Air quality today
The air quality in Covington, Washington is rated as Good today. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 0.0113 µg/m³ based on five valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Covington air‑quality dataset contains a single monitoring location that reports six different measurements: fine particulate matter (PM1) in micrograms per cubic metre, coarse particulate matter (PM10), fine particulate matter (PM2.5), relative humidity as a percentage, ambient temperature in degrees Celsius, and particle count (UM003) expressed in particles per cubic centimetre. All values are drawn from one row of data, so the city’s coverage is limited to this lone sensor.
The freshest observations were recorded on 2026‑02‑11 at 00:00 UTC for five of the six pollutants, indicating that most of the dataset reflects conditions within the past week. The exception is PM10, whose latest reading dates back to 2025‑01‑13 at 23:00 UTC, making it considerably older than the other parameters. Across the recent data, the recorded values show virtually no variation: PM1 registers a constant 0.0 µg/m³, PM2.5 is consistently 0.011309523874568562 µg/m³, relative humidity stays at 27.978769741361102 %, temperature remains steady at 20.902513298408063 °C, and the particle count (UM003) holds at 87.760582010582 particles/cm³. Because each metric has a single recorded value, the median, minimum and maximum are identical, offering no insight into day‑to‑day fluctuations.
Given that only one monitoring site supplies data for Covington, the picture of air quality is necessarily narrow. The recent timestamps suggest the sensor is actively reporting most parameters, yet the outdated PM10 measurement highlights an inconsistency in coverage. Users should keep in mind that conditions can differ across neighborhoods and over time, and the current dataset does not capture those spatial or temporal variations.
