Today in Tournai
- No washing outside today: rain, or a risk of rain, covers the hours when it could dry. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: rain likely (0 mm, up to 90 % chance). Have some shelter or a plan B ready. How it is calculated
- Best time to air the house: tomorrow, around 13:00. The outdoor dew point drops to 2.7 °C; once warmed to 20 °C, that air holds only 32 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Garden: 27.9 mm of rain expected within 48 h, against a need of 1 mm. No need to water, the rain will do it. How it is calculated
