Tonight's plan
Slightly warm and humid tonight — manageable with the right setup.
Windows
Open after 7am
Cooler air arrives later — wait for it, then open wide — there's a breeze which will clear the room quickly
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
Helpful if muggy
Humidity is the issue more than heat — airflow helps sweat evaporate
Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 18°C, tonight sits right in the zone where sleep research says most adults sleep best. Your body can regulate its temperature naturally without any intervention.
The dew point — 17°C — is the real problem tonight. High dew point means your sweat can't evaporate, which is your body's primary cooling mechanism. This is why humid heat feels worse than dry heat at the same temperature, and why a fan helps more than you'd expect.
The week ahead
Sat will be the best night, mon the worst.
