Air quality today

The air quality today in Guayaquil, Guayas, Ecuador is classified as Moderate. The primary pollutant measured is PM2.5. PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or less. The latest PM2.5 concentration is 34.7 µg/m³. PM10 data is not available. These values are based on five valid measurements. The measurement series includes five separate readings taken throughout the monitoring period. All readings were recorded and processed according to OpenAQ protocols. Data is shown via OpenAQ.

Overall, the Moderate rating reflects the current measurement levels. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Guayaquil dataset contains six measured pollutants – PM1, PM10, PM2.5, relative humidity, temperature and UM003 – all recorded by a single OpenAQ sensor located at the Hilton site. In total there are six data rows, one for each pollutant. Five of those rows have been refreshed within the last 30 days, with the most recent timestamp for PM1, PM2.5, relative humidity, temperature and UM003 being 2026-01-31 01:00 UTC. The PM10 record is older, last updated on 2025-01-13 23:00 UTC, which means that for this particular pollutant the information is more than a year out of date.

All six pollutants show a single value in the current snapshot, so the statistical spread is effectively zero: the minimum, median and maximum are identical for each. PM1 is reported at 22.683333333333334 µg/m³, PM10 at 24.49066686630249 µg/m³, and PM2.5 at 34.70549987157185 µg/m³. Relative humidity stands at 61.54850044250488 %, temperature at 26.95383319854736 °C, and the particle count UM003 at 4415.533333333333 particles/cm³. Because each pollutant has only one recorded point, the dataset does not capture variability over time or across different parts of the city.

The coverage is therefore limited to a single location and a narrow time window. While most parameters are recent, the older PM10 entry highlights an uneven update frequency across pollutants. Users should keep in mind that conditions can differ elsewhere in Guayaquil and at other times, so the figures represent a snapshot from the Hilton sensor rather than a comprehensive city‑wide picture.
