Today in Colchester
- Airing the house between 8:00 and 11:00 is still the least bad option: a dew point of 10.2 °C means 53 % humidity once the air is warmed to 20 °C, barely better than the 50 % of a typical home. Five to ten minutes of through-draught is enough. How it is calculated
- Washing outside: allow about 8 h, hanging it out between 8:00 and 16:00. Air at 78 % humidity, 14 °C and wind at 14.1 km/h: it will dry, but not quickly. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry, wind at 22 km/h, 14 °C at 8 pm. A lovely evening. How it is calculated
