What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available from the OpenAQ network, and they come from two reporting rows representing two distinct monitoring locations. The most recent reading was recorded at 2026-02-10 22:00 UTC, and one of the two rows has been updated within the last three days, indicating that at least part of the dataset is fairly current while the other entry is older.

Across the available observations, PM2.5 concentrations span from a minimum of 0.0 µg/m³ to a maximum of 10.0 µg/m³, with a median value of 5.0 µg/m³ and the 10th‑percentile at 1.0 µg/m³ and the 90th‑percentile at 9.0 µg/m³. This modest range suggests limited variability in the recorded particulate levels during the sampled periods. Because only a single pollutant is tracked and coverage consists of just two stations, the picture of air quality in North Cowichan is narrow; conditions can differ across neighborhoods and times that are not captured by this sparse dataset.
