Air quality today

The air quality in Irapuato today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 13.38 µg/m³ and a PM10 level of 50.10 µg/m³, based on five valid observations collected through OpenAQ.

These values reflect the current state of ambient air in 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 Irapuato includes eight measured pollutants – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). Data come from 17 individual rows collected at three monitoring stations, all located in the Teódula area. For five of the pollutants – O₃, PM₁₀, PM₂.₅, SO₂ and CO – the most recent readings were recorded on 2026‑02‑10 at 22:00 UTC, meaning they have been updated within the last seven days. The remaining three gases – NO, NO₂ and NOX – are only represented by a single older entry each, dated 2023‑12‑17 at 20:00 UTC.

Across the recent measurements the observed values span a modest range. O₃ varies from a low of 0.004 ppm to a high of about 0.050 ppm, with a median near 0.005 ppm; PM₁₀ ranges between roughly 50 and 80 µg/m³, centering on a median of 60 µg/m³; PM₂.₅ shows values from 13.4 to 31.3 µg/m³ with a median of 29 µg/m³. SO₂ is recorded between 0.0071 and 0.0146 ppm (median 0.008 ppm), while CO runs from 1.10 to 1.28 ppm, medianing at about 1.19 ppm. The older gas‑phase data are single points: NO at 0.00818 ppm, NO₂ at 0.00656 ppm and NOX at 0.01471 ppm.

Because the dataset contains recent observations for only half of the listed pollutants, the picture of air quality in Irapuato is incomplete. The three stations provide consistent coverage for ozone, particulates and sulfur dioxide, but nitrogen oxides are represented by outdated single measurements, limiting insight into current levels of those gases. Consequently, while the available recent data give a clear snapshot of particulate and ozone conditions at Teódula, variations across other parts of the city or over the past few weeks cannot be assessed from this set alone.

Data notes

The current dataset for Irapuato includes five valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:00 UTC. These figures represent a snapshot of conditions across the monitoring network; air quality can differ by specific location and time of day within the city, so individual experiences may vary from the reported averages.
