Air quality today
The air quality in Vaughan today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).
A single valid measurement recorded a PM2.5 concentration of 12.4 µg/m³, and no PM10 value is available for this assessment. Data is shown via OpenAQ. 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 current station data listed for this city is focused on particulate matter (PM). Only two monitoring rows are available for Vaughan, and both report PM2.5 concentrations measured in micrograms per cubic metre. The newest reading was recorded on 2026-02-10 21:56 UTC, which falls within the “updated within three days” category, while the other row is older than three days.
PM2.5 values range from a low of 2.1 µg/m³ to a high of 12.4 µg/m³, with a median of 7.25 µg/m³ and the central 80 % of observations falling between roughly 3.13 and 11.37 µg/m³. Because only two rows contribute data, coverage is limited and may not capture spatial variations across Vaughan. The dataset’s freshness is modest—one recent entry and one older record—so conditions can differ by location and time beyond what these figures show.
