Today in Wellesley
- Best time to air the house: around 8:00. The outdoor dew point drops to 5 °C; once warmed to 20 °C, that air holds only 37 % 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 10:00 and 16:00. Air at 68 % humidity, 12.2 °C and wind at 5.6 km/h: it will dry, but not quickly. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry, wind at 11 km/h, 14 °C at 8 pm. A lovely evening. How it is calculated
