Air quality today

The air quality today in Los Barrios is classified as Moderate. The primary pollutant identified is PM2.5. The reported PM2.5 concentration is 11.44 µg/m³, and the PM10 concentration is 5.25 µg/m³. These figures represent the latest reported values for the day and are based on 21 valid observations collected during the reporting period.

PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or less, while PM10 includes particles up to 10 micrometers in diameter. Data is shown via OpenAQ. The observations were recorded by monitoring stations contributing to the OpenAQ platform. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Los Barrios includes seven measured pollutants – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulphur dioxide (SO₂). Data come from five monitoring stations and a total of 27 rows, of which 22 rows have been updated within the last 30 days and five rows are older than 30 days. The most recent timestamps range from 2026‑02‑09 01:00 UTC for CO to 2026‑02‑09 12:00 UTC for NO₂, SO₂ and PM10, while the NO data were last refreshed on 2024‑02‑21 00:00 UTC.

Across the pollutants the coverage is uneven. NO, NO₂ and SO₂ each have five rows, reflecting measurements at all five stations, whereas O₃ appears in three rows, PM10 and PM2.5 in four rows each, and CO in a single row. The CO reading is consistently 710 µg/m³ from the CORTIJILLOS station (2026‑02‑09 01:00 UTC). Ozone shows a narrow band between 85 µg/m³ and 96 µg/m³ with a median of 88 µg/m³ across three stations (latest on 2026‑02‑09 05:00 UTC). Particulate matter exhibits broader variability: PM10 ranges from 0 µg/m³ to 44.18 µg/m³ with a median of 21.525 µg/m³, while PM2.5 spans 0.81 µg/m³ to 33.28 µg/m³ and a median of 9.32 µg/m³. Nitrogen monoxide varies between 1 µg/m³ and 7 µg/m³ (median 2 µg/m³), and nitrogen dioxide between 0 µg/m³ and 7 µg/m³ (median 1 µg/m³). Sulphur dioxide ranges from 0 µg/m³ to 5 µg/m³ with a median of 2 µg/m³.

Overall the dataset provides recent information for most pollutants, but the limited number of rows for O₃, PM10, PM2.5 and especially CO means that spatial coverage is not uniform across the city, and the five older rows indicate that some conditions may not be captured in the most current snapshot.

Data notes

These data are based on 21 valid measurements and have been updated within 30 days, with the most recent reading recorded on 2026-02-09 at 12:00 UTC. The dataset reflects the conditions captured at the time of measurement and does not represent continuous monitoring. Air quality can vary by location and time within the city, so this snapshot may not capture all local fluctuations.
