Weekly Conditions Report, August 31, 2026 to September 6, 2026

This weekly report brings together seven completed local-day reports from August 31, 2026 through September 6, 2026. Across those daily summaries, mean air temperature was 15.8°C and the weather station recorded 35.9 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 13.8°C to 17.7°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 20.4°C at the dock over the seven daily reports. Daily average lake temperatures ranged from 20.2°C to 20.7°C, a spread of 0.5°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 12, with individual daily averages ranging from 7 to 18. Mean daily PM2.5 was 2.8 µg/m³. Every daily average included in the weekly calculation remained in the Good AQI category.

Final rolling 24-hour BirdWeather snapshots ranged from 70 to 209 detections and from 6 to 10 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.
