Cold Sweat: Altitude
Cold Sweat: Altitude is a NeoForge addon for Cold Sweat that ties its temperature to height, so a mountain climb or an airship ride feels different from travelling at sea level.
What it does
The addon adds altitude-based temperature zones to Cold Sweat. Warm underground layers give way to temperate surface conditions, then cold mountains and a hazardous upper sky, with smooth gradients between the bands rather than abrupt jumps. Players get clear colour-coded feedback when they move between layers, and the same system gives modpack makers control over caves, mountains and the layers in between.
Wind exposure rises with height, making open-air travel in high-altitude areas more dangerous. Shelter can reduce that exposure on land or aboard a ship. The addon also keeps altitude, temperature and wind active for assembled ships in Create-based builds that fly. Cold Sweat's biome weather, thermal blocks, hearth insulation and other systems keep working alongside the altitude effects.
The addon depends on Cold Sweat and needs version 2.4.4 or newer of it. The mod is released under the MIT License and is open source. It runs on NeoForge for 1.21.1 only, and the environment is client and server, so the server and every player need it. Latest file: 0.8.1 for 1.21.1, released 2026-10-01.
Key features
Altitude temperature bands
Temperature shifts across height-based layers, from warm underground to a hazardous upper sky.
Gradual transitions
Temperature changes smoothly between adjacent altitude layers instead of jumping at a boundary.
Wind exposure
High-altitude open areas expose players to wind, and shelter reduces that exposure.
Windproof Lining sewing
Windproof Lining armour is made at the Sewing Table to prepare for exposed flights.
Colour-coded feedback
Players see colour-coded indicators when they move between altitude layers.

Cold Sweat: Altitude is a Cold Sweat addon that makes the world’s temperature change with height. It was designed with Create: Aeronautics in mind: a climb in an airship should feel different from travelling at sea level. As a ship rises, the air can become colder, more exposed, and eventually dangerous without the…
