Biomes are part of what makes Minecraft the incredibly beautiful game that it is.
Each Minecraft biome has its own climate with specifically coded weather distinctions. Some are warm and dry, others are cold and wet and others are combinations of the many weather traits. Temperature is determined on a number scale, ranging from 2 (hottest) to -0.5 (coldest).
Interestingly, many of the coldest biomes are also quite rare to come by. Even more notably, there will be drastic changes regarding biomes and temperature implemented with the upcoming 1.18 update.
The Minecraft Caves & Cliffs update promised some major developments in biome generation, mostly affecting the cold mountainous area of Minecraft worlds. New biomes will be added, most of which will be amongst the coldest in the game. The temperature range will extend to -0.7, which is colder than any biome has ever been in Minecraft.
Until then, there are still plenty of biomes with cooler climates in Minecraft currently. The following is a list of the coldest biomes in the game as of now.
