Air quality today

The air quality in Des Moines, Washington, is currently classified as Good. The primary pollutant identified is PM2.5, measured at 4.0 µg/m³ based on two valid observations. PM2.5 denotes fine particulate matter with diameters of 2.5 micrometers or less, which can remain suspended in the atmosphere. Both measurements were recorded through the OpenAQ platform, providing a snapshot of ambient conditions for the area.

No PM10 measurement is available for this assessment, so only the fine particle metric is reported. The consistency between the two readings suggests stable ambient conditions during the sampling window. Other pollutant categories were not flagged in the current dataset. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data for Des Moines, Washington, comes from OpenAQ and contains six measured pollutants: PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particles per cubic centimetre). All six rows originate from a single monitoring location, and the freshness bucket shows that every record is classified as “unknown,” meaning the most recent timestamps are not available. Because the timestamps are missing, the dataset does not indicate when the values were recorded, so the overall recency of the information cannot be determined.

Each pollutant is represented by a single value, so the minimum, median and maximum are identical. PM1 is recorded at 1.57 µg/m³, PM10 at 2.61 µg/m³ and PM2.5 at 2.14 µg/m³. Relative humidity stands at 55.44 %, temperature at 13.28 °C, and the UM003 particle concentration is 625.56 particles/cm³. The uniformity of the numbers shows that there is no spread or range to describe variability; the dataset provides only one snapshot per parameter. The particulate matter concentrations are in the low single‑digit microgram per cubic metre range, while the humidity and temperature reflect a moderate indoor‑like environment.

Given that all six entries lack a recent timestamp and come from just one site, the data cannot capture temporal changes or spatial differences across the city. Conditions in Des Moines can differ by neighbourhood and time of day, so users should treat these figures as a limited snapshot rather than a current or comprehensive picture of air quality in the area.

Data notes

This dataset includes two valid measurements and is updated within 30 days. The most recent data were recorded on 2026-02-10T23:00:00+00:00. Because the monitoring network is limited, the values represent a snapshot and air quality can vary by location and time within the city.
