Cooler, drier air outside — open windows tonight
Heating

Standard weight — tonight sits right in the comfortable range
Fan
Not needed
Cool enough without — save the electricity
Based on temperature, dew point, wind, and overnight cooling
Why this matters
13°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.
The week ahead
Mon will be the best night, sun the worst.
