Today in Cumbalum
- Very high UV index: 9.1 around 13:00. Stay in the shade between 12:00 and 18:00. Fair skin burns in about 22 minutes: avoid exposure, cover up and use SPF 50. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: wind at 19 km/h, gusts up to 49 km/h. Lay the parasol flat and shelter the barbecue. How it is calculated
- Best time to air the house: around 13:00. The outdoor dew point drops to 3.7 °C; once warmed to 20 °C, that air holds only 34 % humidity, against 50 % in a typical home: opening the windows dries the house. The outdoor air stays damp enough for 4 days in a row to push indoor humidity above 60 %, the level at which dust mites thrive: keep an eye on rooms with no draught. How it is calculated
- Washing outside: around 12:00. With 18 % humidity, 32.8 °C and wind at 22.6 km/h, a load of cotton washing dries in about 1 h. How it is calculated
- Heat: up to 34.2 °C in the next three days (days at 30 °C or more over the next 14: 1). Night ventilation: open the windows between 17:00 and 11:00, as soon as the outside air drops below 26 °C, and close windows and shutters again in the morning. How it is calculated
- Garden: barely 0.1 mm of rain in 48 h against a need of about 11.8 mm. Water tomorrow, between 5:00 and 8:00, while it is cool: allow about 12 L/m². How it is calculated
- Starry sky between 22:00 and 5:00: 11 % 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
