This page covers Cuba, using Havana (23.1° north, UTC minus 5 in January and UTC minus 4 in July) as the reference point. Daylight, climate and daily routines shape when people naturally feel sleepy and when they wake.
Cuba is hot and humid, and a summer power cut can leave a bedroom without a fan for hours at night. Use the sections below for the seasons, the clock, the bedroom and a simple routine.
Optimal Sleep Times for Cuba, 90 Minute Cycle Guide
Your alarm time determines your bedtime, not the other way around. The table below works backward from common wake up times to give you cycle aligned bedtimes based on complete 90 minute sleep cycles. Waking at a natural cycle boundary eliminates sleep inertia and delivers maximum alertness from the first minute.
| Wake Up Time | 5 Cycles, 7.5 hrs | 6 Cycles, 9 hrs | 4 Cycles, 6 hrs | Quality |
|---|---|---|---|---|
| 5:30 AM | 9:45 PM | 8:15 PM | 11:15 PM | Optimal |
| 6:00 AM | 10:15 PM | 8:45 PM | 11:45 PM | Optimal |
| 6:30 AM | 10:45 PM | 9:15 PM | 12:15 AM | Good |
| 7:00 AM | 11:15 PM | 9:45 PM | 12:45 AM | Good |
| 7:30 AM | 11:45 PM | 10:15 PM | 1:15 AM | Good |
| 8:00 AM | 12:15 AM | 10:45 PM | 1:45 AM | Good |
Five cycles, about 7.5 hours, is a sensible starting point for most adults in Cuba. Adjust by how you feel after a week, and keep the wake time steady.
Seasonal Sleep Guide, Cuba by Season
The reference city for Cuba, Havana, sits at about 23.1° north, where day length changes modestly between seasons, enough to shift when you feel sleepy by a few weeks of adjustment. Calculated from latitude, the longest day is about 13 h 35 min and the shortest about 10 h 45 min, a difference of about 2 h 50 min. These are astronomical day lengths from sunrise to sunset, so cloud, hills and buildings will change what you see. Other parts of Cuba sit at different latitudes, so the gap will be wider or narrower depending on where you live.
Your body clock uses light as its main timing signal, so the aim across the seasons is a steady wake time with morning light, not a different bedtime every month. Move bedtime by 15 to 30 minutes at a time if you need to shift it.
Weather and Sleep Quality in Cuba
The climate in Cuba is best described as hot and humid through the year. The live weather widget on this page shows the temperature, humidity and wind for the city tonight, which you can use to choose how to set up your bedroom. Many sleep organisations suggest a bedroom temperature of about 16 to 19°C, which is not always realistic, so aim for as cool and quiet as is practical.
The job at night is to keep the bedroom cool and the air moving. A ceiling fan or air conditioner left at a steady setting is usually easier to sleep with than a burst of very cold air that switches off after an hour. Light cotton bedding, a cool shower before bed and a glass of water within reach all help. During rainy spells check that closed windows are not trapping humid air.
Try this: Choose a fan or air conditioner with a timer or steady setting, and keep bedding light and dry. Check the widget before bed and change one thing at a time so you can tell what helps.

Circadian Science for Cuba, Latitude, Light and Sleep
At 23.1136° latitude, Cuba receives light signals that your brain's suprachiasmatic nucleus (SCN), the biological master clock, uses to synchronise your 24.2 hour internal clock to the 24 hour solar day. This synchronisation is the foundation of all sleep quality. When it is disrupted, by shift work, artificial light or irregular schedules, sleep architecture can suffer.
