Highlight every Lukewarm Ocean patch on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Lukewarm Oceans are warm-water seas of teal-tinted water where tropical fish and dolphins gather, ringing the warm oceans but without the coral reef floor. Half of worlds have one within 750 blocks of the world centre. This finder highlights every Lukewarm Ocean patch on your seed, free, Java & Bedrock.
Lukewarm Oceans generate on the Overworld surface in warm regions, forming a broad band between the hottest warm oceans and the temperate normal ocean. The water is teal-tinted and warm enough for tropical fish, but unlike a warm ocean the sandy floor has no coral reef — just seagrass and kelp.
Often around 1,000 blocks. Across 200 random worlds, half had a Lukewarm Ocean within 750 blocks of the world centre (0, 0), and 9 in 10 had one within 2,200. Enter your seed above and click any highlighted patch to read its coordinates, then sail there by boat.

Measured with this finder on 200 random worlds, from the centre of the world (0, 0). A seed puts its biomes in the same places on Java and Bedrock, so one column covers both. Distances are rounded.
Lukewarm Oceans hold tropical fish and pufferfish like a warm ocean, but also cod, with playful dolphins riding the surface and squid and drowned below. Sandstone warm ocean ruins sit on the floor with their loot chests and treasure maps, making lukewarm seas a handy source of tropical fish for an aquarium without travelling all the way to a coral reef.
