Today in Willunga
- 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 12:00 and 15:00. The outdoor dew point drops to 6.5 °C; once warmed to 20 °C, that air holds only 41 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated
- Washing outside: allow about 6 h, hanging it out between 12:00 and 18:00. Air at 54 % humidity, 15.7 °C and wind at 11.8 km/h: it will dry, but not quickly. How it is calculated
- Garden: barely 0.1 mm of rain in 48 h against a need of about 8.2 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, wind at 4 km/h, 12 °C at 8 pm. A lovely evening. How it is calculated
