Today in Lake Cowichan
- Terrace and barbecue between 18:00 and 23:00: rain likely (0.4 mm, up to 17 % chance). Have some shelter or a plan B ready. How it is calculated
- Best time to air the house: between 19:00 and 22:00. The outdoor dew point drops to −3.9 °C; once warmed to 20 °C, that air holds only 20 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Washing outside: only just possible. Even hung out between 9:00 and 19:00, it will take about 10 h; bring it in before the air turns cooler. How it is calculated
