Air quality today

The air quality in Saskatoon today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 7.54 µg/m³ based on eight valid observations reported through OpenAQ. This reflects the current state of ambient particulate matter in the city.

What the data includes

The dataset for Saskatoon currently contains eight measured pollutants – nitrogen dioxide (NO2), ozone (O3), PM1, PM2.5, PM10, relative humidity, temperature and particle count (UM003). Altogether there are nine rows of data from two monitoring stations: the city‑wide station that reports NO2, O3 and PM2.5, and the Greystone Heights site that supplies PM1, PM10, relative humidity, temperature and UM003. The most recent measurements were all taken on 2026‑02‑10 at 22:00 UTC, except for PM10 which dates back to 2025‑01‑13 at 23:00 UTC, so the bulk of the data is fresh within the last three days while one pollutant relies on older information.

Across the recent records the values are tightly clustered. For PM2.5 the median concentration is 6.27 µg/m³ with a narrow range from 5.0 to 7.54 µg/m³; NO2 and O3 each show a single reported value of 0.007 ppm and 0.023 ppm respectively, indicating no observed variation in the latest snapshot. At Greystone Heights the PM1 reading is exactly 5.498 µg/m³, PM10 sits at 4.161 µg/m³, relative humidity is 46.13 % and temperature is 5.58 °C, while particle count (UM003) measures 1030.70 particles/cm³ – each reported with identical minimum, median and maximum values.

Because only two stations contribute data, the coverage is limited to specific neighbourhoods rather than city‑wide averages. Most pollutants have a single recent observation, so short‑term fluctuations across Saskatoon cannot be captured from this set alone. Users should keep in mind that conditions may differ elsewhere or change after the last update, especially for PM10 where the latest reading is more than a year old.

Data notes

The current dataset for Saskatoon includes eight valid measurements and is updated within three days, with the latest refresh recorded on 2026‑02‑10 at 22:00 UTC. These values represent a recent snapshot of ambient conditions across the city’s monitoring network. Keep in mind that air quality can differ by specific location and time of day within Saskatoon, so individual experiences may vary from the reported averages.
