Updated for Java Edition 26.3 (October 2026).
The ocean is the Overworld’s plain, temperate sea: medium-blue water over a floor of sand, gravel and clay, with kelp, seagrass, cod and dolphins. It is one of nine ocean biomes and the most common of them. In our sample of 300 Java 26.3 seeds it covered 6.9% of the surface, and 77% of seeds had one within 1,000 blocks of spawn.
| Dimension | Overworld |
|---|---|
| Where it generates | Temperate coastal water between the beach and the deep ocean |
| How common | 6.9% of the surface in our sample (about 1 block in 15); all ocean types together 30% |
| Distance from spawn | Median 559 blocks; within 1,000 blocks in 77% of seeds, within 2,000 in 98% (our sample) |
| Mobs | Cod, squid, dolphins, nautiluses, drowned; glow squid in dark water underground |
| Notable blocks | Kelp, seagrass, sand, gravel and clay on the floor |
| Structures | Cold ocean ruins, shipwrecks, ocean ruined portals; underground mineshafts and trial chambers. No ocean monuments. |
| Climate | Temperature 0.5, downfall 0.5 |

All nine ocean types compared
Minecraft splits the sea by temperature (warm, lukewarm, normal, cold, frozen) and by depth. Each type except warm has a deep version, and only the deep ones get ocean monuments. In our sample of 300 Java 26.3 seeds, about 30% of the surface was ocean of some kind. This table shows how common each type was and what sets it apart.
| Ocean type | How common (our sample) | Median distance from spawn (our sample) | What sets it apart |
|---|---|---|---|
| Ocean | 6.9% | 559 blocks | Cod, dolphins, kelp; cold ocean ruins |
| Lukewarm ocean | 4.6% | 970 blocks | Tropical fish and pufferfish as well as cod; warm ocean ruins; no coral |
| Cold ocean | 4.4% | 845 blocks | Salmon and cod; no dolphins |
| Deep ocean | 3.7% | 888 blocks | Ocean monuments; same fish as the ocean |
| Deep lukewarm ocean | 2.4% | 1,361 blocks | Ocean monuments and warm ocean ruins |
| Deep cold ocean | 2.3% | 1,166 blocks | Ocean monuments; salmon and cod |
| Frozen ocean | 2.2% | 1,701 blocks | Icebergs of packed and blue ice, polar bears, salmon; no kelp |
| Warm ocean | 2.1% | 2,361 blocks | Coral reefs and sea pickles; tropical fish and pufferfish, no cod or kelp; no deep version |
| Deep frozen ocean | 1.2% | 2,086 blocks | Icebergs, polar bears and ocean monuments |
The water colour tells you where you are. It turns lighter and more turquoise toward the warm ocean, and darker, with a purple tint, toward the frozen ocean. Every ocean type has shipwrecks, nautiluses and drowned. Warm ocean ruins (sandstone) belong to the warm, lukewarm and deep lukewarm oceans; every other type, the plain ocean included, gets cold ocean ruins made of stone bricks.
How to find an ocean
You will rarely have to: the median distance from spawn in our sample was 559 blocks, and 98% of seeds had an ocean within 2,000 blocks. In our sample, 31% of an ocean’s edge touched deep ocean, 21% beach, 9% stony shore, and about 6% each river and forest. So the regular ocean is usually the band of water just off a temperate beach. Head straight out from the shore and the floor drops away into deep ocean, which is where monuments are.
These three Java 26.3 seeds put an ocean close to world spawn. Each coordinate is inside the ocean biome, checked at block level.
| Seed | Ocean at | From spawn | Map |

X -510, Z -310 | 595 blocks | Open on the map |
With cheats on, /locate biome minecraft:ocean finds the nearest one; swap in minecraft:lukewarm_ocean, minecraft:deep_cold_ocean and so on for the other types. The biome finder shows every ocean type around spawn for any seed. These are Java seeds; the same number on Bedrock gives a different world.
What lives in the ocean
Cod are the only fish that spawn in the regular ocean, along with squid and small groups of dolphins. Feed a dolphin raw cod and it swims toward the nearest shipwreck, ocean ruin or buried treasure; swimming next to one gives you Dolphin’s Grace. Since Java 1.21.11 the nautilus spawns here too. It is tamed with pufferfish, which don’t spawn in this biome, so catch some in a lukewarm or warm ocean first.
The drowned is the hostile mob of the open sea. Some carry a trident, which they throw. Salmon, tropical fish and turtles do not spawn in the regular ocean; turtles nest on the beaches next to it.
Structures and loot
Cold ocean ruins, small piles of stone and mossy stone bricks, sit on the floor and can hold loot chests and suspicious gravel. Shipwrecks are common. Their map chest holds a buried treasure map, which leads to a buried treasure chest on a nearby beach with a heart of the sea inside. Ocean-style ruined portals can turn up on the sea floor too.
Ocean monuments never generate in the regular ocean, only in the four deep types. If you are after sponges and prismarine, follow the ocean out into deep water, or use our ocean monument finder.
What changed in 2025-26
In Wilderness Bound (Java 26.3, September 2026), explorer maps became their own items. The Ocean Monument Explorer Map is now called the Ocean Monument Map.
In Mounts of Mayhem (Java 1.21.11, December 2025), the nautilus, a neutral aquatic mob you can tame with pufferfish and ride, started spawning in all ocean biomes, the regular ocean included.

How we measured
The numbers on this page come from our own seed map engine, running Java Edition 26.3 world generation. We generated 300 random seeds and sampled every 16th block across a 10,240 by 10,240 block square centered on each world’s spawn. “How common” is each ocean type’s share of those samples; “distance from spawn” is how far the nearest sample of that type was. The seeds above were picked from the same run, and each coordinate was re-checked at block level.
