The world’s sleep weather
Every country, colored by how its people slept. Where few have voted so far, we estimate from night-time internet activity.

Human web traffic (Cloudflare Radar) or Wikipedia reading between 2 and 5 am local time, compared with the same weekday over the past eight weeks. The percentage shows how much more or less there was than usual; the past year shows how rare that is. More traffic suggests more people awake.

Do we all sleep badly on the same nights?
Some mornings it feels like the whole world is tired. Weather, the moon, the news, a shared kind of stress: maybe our nights are more connected than we think. One tap a day, from everyone, everywhere, and we’ll find out.
Questions
What is Sleep Weather?
A daily, worldwide check-in. Every morning people tap how they slept, and the map shows how each country slept. We want to find out whether whole countries, or the whole world, sleep badly on the same nights.
Is it anonymous?
Yes. There’s no account and no tracking cookie. We read your country from your connection, but we never store your IP address. To stop double votes we keep a scrambled code for two days, then delete it.
How does the sleep forecast work?
It combines tonight’s temperature, humidity, wind, storms and weather fronts near you with air quality, pollen, the day of the week, holidays and night-time events, Ramadan, the moon, space weather and clock changes. Each factor shows how well studied it is. It’s an experiment: every morning the votes show whether it was right.
What is “night activity”?
How much people were online between 2 and 5 am local time: human web traffic measured by Cloudflare Radar in larger countries, Wikipedia reading elsewhere. Each night is compared with the same weekday over the previous eight weeks (100 = a normal night), and the past year shows how unusual it was. Above 100, more people than usual were awake.
What do you measure with?
Four things. Votes: what visitors say about their own night. Night-time internet activity in 65 countries, all traffic and phones separately: more people online between 2 and 5 am than usual suggests a worse night. Filters: nights with an internet outage are left out. And the conditions of the night that research ties to sleep (unusual heat, bad air, storms, a clock change, a free morning), which shift the estimate a little. Everything else that happened is shown as a possible explanation. Night-time searches (Google, YouTube) are collected but not used: on the history so far they did not move with the traffic, and only votes can tell which is right.
Why are some countries paler on the map?
Those are estimates. Until enough people from a country have voted, we estimate its night from how busy the internet was there between 2 and 5 am: a busier night than usual counts as worse sleep. Every vote pulls the color towards what people actually said: the estimate weighs as much as ten votes, so its share fades as more people vote.
Can I change my answer?
Yes. You can vote once a day and change your answer until midnight. Your vote counts for the day you woke up.
Is this medical advice?
No. Sleep Weather is for curiosity and fun. If you often sleep badly, talk to a doctor.
