- Garden: barely 0 mm of rain in 48 h against a need of about 11.3 mm. Water tomorrow, between 5:00 and 8:00, while it is cool: allow about 11 L/m². How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry, wind at 8 km/h, 16 °C at 8 pm, but the air drops below 16 °C from 21:00. Bring a jumper. How it is calculated
- Starry sky between 22:00 and 5:00: 0 % average cloud cover tonight, 7 h of clear sky in a row, moon at 14 % (waning crescent). A good night to look up. How it is calculated
