Air quality today
The air quality in Nanaimo today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 4.6 µg/m³, based on four valid observations collected via OpenAQ. No PM10 value is available for this assessment. 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 dataset for Nanaimo includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM₂.5) – all reported from a single monitoring location on Labieux Road. Each pollutant has one recorded value, so the minimum, median and maximum are identical for every metric. The most recent reading was taken on 2026-02-10 at 22:00 UTC, which places the data well within the three‑day freshness window that OpenAQ uses to flag recent observations.
Because only one station contributes data, the coverage across the city is limited; there are no additional rows to show spatial variation or longer‑term trends. Nevertheless, the available numbers are precise: NO registers at 0.0049 ppm, NO₂ at 0.0094 ppm and O₃ at 0.021 ppm, while PM₂.5 measures 4.6 µg/m³. With a single value per pollutant there is no spread to describe – the range for each is effectively zero, indicating that the dataset captures a snapshot rather than a distribution of conditions.
In practical terms, this means the current picture of air quality in Nanaimo reflects only one point in time and space. While the readings are up‑to‑date, they cannot represent citywide variability or changes over days. Users should keep in mind that actual conditions may differ across neighborhoods or later in the day, and additional monitoring stations would be needed to provide a fuller view of the local atmosphere.
