Based on temperature, dew point, wind, and overnight cooling
Why this matters
8°C is cool — ideal for sleep depth. Research shows deeper slow-wave sleep in cooler bedrooms, as long as the room stays above about 16°C. If your bedroom drops below that, sleep quality starts to decline again.
Dew point is just 7°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, sun the worst.
