Slow ocean swell at night, 8 hours
Seen from above, slow waves roll in over deep water, graded down to a moonlit night. Each swell is long and unhurried, with a soft hiss as the foam settles.

What it is
An aerial, top-down view of surf rolling over open water, colour-graded from bright turquoise to a dark, moonlit blue. The sound follows the picture: a slow rise as each swell builds, a gentle break, and a long, fizzing retreat as the foam settles. No two waves are the same length. Underneath sits a quiet bed of brown noise and a little wind, so there is never true silence between waves. The picture dims from 2:00 and is near-black from 5:00.
How to use it for sleep
Ocean sound has a built-in rhythm, and many people like to breathe with it for the first few minutes: breathe in as a wave builds, and out, slowly, as it pulls back. Let the breathing go after that. If you want a structured version, our free breathing pacer has slow breathing and 4-7-8 patterns you can try before you press play.
Waves move more than rain does, so try this one at a slightly lower volume than you would use for steady noise. If the swells feel too dramatic, a steady rain might suit you better.
Best for
People who find perfectly steady noise boring or harsh, anyone who sleeps best on holiday by the sea, and evenings when you want to slow your breathing before sleep. Our ocean sounds guide covers how waves compare with rain and noise.
Sound design note
Every sound here, the brown noise, the ocean and the wind, is generated by SleepBetter’s sound engine. There are no samples and no loops, so the waves never repeat in a pattern you can learn. We kept the breaks soft and rounded and pushed the energy into the long hiss of the retreat, because a sharp crash is the part of real surf most likely to wake a light sleeper.
How this was made
Audio: brown noise, ocean and wind generated by SleepBetter’s own sound engine (no samples, no loops). Footage: aerial top-down ocean surf over turquoise water, free stock under the Pexels License, colour-graded to night and looped by SleepBetter. No AI-generated picture or voice.
