- Best time to air the house: around 8:00. The outdoor dew point drops to 5.6 °C; once warmed to 20 °C, that air holds only 39 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Washing outside: allow about 7 h, hanging it out between 9:00 and 16:00. Air at 75 % humidity, 11 °C and wind at 16.9 km/h: it will dry, but not quickly. How it is calculated
