Air quality today
The air quality in Shawinigan today is classified as Good. The primary pollutant identified is PM2.5, which refers to fine particulate matter measured in the atmosphere.
Two valid measurements were recorded, showing a PM2.5 concentration of 8.0 µg/m³. 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 air‑quality record for Shawinigan draws from a single monitoring location, giving two rows of data – one for ozone (O₃) and one for fine particulate matter (PM₂.5). Both measurements were last refreshed on 2026-02-10 at 22:00 UTC, so the most recent values are less than three days old. Ozone is reported in parts per million, with a single reading of 0.034 ppm; the minimum, median and maximum are all identical, indicating no observed variation across the available sample. PM₂.5 is expressed in micrograms per cubic metre and shows a constant value of 8.0 µg/m³, again with matching min, median and max.
Because only one station contributes data, the coverage for Shawinigan is limited to that specific site (Shawinigan – Saint‑M). There are no older or unknown timestamps in the set, so the dataset reflects a snapshot rather than a range of conditions over time. The lack of multiple rows per pollutant means there is no spread to describe; each pollutant has a single point measurement, which serves as the current reference but does not capture temporal fluctuations.
In practical terms, users can see that both ozone and PM₂.5 are available for Shawinigan, each with one recent value from the same monitoring spot. While this provides an up‑to‑date snapshot, it does not convey how concentrations might differ across other parts of the city or change throughout the day. For a fuller picture, additional stations or more frequent updates would be needed.
