Weather



Weather was announced at April 7th 2011 and added in the 1.5 update, which was released on April 19th 2011. The type of weather can depend on the biome; arctic biomes can get snow, others get rain, and deserts get no precipitation whatsoever. Weather is very rare though and does not occur often. Rain makes the sky darker, blocks out the sun, stars, and moon and makes Wolves wetter. It also causes crops to grow and will put out fires (except burning netherrack), but it will not cause lava to turn into cobblestone or obsidian. Rain can also make puddles in small holes in the ground. When snowing, ice will grow back and snow will cover the ground where it can reach. There are also occasional thunder and lightning during both rain and snow. Rain is a feature activated by pressing F5 in-game in Classic. You cannot have lightning in Classic.

Rain
In all biomes save Tundra and Desert rain will occasionally fall. Rain will water crop tiles and cause wolves and tamed wolves to become wet. In addition to this rain will create a light sound around you while it falls. Rain will fall straight through Glass blocks and water crops underneath it, and cause all the effects that rain does in all circumstances.

Snow
Snow will only fall in the Tundra biome and causes water that does not have a block above it to become ice, as well as covering all blocks in snow with the exception of Glass which it will not fall through.

Facts about Weather

 * Rain and snow will be a temporary and global occurrence.
 * Rain is a single moving sprite.
 * Water does not stop rain like a solid block.
 * You can't see the sun, moon and stars while it's raining, and days are light level 12 instead of 15.
 * Higher odds of catching fish while raining. It may fill small holes with water.
 * It will not solidify lava, but it does put out fires.
 * Wolves get wet in the rain and crops will get watered.
 * Ice and snow will regrow whilst snowing.
 * Rain will not put out netherrack fires.
 * Lightning sets fire to the ground upon hitting it, but that is immediately extinguished by the rain.
 * If Lightning strikes a pig, it will morph into a zombie pigman.
 * Thunderstorms are much darker than normal rain, at light level 7 or less. Notch has confirmed it will be dark enough to spawn aggressive monsters.
 * Rain prevents monsters from burning.
 * Rain does not put out torches.
 * Rain and snow will still fall even when above cloud level.

Bugs

 * Rain falls through glass, stairs, and water.
 * Occasionally, in an area with many biome changes, the rain will appear to fall onto snow whilst not melting it.

History
After 1.5's announcement, a preview video was also uploaded onto the TeamMojang YouTube channel showing weather and other future updates.
