The most relaxing ocean games on PC are ABZU and Beyond Blue: short, calm dives with no danger and a lot of sea life. For a longer stay, Dave the Diver mixes diving with running a sushi bar, and Coral Island gives a farm sim a reef to heal. Subnautica is the big underwater world, but it is scary unless you play in Creative mode. We checked every game on October 29, 2026.

What makes an ocean game cozy
The sea can be the calmest place in a game or the scariest. A cozy ocean game keeps the wonder and drops the dread: bright water, curious fish, a slow pace and little or no danger. A few things help: no oxygen meter (or a generous one), sea life that ignores you or swims along with you, and light that stays bright even when you go deep. Music matters too. We sorted the picks below from the calmest to the least calm. The last two are here because people search for them, and we want you to know what you are getting.
If you would rather stay on top of the water, see cozy fishing games, relaxing boat games and best cozy sailing games.

- Best long game: Dave the Diver

Calm dives with no danger
ABZU
Who it is for: anyone who wants one quiet evening under the sea.
You are a diver who swims through bright reefs, kelp forests and deep trenches, with schools of fish, whales and turtles all around you. There are no words, no enemies and no oxygen meter. You can sit on meditation spots and just watch the fish swim by. The music is lovely.
It is short, about two hours, and the story is vague by design. A few later parts are darker.
Developer: Giant Squid | Year: 2016 | Platforms: PC, PS4, Switch, Xbox One | Length: about 2 hours (HowLongToBeat) | Steam Deck: Verified | Steam page
Beyond Blue
Who it is for: nature lovers who want to learn while they swim.
You play Mirai, a deep-sea explorer who studies a pod of sperm whales and the life around them. You scan animals, tag them and learn real facts. Short films about the real ocean unlock as you play. There is no combat.
It is short, and the story and voice acting are simple. Some players wish there was more to do between the dives.
Developer: E-Line Media | Year: 2020 | Platforms: PC, PS4, Xbox One, Switch | Length: about 2.5 hours for the main story (HowLongToBeat) | Steam Deck: Verified | Steam page
Under the Waves
Who it is for: players who want a slow, sad story in a quiet place.
It is the 1970s, and you are Stan, a diver who works alone on the floor of the North Sea. You explore wrecks and do repair jobs, and you face the grief that sent him there. There is no combat, and you get around in a small submarine.
It is a story about loss, so it is heavy. On Steam Deck it is marked Unsupported, so play it on a PC.
Developer: Parallel Studio | Year: 2023 | Platforms: PC, PS4, PS5, Xbox | Length: about 7.5 hours for the main story (HowLongToBeat) | Steam Deck: Unsupported | Steam page
A life on the water
Dave the Diver
Who it is for: players who want a long, funny game with diving at its heart.
By day, you dive into the Blue Hole to catch fish. By night, you serve them at a sushi bar and set the menu. The sea changes as you dive, and there is a big cast of odd characters. It is very charming and has a lot to do.
It has an oxygen meter, harpoon fights with sharks, and boss battles. Most players still find it relaxing, but it is not danger-free.
Developer: MINTROCKET | Year: 2023 | Platforms: PC, Mac, Switch, PS4, PS5, Xbox | Length: about 25 hours for the main story (HowLongToBeat) | Steam Deck: Verified | Steam page
Coral Island
Who it is for: farm sim fans who want the ocean in their week.
Coral Island is a tropical farm life sim, but its ocean is a big part of it. After about a week you unlock diving. The reef starts covered in trash. You clear it, heal the coral and open deeper parts of the reef, with new sea life and finds as you go. Artifacts from the dives can go to the town museum.
It is a long farm game first, so the diving is one part of many. Its mines have monsters. For more like it, see games like Stardew Valley.
Developer: Stairway Games | Year: 2023 | Platforms: PC, PS5, Xbox Series X|S | Length: about 56.5 hours for the main story (HowLongToBeat) | Steam Deck: Verified | Steam page
Wavetale
Who it is for: players who want speed and sunshine on the sea.
You play Sigrid, who runs and surfs across the waves around a flooded island town. You help the townsfolk and find out what happened to the sea. Gliding across the water feels great.
It has some light combat against dark creatures, and it is short. For more drowned towns, see games set in a flooded world.
Developer: Thunderful Development | Year: 2022 | Platforms: PC, Switch, PS4, PS5, Xbox | Length: about 4 hours (HowLongToBeat) | Steam Deck: Playable | Steam page
A Short Sail
Who it is for: players who want to sail, snorkel and fish on a calm sea.
A Short Sail is a cozy sailing game where you are a little tabby cat with a sailboat. You deliver mail between little islands, fish by day and by night, and make friends. You can get a snorkel and swim over reefs and old ruins under the sea. Different fish bite in different waters and at different hours, and a few are rare shiny ones. Rain and storms roll in over the sea.
There are no timers. There is no fighting on foot, only gentle sea battles against storms and living waves. You can play alone or online with friends. The full game is coming to Steam and itch.io in Q1 2027, and you can play the free demo at play.ashortsail.com in your browser.

Big, but not always calm
Subnautica
Who it is for: explorers who want a huge alien ocean and can handle a scare.
You crash on an ocean planet and must survive. You dive, gather, build bases and submarines, and slowly learn the planet’s secrets. The reefs near your start are beautiful. In Creative mode, the survival needs are gone, so you can build and explore at your own pace.
Even in Creative mode, the deep water is dark, and large creatures can scare you. Many players call it a horror game at night. A sequel, Subnautica 2, came out in Early Access in May 2026.
Developer: Unknown Worlds Entertainment | Year: 2018 | Platforms: PC, Mac, PS4, PS5, Xbox, Switch | Length: about 29.5 hours for the main story (HowLongToBeat) | Steam Deck: Verified | Steam page
Watch out
- Endless Ocean Luminous: a calm diving game, but it is on Nintendo Switch only, not on PC.
- Dredge: a fishing boat game with no fighting, but sea monsters attack your boat at night and the mood is horror. See cozy games like Dredge for gentler picks.

Questions

ABZU. You swim with whales, fish and turtles through bright reefs and dark trenches, with no enemies and no oxygen meter. It takes about 2 hours.

Is Dave the Diver cozy?
Partly. Running the sushi bar and the bright dives feel cozy, but there is an oxygen meter, some fights with sharks and boss battles. Most players still call it relaxing.
Are there ocean games with no combat?
Yes. ABZU, Beyond Blue and Under the Waves have no combat. Coral Island has diving with no fights, though its mines have monsters.
Is Endless Ocean on PC?
No. Endless Ocean Luminous is on Nintendo Switch only. ABZU and Beyond Blue are the closest calm diving games on PC.
