Weather

Weather is a game mechanic that was added in Update 0.12.1. It adds weather conditions into the game.

Clear
Most common weather type, was originally the default in-game. The sun is out and the sky is its regular blue.

Rain

 * Rain occurs in most biomes except dry and cold biomes, like Deserts and Ice Spike biomes
 * Extinguishes Fire (both on blocks and players/mobs)
 * Damages Endermen, Snow Golems, and Blazes

Snow

 * Only snows in snowy biomes, like taiga and in cold biomes such as Extreme Hills, above a certain height but below y=128.
 * Covers blocks with Snow Layers.
 * Version Exclusive: Snow has a gravitational effect (meaning if the block that is below it is broken, it will fall).
 * Version Exclusive: During snowfall, leaves in snowy biomes will get frosty.

Thunderstorms

 * Decreases the light level to 7, allowing hostile mobs to spawn during the day (other than in Roofed Forest biomes and in caves underground).
 * Causes lightning to fall, causing damage to be dealt to players and mobs.
 * Can also create Charged Creepers from Creepers, Zombie Pigmen from Pigs, and Witches from Villagers.
 * Usually very rare occuring.
 * Sleeping in a thunderstorm is possible.

Trivia

 * It is recommended that the player seeks shelter during a thunderstorm, so that they do not get struck by lightning.
 * Cauldrons have a chance of filling up when it is raining.
