Weekly Conditions Report, October 5, 2026 to October 11, 2026

This weekly report brings together seven completed local-day reports from October 5, 2026 through October 11, 2026. Across those daily summaries, mean air temperature was 13.3°C and the weather station recorded 14.4 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 9.4°C to 16.1°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 17.8°C at the dock over the seven daily reports. Daily average lake temperatures ranged from 17.5°C to 17.9°C, a spread of 0.4°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 16, with individual daily averages ranging from 14 to 23. Mean daily PM2.5 was 3.9 µg/m³. Every daily average included in the weekly calculation remained in the Good AQI category.

Final rolling 24-hour BirdWeather snapshots ranged from 105 to 705 detections and from 6 to 17 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.
