Overview
Lukewarm ocean is the shallow warm-water ocean, with a sand floor, plentiful seagrass and enough life in it that it feels different from the grey cold oceans further out. Tropical fish, pufferfish, cod, squid and dolphins all spawn here, which covers food, the pufferfish for Water Breathing potions, and the fastest natural swimming aid in the game — swim beside a dolphin and Dolphin's Grace roughly triples your speed for as long as you stay close and for 5 seconds after. Warm-variant ocean ruins generate on the floor, built from sandstone rather than stone, with their own chests holding buried treasure maps, emeralds and gold. Sea pickles occasionally grow on the sand and give light underwater; a group of 4 gives light level 15 in air. What lukewarm ocean does not have is coral — coral reefs are strictly a warm ocean feature — and it is not deep enough for an ocean monument. Drowned spawn as they do in every ocean, and a small proportion carry tridents. It borders warm ocean on the hot side and ordinary ocean on the cool side, with beaches at the coast.
Pufferfish for Water Breathing, tropical fish for dyes and for feeding axolotls, dolphins for travel speed, warm ocean ruins for treasure maps, and sand and sea pickles from the floor.
Lukewarm Ocean is a temperate biome that generates in the Overworld. Its base temperature of 0.5 places it in the temperate band, which controls whether water freezes, whether it rains or snows, and which passive mobs are allowed to spawn there.
Weather reaches Lukewarm Ocean: it rains during storms, so crops grow and cauldrons fill on their own.
2 generated structures can appear here, among them Ocean Ruins and Shipwreck.
4 mobs name Lukewarm Ocean specifically among their spawn biomes: Cod, Dolphin, Pufferfish, and Tropical Fish.
Ocean biomes vary by temperature: warm oceans carry coral and tropical fish, cold and frozen ones do not. Every ocean can hold a shipwreck, a ruin or buried treasure, and the deep variants are where ocean monuments generate.
How to get it
Lukewarm ocean generates between warm and temperate ocean bands, usually off a jungle, desert or savanna coast. A dolphin fed 1 raw cod swims towards the nearest ruin or shipwreck, which saves a long search.
Tips
- 1 pufferfish plus an awkward potion brews 3 bottles of Water Breathing, which is enough for a whole monument run.
- Sea pickles spread with bone meal on coral blocks, so 1 pickle becomes a light farm if you bring a coral block home.
- Never hit a dolphin: every dolphin within 16 blocks turns hostile at once and they swim faster than you do.
- Tropical fish come in 22 named varieties; the bucket keeps the exact pattern, which is what makes aquariums worth building.
Climate and generation
Lukewarm Ocean has a base temperature of 0.5, which puts it in the temperate band. Temperature is not a thermometer reading — it is the single number that decides snow versus rain, whether water freezes over, and what colour the grass renders.
Above 0.15 water stays liquid and any precipitation falls as rain.
| Property | Value | What it changes |
|---|---|---|
| Temperature | 0.5 | Decides whether rain falls as snow, whether water freezes, and the grass and foliage tint. |
| Precipitation | Yes | Cauldrons fill on their own and farmland stays hydrated during a storm. |
| Dimension | Overworld | Sets which mobs, structures and ores can generate at all. |
| Grass and water tint | #7BA4FF | The colour the game applies to grass, leaves and water in this biome. |

Mobs in Lukewarm Ocean
Cod, Dolphin, Pufferfish, and Tropical Fish name Lukewarm Ocean specifically as a spawn biome, so this is where you go to find them.
On top of those, the mobs that spawn in open terrain anywhere in the Overworld can appear here too, given the right light level. Mobs that only come from a structure or a spawner — breezes from trial chambers, blazes from fortresses, evokers from mansions — are deliberately not in this list.

Structures found here
2 structures can generate in Lukewarm Ocean: Ocean Ruins and Shipwreck.
- Ocean Ruins — Scattered clusters of sunken buildings, in a sandstone warm-water variant and a stone cold-water variant.
- Shipwreck — A wrecked sailing ship, generated upright, capsized, or broken in two, on the sea floor or beached on the sand.
