Today in St Helena
- Very high UV index: 8.2 around 14:00. 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
- Best time to air the house: between 12:00 and 15:00. The outdoor dew point drops to 5.8 °C; once warmed to 20 °C, that air holds only 39 % 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 °C and wind at 15.5 km/h: it will dry, but not quickly. How it is calculated
- Garden: 12.1 mm of rain expected within 48 h, against a need of 6.8 mm. No need to water, the rain will do it. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry, wind at 6 km/h, 13 °C at 8 pm. A lovely evening. How it is calculated
- Starry sky between 22:00 and 0:00: 23 % average cloud cover tonight, 2 h of clear sky in a row, moon at 14 % (waning crescent). A good night to look up. How it is calculated
