Tonight's plan
A touch warm tonight, but nothing a light sheet won't fix.
Windows
Open
Cooler, drier air outside — open windows tonight
Heating
Off
Warm enough — heating would make it harder to sleep, not easier
Bedding
Light duvet or top sheet
Enough to feel covered, light enough to not trap heat
Fan
Not needed
Cool enough without — save the electricity
Based on temperature, dew point, wind, and overnight cooling
Why this matters
20°C is above the ideal 16–18°C range, but not dramatically. Most people will still fall asleep — it's staying asleep through the early hours that becomes harder, because your body can't complete its natural cooling cycle.
The week ahead
Mon will be the best night, tonight the worst.
