* '''Effect:'''
Intense sunlight is called by the move {{m|Sunny Day}} and the ability {{a|Drought}}. It increases the power of {{type|Fire}} moves by 50%, and decreases the power of {{type|Water}} moves by the same amount. Despite its Fire-type affinity, many of its effects also benefit {{type|Grass}}s, activating and enhancing several abilities associated with them, including {{a|Chlorophyll}}, {{a|Flower Gift}}, {{a|Harvest}}, {{a|Leaf Guard}}, and {{a|Solar Power}}. It also allows {{m|Solar Beam}} to be used instantly, causes {{m|Moonlight}}, {{m|Synthesis}}, and {{m|Morning Sun}} to recover ⅔ of max {{stat|HP}}, and doubles stat increases when using {{m|Growth}}. On the other hand, it decreases the accuracy of {{m|Thunder}} and {{m|Hurricane}} to 50%. All Pokémon are immune to {{status|freeze|freezing}} while the sun is intense.

It also occurs in the most western areas of the [[Unova]] region during the [[Seasons|wintertime]]. This overworld condition does not result in an in-battle condition.
** Heavy snow: Snow falls more quickly and heavily, falling diagonally from one of the top corners of the screen (leaving the impression that it is being carried by strong winds), and sometimes appears to be mixed with hail. Found on {{rt|216|Sinnoh}}, [[Acuity Lakefront]] and sometimes in [[Icirrus City]] and {{rt|8|Unova}} during the Winter. In battle this overworld condition results in a hailstorm.
** Blizzard: Snow whips around, making it difficult to see. Found on {{rt|217|Sinnoh}}, and less often on {{rt|216|Sinnoh}}. In battle this overworld condition results in a hailstorm.
** {{DL|Easter egg|Diamond dust}}: Small ice crystals twinkle in the air. Found on certain special days in [[Snowpoint City]], [[Mt. Silver]] and [[Icirrus City]]. Diamond dust, however, does not have the same effect as other snowy conditions in battle and instead has no effect in battle.

Weather conditions (Japanese: てんき Weather) are mechanics of the Pokémon games, and have been included in every main series game since Generation II. The weather system was expanded on in Generation III, and again further expanded in Generation IV. In each generation, the weather has been determined either by the location of the battle or the Pokémon involved. Only one weather condition may be present at one time, and only the most recent weather condition will take effect.

Characteristics

In all generations since Generation II, some moves, such as Thunder and SolarBeam, take advantage of certain weather conditions and have increased power or accuracy. Other moves can directly cause or cease weather, such as Sunny Day and Defog. Beginning in Generation III, some Abilities have revolved around weather effects: the weather trio's Groudon and Kyogre's respective Abilities, Drought and Drizzle, can cause changes in the weather; while Rayquaza's Ability Air Lock neutralizes it.

Weather-utilization

Main article: Castform

One of the Pokémon introduced in Generation III was designed to take full advantage of the varying weather conditions. In a battle, where no weather effects are present, Castform is a Normal-type Pokémon. However, when any of the effects besides a sandstorm or Shadow Sky are applied, Castform's type and shape change to match the weather, due to its Ability, Forecast. Also, when it is leveled up, it learns a move called Weather Ball, which also changes type with the weather, doubling its power when any weather was in effect. Unlike Forecast, Weather Ball's type differs even in a sandstorm, becoming a Rock-type move, and Shadow Sky, becoming a ???-type move.

History

Generation II

In the Generation II games, three moves were introduced that could change the weather during a battle to alter the playing field slightly. These moves were Sunny Day, which caused intense sunlight for five rounds; Rain Dance, which caused heavy rain for five rounds; and Sandstorm, which caused a sandstorm. These three moves can change the course of a battle, with intense sun and heavy rain powering up Fire- and Water-type moves, respectively, and powering down the other; intense sun also allows a Pokémon to execute SolarBeam without requiring a turn to charge it first, and heavy rain causes Thunder to never miss the target. A sandstorm slightly damages any Pokémon that are not Rock-, Ground-, or Steel-type.

Although weather conditions were introduced in this generation, they could not be seen in the overworld until the next generation.

Generation III

The Generation III games introduced a new weather condition: hail. Hail is caused by the identically titled move Hail, which, like Sunny Day, Rain Dance, and Sandstorm before it, changes the weather for five turns. Hail, similar to sandstorm, slightly damages all Pokémon that are not Ice-type each turn.

The version mascots of Pokémon Ruby, Sapphire, and Emerald have weather-related Abilities. Ruby's Groudon's Drought causes intense sunlight until the battle ends or another weather effect takes its place; likewise, Sapphire's Kyogre's Drizzle causes heavy rain until the battle ends or another weather effect takes its place. Emerald's Rayquaza's Air Lock suppresses the effect of all weather conditions, but the weather itself continues. Psyduck and Golduck can also have the Ability Cloud Nine, which has the same effect as Air Lock.

During a specific part of the game, Groudon and Kyogre's weather effects can be seen out of battle, throughout the Hoenn region. Some routes are also naturally affected by the weather: Route 119 is often covered in rain; Route 111 has an area in which a sandstorm always blows. These field weather effects carry onto later games. A location in Hoenn, the Weather Institute, is dedicated to the study of weather. The Weather Institute is said to have created Castform, a Pokémon that changes with the weather.

Tyranitar has the Ability Sand Stream, which causes a sandstorm until the battle ends or another weather effect takes its place. Other Pokémon have Abilities that benefit from weather that is already in effect, such as Lotad's Rain Dish.

Generation IV

In the Generation IV games Pokémon Diamond, Pearl, Platinum, HeartGold, and SoulSilver, there are routes which are constantly affected by rain, sandstorm, or snow. A new weather condition was also introduced: fog. Unlike the other conditions, fog cannot be caused by a move; instead it appears in certain areas, and Defog can remove it.

A new Ability is introduced that acts as a counterpart to some of the Abilities introduced in Generation III. Snow Warning causes a hailstorm for the duration of the battle, in the same way as Drought, Drizzle and Sand Stream. Four held items were also introduced, which each correspond to a certain weather condition and will increase the duration of the weather condition, if caused by a move used by the holder, by three turns.

The move Hail now boosted the accuracy of Blizzard to 100%; The move Sandstorm now boosted the Special Defense of Rock-type Pokémon by 50%.

More interesting things introduced within Generation IV were other conditions that had nothing to do with the weather, but behaved similarly to the weather-activating moves. Like the weather conditions, these moves would affect all Pokémon on the field for five turns, and in various ways. For example, Gravity makes all Pokémon fall to the ground, enabling all Pokémon to be susceptible to things such as Ground-type moves, Spikes, Arena Trap, and others; decreases the evasion of all Pokémon by two stages; as well as disabling moves like Fly and Hi Jump Kick. Trick Room makes slower Pokémon attack first, and Tailwind doubles the Speed of the user's team for three turns.

Acid rain, a weather-related glitch, is present in HeartGold, SoulSilver, and Platinum, in which all weather conditions are present at once.

Generation V

Generation V introduced seasons, which can affect the occurrence of weather in certain cities and routes. For instance, in Driftveil City, hail and snow are present only during the winter, while rain is common during the spring and autumn. The Pokémon Thundurus and Tornadus cause a storm on the route they are on, which is treated as rain in battle. Despite still being present on some routes, fog is no longer present in battles and cannot be removed via Defog.

Also introduced were several new Abilities that make use of the weather. Sand Rush and Sand Force both benefit a Pokémon during a sandstorm, while Overcoat negates the damage taken in a hailstorm and sandstorm. With the addition of Hidden Abilities, many old Pokémon now have access to weather-related Abilities. Most notability, Drought and Drizzle, previously available only to Groudon and Kyogre, are now available to more Pokémon. Specifically, Vulpix and Ninetales now have access to Drought, while Politoed now has access to Drizzle.

Types of weather

There have been six different weather conditions that affect battling in the main series of Pokémon games, and all but one of them have effects in the overworld.

Intense sunlight

Main article: Intense sunlight
Icon from Black 2 and White 2

Intense sunlight is called by the move Sunny Day and the ability Drought. It increases the power of Fire-type moves by 50%, and decreases the power of Water-type moves by the same amount. Despite its Fire-type affinity, many of its effects also benefit Grass-types, activating and enhancing several abilities associated with them, including Chlorophyll, Flower Gift, Harvest, Leaf Guard, and Solar Power. It also allows Solar Beam to be used instantly, causes Moonlight, Synthesis, and Morning Sun to recover ⅔ of max HP, and doubles stat increases when using Growth. On the other hand, it decreases the accuracy of Thunder and Hurricane to 50%. All Pokémon are immune to freezing while the sun is intense.

Intense sunlight turns Castform into a Fire-type and changes Weather Ball to a Fire-type move and doubles its power.

Rain

Main article: Rain
Icon from Black 2 and White 2

Rain is called by the move Rain Dance and the ability Drizzle, and is the most common naturally occurring weather condition. It increases the power of Water-type moves by 50%, and decreases the power of Fire-type moves by the same amount. It prevents Thunder and Hurricane missing. On the other hand, it causes Solar Beam to only deal half of its normal damage, and lowers HP recovered from Moonlight, Synthesis, and Morning Sun to ¼ of max HP. It is associated with the abilities Dry Skin, Hydration, Rain Dish, and Swift Swim.

Rain turns Castform into a Water-type and changes Weather Ball to a Water-type move and doubles its power. Sliggoo evolves into Goodra starting at level 50 when leveled up during rain in the overworld.

Sandstorm

Sandstorms are called by the move Sandstorm and the ability Sand Stream. It damages all Pokémon who are not Rock-, Ground-, or Steel-type, and increases the Special Defense of Rock-type Pokémon by 50% when in effect. It causes Solar Beam to only deal half of its normal damage, and lowers HP recovered from Moonlight, Synthesis, and Morning Sun to ¼ of max HP. It is associated with the abilities Sand Veil, Sand Rush, and Sand Force. Pokémon with the aforementioned abilities, as well as those with Overcoat and Magic Guard, or hold Safety Goggles, are immune to Sandstorm damage.

Hail

Fog

Fog redirects here. For the Badge given by Morty, see Badge → Fog Badge.

Fog is a weather condition that has appeared as an aesthetic effect since Generation III, but has only had an effect in battle in Pokémon Diamond, Pearl, and Platinum, as well as Pokémon Battle Revolution. It is not called by any move or ability, and only occurs naturally. Its effect is largely negative, lowering the Accuracy of all Pokémon battling, and causing Moonlight, Synthesis, and Morning Sun to recover ¼ of max HP. It also makes obstacles and trainers difficult to see on the field. It can be removed if Defog is used.

Castform does not change form or type in fog, and it does not change Weather Ball's type, but it still doubles its power.

Trivia

  • All weather-creating Abilities (Drought, Drizzle, Sand Stream, and Snow Warning) debuted the generation after their respective moves/weather (Sunny Day, Rain Dance, Sandstorm, and Hail).
  • Fog first appeared in Generation III on Mt. Pyre, but had no effect on battles.
  • Several lines of unused weather effect text appear within the code of the games. Notably, quotes for fog exist within the text for Black and White, implying that fog was planned to exist in Black and White.
