Air quality today

The air quality in Ciudad Juárez today is classified as Moderate. According to the latest assessment, the primary pollutant is PM2.5. The Duck score for the city places it in the Moderate range. A total of fourteen observations contributed to the current values. This rating is presented through OpenAQ.

The reported concentrations are 9.43 µg/m³ for PM2.5 and 50.0 µg/m³ for PM10. These figures reflect the current monitoring data for the city. Both PM2.5 and PM10 are reported as reference values in the dataset. These measurements are part of the ongoing monitoring effort for the region.

What the data includes

The air‑quality feed for Ciudad Juárez pulls 19 recent measurement rows from seven monitoring sites and reports eight pollutants: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All values are refreshed within the last 30 days except CO and SO₂, whose most recent timestamps are from 2026‑01‑30 00:00 UTC. The other six gases and both particle metrics were last updated on 2026‑02‑10, with times ranging from 19:00 to 22:06 UTC.

The dataset shows a marked imbalance in coverage. PM₂.₅ is the most represented pollutant, with seven rows spanning a minimum of 5.0 µg/m³, a median of 11.32 µg/m³ and a maximum of 4 759.2 µg/m³; the 10th percentile sits at 7.27 µg/m³ while the 90th percentile reaches 3 209.2 µg/m³, and an extreme reading of 2 175.85 µg/m³ was recorded at Los Bosques. By contrast, NO, NO₂, NOX and O₃ each have only two rows, and CO and SO₂ each appear in a single row. The nitrogen oxides series display a narrow spread: NO ranges from 0.000004 ppm to 0.0044 ppm (median 0.0022 ppm), NO₂ from 0.000013 ppm to 0.0138 ppm (median 0.0069 ppm) and NOX from 0.000017 ppm to 0.0083 ppm (median 0.0042 ppm). O₃ values cluster tightly between 0.0335 ppm and 0.034 ppm, with a median of 0.03375 ppm. PM₁₀ is reported from two stations, ranging from 27.0 µg/m³ to 50.0 µg/m³ (median 38.5 µg/m³).

Because the number of rows varies widely across pollutants and some gases rely on a single, older measurement, the snapshot captures only part of the city’s atmospheric picture. Conditions can differ noticeably between monitoring locations and over time, so the available data should be viewed as a limited but recent glimpse of air quality in Ciudad Juárez.
