Northbound – Latitude-Based Climate Zones

Vanilla Minecraft scatters biomes unpredictably, often breaking the sense of a logical, travelable world. Northbound solves this by reorganizing overworld generation around a realistic latitudinal climate gradient. Instead of random noise, biomes are placed in bands: colder biomes appear as you journey north from the world origin, and warmer biomes appear as you move south. This gives every world a familiar geographic logic—perfect for players who want exploration to feel guided by climate rather than chance.

Upon creating a new world, you will most often spawn in a temperate zone (plains, forests) and find yourself in the “northern hemisphere.” Heading north gradually shifts the landscape through cold taigas and dark forests before reaching the snowy polar cap. Traveling south leads first through arid deserts and badlands, then into lush tropical jungles and mangrove swamps. The pack defines five distinct zones—Tropical, Arid, Temperate, Cold, Polar—each populated with appropriate vanilla biomes, creating a predictable east–west banding that makes navigation by the sun meaningful.

This datapack is aimed at builders seeking geographically coherent backdrops, survivalists who enjoy climate progression, and mapmakers who need reliable biome placement without command block trickery. It also provides an educational look at how latitude shapes real-world ecosystems, all within the default game.

• Latitude-driven biome layout – Biomes follow a realistic north–south temperature gradient instead of random noise.
• Five climate zones – Tropical, Arid, Temperate, Cold, and Polar bands each contain appropriate biomes (jungles, deserts, taigas, etc.).
• Predictable spawn logic – You start in the northern hemisphere, usually in temperate biomes; cold lies to the north, warmth to the south.
• Works with vanilla structures – Villages, temples, and other generated structures still appear in their native biomes, now positioned in a logical climate context.
• Transparent limitations – A very large ocean near spawn can occasionally shift your starting latitude, but the north=cold / south=warm rule always holds.

Requires Minecraft Java Edition 1.20 or later. You must create a fresh world with this datapack enabled; it will not alter pre-existing terrain. Because it overhauls the biome placement algorithm, Northbound is incompatible with other world generation datapacks that modify the same systems.
