Today in Chimay
- 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 (3.1 mm, up to 100 % chance). Have some shelter or a plan B ready. How it is calculated
- Best time to air the house: tomorrow, between 12:00 and 14:00. The outdoor dew point drops to 1.4 °C; once warmed to 20 °C, that air holds only 29 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Garden: 51.8 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
