Today in Forest
- Best time to air the house: around 8:00. The outdoor dew point drops to 8.6 °C; once warmed to 20 °C, that air holds only 48 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Washing outside: allow about 6 h, hanging it out between 11:00 and 17:00. Air at 76 % humidity, 15.2 °C and wind at 13.5 km/h: it will dry, but not quickly. How it is calculated
