Weekly Conditions Report, October 12, 2026 to October 18, 2026

This weekly report brings together seven completed local-day reports from October 12, 2026 through October 18, 2026. Across those daily summaries, mean air temperature was 12°C and the weather station recorded 8.3 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 10.1°C to 13.6°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 17.1°C at the dock over the seven daily reports. Daily average lake temperatures ranged from 16.8°C to 17.5°C, a spread of 0.7°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 18, with individual daily averages ranging from 4 to 23. Mean daily PM2.5 was 4.3 µg/m³. Every daily average included in the weekly calculation remained in the Good AQI category.

Final rolling 24-hour BirdWeather snapshots ranged from 363 to 1,103 detections and from 10 to 20 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.
