Air quality today

The air quality in Cartagena today is classified as Good. The primary pollutant measured is PM2.5, with a reference concentration of 5.38 µg/m³. In addition, the PM10 level is recorded at 18.13 µg/m³ based on 23 valid observations.

Data are shown via OpenAQ and reflect the current monitoring results 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 Cartagena includes measurements of carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). These values come from five monitoring rows, of which 23 individual readings have been updated within the last seven days while the remaining 26 are older than that period. The most recent timestamp across all pollutants is 2026‑02‑09 15:00 UTC, except for NO where the latest entry dates back to 2024‑02‑20 00:00 UTC.

Across the recent data the observed ranges show a fairly wide spread. CO varies from a low of 10 µg/m³ up to a high of 560 µg/m³ with a median of 235 µg/m³, while NO₂ spans 2.6‑48 µg/m³ (median 6.45 µg/m³). Ozone levels are consistently higher, ranging from 54.5 to 93.6 µg/m³ and centering around a median of 77.25 µg/m³. Particulate matter shows lower concentrations: PM10 runs between 5.9 and 31.32 µg/m³ (median 20.18 µg/m³) and PM2.5 between 3.08 and 14.97 µg/m³ (median 5.38 µg/m³). SO₂ is the least variable, with values from 0.5 to 6.0 µg/m³ (median 2.85 µg/m³), and NO remains low at 1.7‑3.6 µg/m³ (median 2.6 µg/m³).

The coverage is uneven: CO, O₃, NO₂, PM10, PM2.5 and SO₂ all have eight recent rows each, whereas NO has only four recent entries and its latest reading is two years old. Consequently, while most pollutants provide a fairly current picture of air quality in Cartagena, the data for nitrogen oxide is sparse and dated, meaning conditions for that specific gas may not be well represented at this time.

Data notes

The dataset for Cartagena includes 23 valid measurements and is refreshed Updated within 3 days, with the latest values recorded on 2026‑02‑09T15:00:00+00:00. These figures represent a snapshot of air quality across the city at that time; conditions can differ by neighbourhood, micro‑climate and moment‑to‑moment variations, so local readings may not exactly match this summary.
