Highlight every Warm Ocean on your Minecraft seed — Java 26.2 & Bedrock 1.26.30, any seed, free, no sign-up.
Quick answer: Warm Oceans are the warmest, most colourful seas in the game — turquoise water over coral reefs, sea pickles and swaying seagrass, with tropical fish and pufferfish darting through the coral. This finder highlights every Warm Ocean patch on your seed, free, Java & Bedrock.
Warm Oceans generate on the Overworld surface in the hottest ocean regions, typically off the coasts of deserts, jungles and other warm biomes. They are the only ocean with bright turquoise water and a coral-covered floor, and being shallow and warm they never contain an ocean monument.
Enter your seed and the map highlights every Warm Ocean — click any highlighted patch to read its coordinates. The finder runs the same world-generation maths Minecraft uses, so every patch of warm water is marked exactly on any seed and in either edition.
Warm Oceans are the only place coral reefs generate — brain, bubble, fire, horn and tube coral — alongside sea pickles you can harvest for light and seagrass for breeding turtles. Tropical fish and pufferfish dart between the coral, dolphins ride the surface, and the warm beaches that ring the bay are where turtles nest and lay their eggs.
Yes — both editions, Minecraft 26.2 on Java and 1.26.30 on Bedrock. Warm Oceans and their coral reefs generate the same way on both. The map highlights every patch on your seed, free and with no sign-up.
