Going to bed for a 3:31 am alarm

  • Asleep by 6:16 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 7:46 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 9:16 pm — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 3:31 am

While you wait for the scheduled check at the Surf Life Saving station, a 3:31 am alarm can mark the moment without making you watch the clock continuously. There are 29 minutes until 4:00 am, enough time to finish a quiet equipment check or note any change in conditions while keeping the appointed time in mind.

During a station watch, another browser page may take over the screen while this alarm remains in the background. It should continue counting, but battery-saving settings can sometimes restrict background activity, so return to the alarm page shortly before 3:31 am and confirm that it is still active. Keep the browser open and the phone or computer awake: otherwise the Surf Life Saving station alarm may not sound when the scheduled check is due. Set the volume beforehand and avoid relying on a muted speaker.

Before the station check comes around in the dark, arrange the nearby light so you can respond without fumbling or flooding the room with glare. Leave a low lamp aimed toward the logbook or equipment area, and reduce screen brightness while you wait. At 3:31 am, that prepared pool of light will make the alarm easier to dismiss and the next task easier to see, while preserving night vision for looking outside.
