Air quality today

The air quality in Beaverton, Oregon is rated as Good today. The primary pollutant identified is PM2.5 (fine particles).

Measurements recorded by OpenAQ show a PM2.5 concentration of 0.0 µg/m³ based on eleven valid observations. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Beaverton air‑quality dataset currently contains five measured variables – fine particulate matter (PM2.5), ultrafine particles (PM1), relative humidity, temperature and particle concentration (UM003). Data come from three monitoring stations, each providing a row of observations. All rows are relatively recent: the most recent timestamp for every pollutant is 2026‑02‑11 01:00 UTC, which falls within the last seven days.

Across the three stations the recorded values show very low particulate levels: both PM2.5 and PM1 have a minimum, median and maximum of 0.0 µg/m³, with the 90th percentile also at zero for PM2.5. Relative humidity ranges from about 35.37 % to 40.40 %, with a median near 37.88 % and the inter‑decile spread (10th–90th percentiles) spanning roughly 35.87 % to 39.89 %. Temperature varies between 14.74 °C and 16.27 °C, centering on a median of 15.51 °C; the 10th and 90th percentiles are 14.89 °C and 16.12 °C respectively. Particle concentration (UM003) is measured in particles per cubic centimetre and ranges from 22.60  to 37.998 , with a median of 30.30  and an inter‑decile range of about 24.14 – 36.46.

Because the particulate measurements are all zero, they provide no information on spatial or temporal variation for those pollutants in Beaverton at this time. In contrast, humidity, temperature and UM003 show modest variability across the three sites, indicating that while the dataset is fresh, it captures only a narrow slice of atmospheric conditions. Users should keep in mind that air quality can differ by location and moment, and the current data represent a limited snapshot from a small number of stations.
