Today in Carstairs
- No washing outside today: the air is too cold or too damp to dry anything before evening (maximum drying power of 12.6 hPa per hour). How it is calculated
- Hard frost between 6:00 and 10:00: −5 °C around 6:00. Protect pots, pipes and outdoor taps; fleece is not enough for the most tender plants, so bring them indoors. How it is calculated
- Best time to air the house: between 7:00 and 9:00. The outdoor dew point drops to −11.7 °C; once warmed to 20 °C, that air holds only 11 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Terrace between 18:00 and 23:00: 1 °C at 8 pm. Too cold to eat outside; the barbecue will have to wait. How it is calculated
