a measured concentration of 0.0 µg/m³. These four pollutants therefore have data that is more than six years old, indicating that any current assessment would rely on outdated information. In contrast, the particulate matter measurements are much newer: both PM10 (23.0 µg/m³) and PM2.5 (14.0 µg/m³) were last updated on 2026‑02‑10 at 13:00 UTC, which is within three days of today’s date. The PM values show no variation in the record – the minimum, median, maximum, 10th percentile and 90th percentile are all identical to the single reported figure, reflecting a single data point rather than a distribution.

Overall, the city’s air‑quality profile is based on one station (six rows of pollutant data). Four pollutants have only historic readings, while two provide very recent but singular values. Because the dataset lacks multiple stations or repeated measurements over time, it cannot capture spatial or temporal variability within Viña del Mar. Users should be aware that conditions may differ across neighborhoods and that the available numbers represent a snapshot rather than an ongoing trend.

Data notes

The data shown for Viña del Mar reflects two valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T13:00:00+00:00. This snapshot provides a brief view of current air quality; conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
