Today in Merredin
- Very high UV index: 8.8 around 12:00. Stay in the shade between 9:00 and 17:00. Fair skin burns in about 23 minutes: avoid exposure, cover up and use SPF 50. How it is calculated
- Terrace and barbecue between 18:00 and 23:00: wind at 18 km/h, gusts up to 48 km/h. Lay the parasol flat and shelter the barbecue. How it is calculated
- Best time to air the house: between 20:00 and 22:00. The outdoor dew point drops to −1 °C; once warmed to 20 °C, that air holds only 24 % humidity, against 50 % in a typical home: opening the windows dries the house. How it is calculated

- Garden: barely 0 mm of rain in 48 h against a need of about 15.9 mm. Water tomorrow, between 5:00 and 8:00, while it is cool: allow about 16 L/m². How it is calculated
