Conditions Report, September 2, 2026
A measured account of weather, lake temperature, air quality, and birdsong at Aera Cabins on September 2, 2026.
September 2, 2026 was damp, with 15.8 mm of rain. The on-property weather station captured 23 hourly snapshots during the local calendar day, providing the basis for the temperature, wind, humidity, and rainfall summaries below.
Air temperature ranged from 11.9–17.2°C, a measured spread of 5.3°C, and averaged 14.6°C across the available observations. Relative humidity averaged 88%. Wind speeds averaged 3.3 km/h, while the strongest recorded gust reached 14.8 km/h. Rainfall is reported as the station’s highest cumulative local-day reading rather than a sum of hourly snapshots.
Cowichan Lake’s surface temperature at the dock averaged 20.4°C and stayed between 19.3–20.6°C, a daily spread of 1.3°C. That range was narrower than the air-temperature range measured over the same date. The lake summary is based on 25 archived sensor snapshots.
The lakeshore air monitor recorded an average AQI of 7, with hourly values ranging from 1 to 14. Average fine particulate concentration was 1.6 µg/m³. The daily average remained within the Good AQI category. These figures summarize 25 archived readings and do not substitute a regional estimate for the measurements made at the property.
BirdWeather’s final rolling 24-hour snapshot contained 92 acoustic detections across 7 species, with Chestnut-backed Chickadee the most frequently detected species in that snapshot. The bird total is intentionally taken from the last snapshot of the day; adding the hourly rolling totals together would count the same detections repeatedly. 25 bird snapshots were archived during this report period.
Period Highlights
- 15.8 mm of rain recorded
- Lake averaged 20.4°C
- Average AQI 7
- 7 bird species in the final 24h snapshot
Methodology
Daily values summarize hourly snapshots stored from the on-property sensors in America/Vancouver time. Temperature, humidity, wind, AQI, and PM2.5 are arithmetic summaries of available snapshots; rain is the maximum cumulative local-day reading. Bird counts are the rolling 24-hour values in the final snapshot of the day, not a sum of hourly snapshots.
