Today in Jamestown
- Very high UV index: 8.8 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

- Washing outside: between 13:00 and 16:00. With 41 % humidity, 19.1 °C and wind at 9.3 km/h, a load of cotton washing dries in about 3 h. How it is calculated
- Garden: barely 0 mm of rain in 48 h against a need of about 10.8 mm. Water tomorrow, between 6:00 and 9:00, while it is cool: allow about 11 L/m². How it is calculated
- Terrace and barbecue between 18:00 and 23:00: dry, wind at 9 km/h, 14 °C at 8 pm. A lovely evening. How it is calculated
- Starry sky between 22:00 and 2:00: 12 % average cloud cover tonight, 4 h of clear sky in a row, moon at 14 % (waning crescent). A good night to look up. How it is calculated
