The air quality in Oakville today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 22.0 µg/m³ based on five valid observations.
No additional pollutants reached reporting thresholds, and the available measurements reflect current conditions without further interpretation. 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 Oakville air‑quality dataset currently includes five measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), ozone (O₃) and fine particulate matter (PM₂.5). All five parameters are represented by a single monitoring record each, giving a total of five rows of data for the city.
Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, which is within the last three days and therefore reflects very fresh conditions for Oakville. The values are all identical across their statistical summaries: NO registers 0.012 ppm, NO₂ 0.035 ppm, NOX 0.047 ppm, O₃ 0.021 ppm and PM₂.5 22.0 µg/m³. Because each metric has only one observation, the minimum, median, maximum and percentile figures are the same for every pollutant, indicating no observed spread in this snapshot.
With just five rows of data, coverage is limited to a single measurement point per pollutant, so the dataset does not capture spatial variation across different neighborhoods or temporal changes beyond the most recent update. While the timestamps are current, the lack of multiple stations means that conditions elsewhere in Oakville could differ from what these values show. Users should keep in mind that this snapshot provides a concise but narrow view of the city’s air quality at one moment in time.
