Weekly Conditions Report, August 24, 2026 to August 30, 2026

This weekly report brings together seven completed local-day reports from August 24, 2026 through August 30, 2026. Across those daily summaries, mean air temperature was 17.4°C and the weather station recorded 4.5 mm of cumulative daily rainfall. Each day remains independently bounded in America/Vancouver time before the weekly values are combined.

The rainfall total is the sum of each day’s highest cumulative local-day station reading, not a sum of hourly observations. Daily mean air temperatures ranged from 15°C to 20.3°C. This describes the variation among daily averages; the individual report pages retain each day’s measured minimum, maximum, wind, gust, humidity, and coverage details.

Cowichan Lake averaged 21.6°C at the dock over the seven daily reports. Daily average lake temperatures ranged from 20.8°C to 22.3°C, a spread of 1.5°C. The weekly lake figure is therefore a mean of daily sensor summaries rather than a claim that every moment of the week held the same temperature.

The mean daily AQI was 14, with individual daily averages ranging from 3 to 28. Mean daily PM2.5 was 3.4 µg/m³. Every daily average included in the weekly calculation remained in the Good AQI category.

Final rolling 24-hour BirdWeather snapshots ranged from 77 to 716 detections and from 8 to 13 species. These are comparisons among the seven final daily snapshots; the report does not add rolling detection totals together because doing so would repeatedly count overlapping detections.
