What the data includes

The Oak Bay air‑quality feed draws from twelve recorded rows supplied by a single monitoring site at Glenlyon Norfolk School. The dataset contains six measured variables: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. For most of these pollutants the newest reading is from 2026‑02‑10 22:00 UTC, showing that the data are generally up‑to‑date within the last few days. The exception is PM10, whose latest entry dates to 2025‑01‑13 23:00 UTC, indicating a gap of more than a year for that specific metric.

Across the recent observations the concentrations are low and tightly clustered. PM1 values range from about 0.06 to 0.24 µg/m³ with a median near 0.15 µg/m³; PM2.5 spans 0.44 to 0.90 µg/m³ with a median of roughly 0.67 µg/m³. The particle count UM003 varies between 170 and 228 particles/cm³, centering on a median of about 199. Relative humidity stays within a narrow band of 51 % to 53 %, while temperature hovers around 14.3 °C, ranging only from 14.28 to 14.34 °C. These figures illustrate limited variability in the recent sample set.

Because the feed relies on a single station, spatial coverage across Oak Bay is limited; conditions can differ in other neighbourhoods or at times not captured by the most recent timestamps. The older PM10 record further highlights uneven temporal coverage among pollutants, so users should keep in mind that the snapshot reflects one location and may not represent city‑wide fluctuations.
