Today in Balhannah
- Very high UV index: 8.7 around 13:00. Stay in the shade between 12:00 and 18:00. Fair skin burns in about 23 minutes: avoid exposure, cover up and use SPF 50. How it is calculated
- Best time to air the house: between 15:00 and 18:00. The outdoor dew point drops to 6.6 °C; once warmed to 20 °C, that air holds only 42 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Washing outside: allow about 5 h, hanging it out between 12:00 and 17:00. Air at 56 % humidity, 16.5 °C and wind at 9.5 km/h: it will dry, but not quickly. How it is calculated
- Garden: barely 0 mm of rain in 48 h against a need of about 8.4 mm. Water tomorrow, between 6:00 and 9:00, while it is cool: allow about 8 L/m². How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry but cool, 11 °C at 8 pm and wind at 7 km/h. Wrap up warm, or move indoors. How it is calculated
- Starry sky between 22:00 and 5:00: 10 % 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
