World Climate Lab

World Climate Lab is a real-time planetary climate simulator. Build a world or bring your own, set its star, rotation, and atmosphere, then watch a complete climate system develop from physical first principles. Nothing here is hand-painted or faked. Winds, ocean currents, cloud bands, rainfall, and ice form because the physics says they must.

Bring your own world, or build one here

Import your own terrain and discover the climate it would truly have, or shape a world from scratch in the built-in topography editor. Raise mountain ranges, carve oceans, and position continents, then let the simulation reveal the winds, rains, and temperature your world produces. For worldbuilders, this is the answer to a question maps alone can never settle: what would the weather actually be?

Build a world, then watch it breathe

Adjust a planet's spin and watch its weather reorganise in real time. Slow a world's rotation and see its circulation widen into vast climate bands. Lock it to its star and watch a permanent storm ring form along the line between endless day and endless night. Thicken the atmosphere, move the oceans, change the sunlight, and the whole system responds.

Terraform real worlds

Take Venus from a crushing greenhouse to a temperate world with oceans and weather. Warm a frozen Mars until rivers run. World Climate Lab models real planetary bodies, so you can test what these worlds might become.

Explore climates beyond Earth

Earth's familiar climate zones are only one possibility. World Climate Lab introduces a complete classification system for worlds that don't behave like ours, including fast rotators, slow rotators, and tidally locked planets where the rules of weather change entirely.

Real science, made visible

Every world is calculated from genuine atmospheric and physical models, then rendered with a planet shader that derives its colours, oceans, and atmospheric glow from the simulation itself. What you see is the physics, made beautiful.

Whether you are a worldbuilder testing a map you have drawn, a student of climate and physics, or someone who simply wants to watch a world come alive, World Climate Lab turns planetary science into something you can hold in your hands and play with.
