Air quality today

The air quality in Niebla today is classified as Good. The primary pollutant identified is PM10, with a reference value of 10.68 µg/m³ based on six valid measurements reported through OpenAQ.

Overall conditions meet the criteria for the Good category, and the available data show that PM10 levels are within the referenced limit. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Niebla pulls information from three monitoring stations and contains a total of fourteen individual measurement rows. All four pollutants tracked by the OpenAQ network are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter up to 10 µm (PM₁₀) and sulfur dioxide (SO₂). The most recent observations for NO₂, SO₂ and PM₁₀ were all recorded on 2026‑02‑09 at 03:00 UTC, indicating that the majority of the data is refreshed within the last week. In contrast, the only NO reading comes from an older entry dated 2024‑02‑21 at 00:00 UTC, so this particular pollutant lacks a current snapshot.

Across the recent measurements, NO₂ values range from a low of 1.0 µg/m³ to a high of 9.0 µg/m³, with a median of 2.0 µg/m³ and the central 80 % of observations falling between roughly 1.3 and 6.9 µg/m³. SO₂ shows a narrower spread, all three recent rows reporting exactly 5.0 µg/m³, while the minimum recorded value is 3.0 µg/m³. PM₁₀ exhibits the widest variability: the smallest reading is 10.68 µg/m³, the largest reaches 33.15 µg/m³, and the median sits at 10.68 µg/m³, with most values (the 10th to 90th percentiles) between about 10.7 and 28.7 µg/m³. The lone NO measurement is a single value of 4.0 µg/m³.

Because the dataset contains only three stations, spatial coverage within Niebla is limited, and the age disparity—especially for NO—means that current conditions may differ across neighborhoods or times of day. Users should keep in mind that while most pollutants have recent data, the overall picture is based on a modest number of observations and may not capture short‑term fluctuations.

Data notes

The data shown for Niebla reflects six valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑09 at 03:00 UTC. While this snapshot provides a current view of ambient conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
