Air quality today
The air quality in Saguenay is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 26.3 µg/m³, based on four valid observations reported through OpenAQ. No PM10 value is available at this time. 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 Saguenay includes two pollutants – ozone (O₃) and fine particulate matter (PM₂.5) – reported from two monitoring rows. Both rows are recent, with the latest update recorded on 2026-02-10 22:00 UTC, meaning the data are fresh within the past three days for each pollutant.
For ozone, concentrations range from a low of 0.023 ppm to a high of 0.028 ppm, with a median value of about 0.0255 ppm. The 10th percentile sits at 0.0235 ppm and the 90th percentile at 0.0275 ppm, indicating that most measurements cluster tightly around the middle of the observed range.
PM₂.5 values show a broader spread. The minimum recorded level is 13.4 µg/m³, while the maximum reaches 26.3 µg/m³; the median sits at 19.85 µg/m³. The lower decile is 14.69 µg/m³ and the upper decile 25.01 µg/m³, suggesting a moderate variability in particulate concentrations across the two rows.
Overall, the coverage is limited to just two sensor locations, both providing up‑to‑date readings. Because only two rows contribute data, the picture of air quality in Saguenay reflects conditions at those specific sites and may not capture variations that occur elsewhere in the city or at different times of day. Nonetheless, the available measurements give a clear snapshot of recent ozone and PM₂.5 levels across the monitored points.

Data notes
The current dataset for Saguenay includes four valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot reflects conditions at that time, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
