Weather



Weather in Minecraft consists of occasional precipitation and storms that are temporary but global.

Behavior


The type of weather that occurs depends on several variable factors, including the temperature of the current biome, and the altitude in which it occurs.

Players who have cheats enabled can change the current weather if they wish, by entering one of the following commands:  or, and  to clear the inclement weather. The  parameter is the duration of the weather in seconds. also switches to inclement weather, or vice versa.

Weather changing can be toggled on or off using the command. When is set to, the weather does not change indefinitely, unless altered using the  command.

Effects
Inclement weather reduces the sky light level, depending on the severity of the storm. Because of this, villagers return to their homes until the storm passes.

The sky itself darkens, to the point where celestial bodies (including the sun, moon, and stars) are no longer visible. The clouds darken depending on the severity of the weather; note that the clouds themselves do not precipitate. Although the sun is not visible during rain, the glow associated with sunrise and sunset is still visible.

Rain
Rain occurs only in biomes with a temperature of 0.15–0.95. Rainstorms reduce the light level to 12 in full daylight.

Rain extinguishes fires (including flaming arrows ). However, it does not extinguish fires on netherrack, and it does not solidify lava. Mobs that are on fire are extinguished on contact with rain; this prevents skeletons and zombies from burning during the day. On the contrary, endermen and snow golems may die due to their weakness to water. Endermen teleport randomly until they find a dry place. Blazes and striders that are brought into the Overworld take damage and eventually die from being in contact with rain.



Other interesting effects caused by rain:


 * Fish are more abundant during rain.
 * Wolves shake themselves dry if they are not moving (certain versions only).
 * Farmland becomes hydrated if it isn't already.
 * Rain fills up cauldrons with water, albeit slowly.

Rain particles make noise when they hit a block, and this noise can be heard at any point within 16 blocks. These particles (along with the associated sound) can be disabled by setting Particles to "Minimal" in the Video Settings menu.

Snow


Snowfall occurs only in biomes with a temperature less than 0.15, or above a sufficient altitude. Like rainstorms, snowfall reduces the light level to 12 in full daylight.

As it snows, snow layers regenerate over all non-transparent blocks. $$, these snow layers accumulate and grow over time. Snow does not cover transparent blocks.

Note that any entities on fire are not extinguished upon contact with snow.

Thunderstorm
Thunderstorms may occur in any biome. They reduces the internal sky light level. At noon the internal sky light level at surface is only 10. However, in mob spawning system, the light level from the sky is treated as if it were 5, allowing hostile mobs to spawn at any time of the day.

Lightning
Lightning occurs frequently during thunderstorms, if there is rain. It strikes randomly, creating fires where it strikes, igniting any nearby flammable materials, but the rain usually puts the fire out before it can spread. Note that lightning can strike only blocks that are exposed to the rain. Lightning does not occur naturally in biomes that are too hot or dry to have rain or so cold that it snows instead of rains, but can still be summoned with a channeling trident.

Lightning deals damage to entities on normal difficulty, not including the damage done by the fire it causes. It turns creepers into charged creepers, villagers into witches, pigs into zombified piglins, and mooshrooms into their brown variants.

Lightning may randomly spawn a "skeleton trap" skeletal horse, with a chance of 3.75–7.5% on Easy, 7.5–20% on Normal, and 11.25–33.75% on Hard, depending on the regional difficulty.

Thunder is a sound that occurs every time lightning strikes. It can be heard by the player up to 160,000 blocks away from the position of the lightning strike. Thunder is heard instantly, regardless the player's distance from the lightning strike itself.

Lightning may be manually summoned with the command. While it is summoned as an entity, it cannot be referred to by commands or selectors.

If the player throws a trident enchanted with channeling during a thunderstorm, it summons a lightning bolt at the thrown area.

Trivia



 * Rain and snow still falls above the clouds. Notch's explanation is that the gray above the clouds during a storm is “another layer of clouds” and the origin of the rain.
 * Rain and snow are both considered the same weather effect by the game. This explains why there is no command.
 * Rain and snow actually fall one block into the void (Layer -1). This can be seen in Creative Mode by floating in the Void. Note that no particles are emitted from the rain, due to the absence of a block below it for it to fall on.
 * Lightning does not have an image file associated with it. Thus, it is coded directly into the game engine, allowing for dynamic, realistic lightning.
