How weather affects sleep
Your body temperature drops as you fall asleep, and a bedroom that is too warm or too humid can make that harder. A room that is too cold can wake you in the early hours. Most people sleep best in a room that feels comfortably cool, with bedding they can adjust. The best setting differs from person to person, so test small changes over a week.
Weather also changes daylight, which shifts your body clock. Long summer evenings can push bedtime later and short winter mornings can make waking harder. See the hot weather sleep guide and the sleep hygiene checklist.

Frequently asked questions
Where does the weather data come from?
It comes from Open Meteo and loads in your browser when you choose a city.
What temperature is best for sleeping?
There is no single number. Many people prefer a cool room and adjustable bedding, so try small changes over a week.
Does humidity affect sleep?
High humidity makes it harder to lose heat, so many people feel warm and sleep lightly.
Why does the weather page not show my city?
The list covers the cities on this site. Choose the nearest one.
Is 8 hours too much sleep?
Eight hours sits inside the normal range. If you regularly need 10 or more hours and still feel unrefreshed, mention it to a doctor, because it can be linked with health conditions, medicines or poor quality sleep.
Does a consistent sleep schedule really matter?
Yes. A regular sleep and wake time supports your body clock, which can make it easier to fall asleep and wake up. Large gaps between weekday and weekend times can leave you feeling jet lagged on Monday.
Will waking at the end of a cycle remove morning grogginess?
It can help some people, because waking from light sleep is usually easier than waking from deep sleep. The effect is not guaranteed. Grogginess, known as sleep inertia, usually fades within 15 to 30 minutes and also depends on how much sleep you had and when you wake in your body clock.
How many hours of sleep does an adult really need?
The American Academy of Sleep Medicine and Sleep Research Society recommend at least 7 hours a night for adults. The National Sleep Foundation suggests 7 to 9 hours for most adults and 7 to 8 hours for people 65 and older. Some people need more, and you can judge your own need by how you feel on days you are not sleep deprived.
