Today in Dalmeny
- Very high UV index: 8.2 around 13:00. Stay in the shade between 12:00 and 18:00. Fair skin burns in about 24 minutes: avoid exposure, cover up and use SPF 50. How it is calculated

- Washing outside: between 12:00 and 14:00. With 36 % humidity, 20.4 °C and wind at 21.8 km/h, a load of cotton washing dries in about 2 h. How it is calculated

- Terrace and barbecue between 18:00 and 23:00: dry, wind at 18 km/h, 17 °C at 8 pm, but the air drops below 16 °C from 22:00. Bring a jumper. How it is calculated
- Starry sky between 22:00 and 4:00: 9 % average cloud cover tonight, 6 h of clear sky in a row, moon at 14 % (waning crescent). A good night to look up. How it is calculated
