Conditions Report, August 18, 2026

A measured account of weather, lake temperature, air quality, and birdsong at Aera Cabins on August 18, 2026.

Aug 18, 2026

August 18, 2026 was dry, with no recorded 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 14.7–28.1°C, a measured spread of 13.4°C, and averaged 20°C across the available observations. Relative humidity averaged 74%. Wind speeds averaged 2.6 km/h, while the strongest recorded gust reached 11.5 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 22.3°C and stayed between 21.6–23.8°C, a daily spread of 2.2°C. That range was narrower than the air-temperature range measured over the same date. The lake summary is based on 23 archived sensor snapshots.

The lakeshore air monitor recorded an average AQI of 36, with hourly values ranging from 19 to 53. Average fine particulate concentration was 8.8 µg/m³. The daily average remained within the Good AQI category. These figures summarize 23 archived readings and do not substitute a regional estimate for the measurements made at the property.

BirdWeather’s final rolling 24-hour snapshot contained 544 acoustic detections across 10 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. 15 bird snapshots were archived during this report period.

Period Highlights

  • 0 mm of rain recorded
  • Lake averaged 22.3°C
  • Average AQI 36
  • 10 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.
