This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Whitehorse today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 3.0 µg/m³, based on four valid observations recorded by OpenAQ.
Overall conditions meet the Good category criteria with no additional pollutants reported. 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 Whitehorse air‑quality record draws on a single monitoring site that supplies five separate pollutant readings. All of the data come from the Whitehorse NAPS station, so the coverage reflects conditions at one location rather than a city‑wide network. For nitrogen monoxide (NO) the dataset contains a single value of 0.0027 ppm, recorded most recently on 2026‑02‑10 22:00 UTC; the same timestamp applies to nitrogen dioxide (NO₂) at 0.008 ppm and to total nitrogen oxides (NOX) at 0.0107 ppm. Particulate matter with a diameter of 2.5 µm or less (PM2.5) is reported as 3.0 µg/m³, also from the 2026‑02‑10 22:00 UTC update. Ozone (O₃) is the only metric that lags behind, with its latest entry dated 2026‑01‑22 17:00 UTC and a value of 0.02 ppm.
Because each pollutant appears in just one row, there is no spread of values to describe variability – the minimum, median and maximum are identical for every constituent. The data therefore give a snapshot rather than a range, and the freshness varies: four of the five measurements were refreshed within the past three days, while ozone’s most recent reading is about three weeks older. This uneven timing means that any short‑term changes in ozone levels would not be captured as promptly as the nitrogen compounds or particulate matter.
Overall, the dataset provides a concise but limited picture of Whitehorse’s air quality. With only one monitoring location and a single data point per pollutant, the information cannot represent spatial differences across the city, and the older ozone entry highlights that some parameters may be less up‑to‑date than others. Users should keep in mind that conditions can differ by place and time beyond what these five recent values convey.

Data notes
The data shown reflects four valid measurements and was updated within three days, with the most recent reading recorded at 2026‑02‑10T22:00:00+00:00. These values provide a snapshot of current conditions in Whitehorse, Yukon, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured by this summary.
