The air quality in Lake of Bays Township is classified as Good today. The primary pollutant identified is PM2.5 (fine particles).
Measurements recorded for this assessment show a PM2.5 concentration of 6.0 µg/m³, based on two valid observations collected 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
Lake of Bays Township’s OpenAQ feed currently includes measurements for ozone (O3) and fine particulate matter (PM2.5). The dataset is built from a very small number of sensor records – only two recent observations are available across both pollutants, all coming from the Dorset monitoring site. The most recent timestamp in the set is 2026-02-10 22:00 UTC, which means the newest data are just a few days old and fall within the “updated within 3 days” freshness category.
For ozone, values range from a low of 0.030 ppm to a high of 0.039 ppm, with a median of about 0.0345 ppm. The 10th percentile sits at 0.0309 ppm and the 90th percentile at roughly 0.0381 ppm, indicating that most recent readings cluster tightly within this narrow band. PM2.5 shows a broader spread: concentrations vary from 6.0 µg/m³ up to 13.0 µg/m³, with a median of 9.5 µg/m³. The lower decile is 6.7 µg/m³ and the upper decile reaches 12.3 µg/m³, suggesting more variability in particulate levels than for ozone.
Because only two rows are present and both originate from the same location, spatial coverage across Lake of Bays Township is limited. While the timestamps are recent, the paucity of stations means that conditions elsewhere in the township may differ from those recorded at Dorset. Users should keep in mind that the dataset provides a snapshot rather than a comprehensive picture of air quality throughout the entire area.
