Air quality today

The air quality in Parry Sound today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 19.0 µg/m³ based on five valid observations.

No other pollutants are reported for this assessment, and the available measurements reflect current conditions as captured by the monitoring network. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Parry Sound air‑quality record consists of five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), combined nitrogen oxides (NOX), ozone (O3) and fine particulate matter (PM2.5). All data come from a single monitoring station, so the dataset contains one row per pollutant. The most recent readings for each compound were logged on 2026‑02‑10 at 22:00 UTC, meaning the freshest values are just under two days old.

Across the five pollutants the observed concentrations span modest ranges. NO2 varied from a low of 0.001 ppm to a high of 0.009 ppm, with a median near 0.005 ppm; O3 was tightly clustered between 0.034 and 0.036 ppm, medianing at 0.035 ppm. PM2.5 showed the widest spread, ranging from 9 µg/m³ up to 19 µg/m³, with a typical value around 14 µg/m³. The nitrogen‑based gases were constant in this snapshot: NO held steady at 0.001 ppm and NOX at 0.01 ppm for the single measurement each.

Because only one station contributes data, coverage is limited to a single location within Parry Sound, and there are no older or unknown timestamps in the set – every entry is marked as “Updated within 3 days.” This uniform freshness eliminates gaps but also means the dataset does not capture spatial variation across the city or longer‑term trends. Users should keep in mind that conditions can differ elsewhere in town or change after the last update.

Data notes

The current air‑quality snapshot for Parry Sound is based on five valid measurements and was updated within three days, with the latest data recorded at 2026‑02‑10T22:00:00+00:00. This information reflects conditions at the time of sampling; however, pollutant levels can differ across neighbourhoods and may change throughout the day, so actual exposure may vary locally.
