Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 15°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.
Dew point is just 10°C — dry, fresh air. This is the kind of night where an open window does exactly what you want it to: brings in cool, comfortable air that helps your body maintain its natural overnight temperature drop.
The week ahead
Tonight will be the best night, tue the worst.
