Today in Black Diamond
- No washing outside today: the air is too cold or too damp to dry anything before evening (maximum drying power of 11.9 hPa per hour). How it is calculated
- Best time to air the house: around 9:00. The outdoor dew point drops to −12 °C; once warmed to 20 °C, that air holds only 10 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Frost between 6:00 and 10:00: low of −1.5 °C around 8:00, with 4 h below freezing. Bring in or cover tender plants (horticultural fleece) and empty the watering cans. How it is calculated
- Terrace between 18:00 and 23:00: 0 °C at 8 pm. Too cold to eat outside; the barbecue will have to wait. How it is calculated
