Theweather (Japanese:天気weather) is a set of mechanics in thePokémon games.

In the core series games

In thecore series, the weather changes the battle environment, activatingAbilities, modifying certainmoves, and potentially damaging thePokémon in battle or affecting theirstats. They have been included in everycore series game sinceGeneration II. Only one type of weather may be present at a time; an effect that creates weather will remove the previous weather.

In Generation II, the only way to cause weather was by a Pokémon using amove in-battle.Generation III introducedweather-related Abilities as well as overworld weather; starting a battle in an overworld location with weather would cause that weather to be automatically present from the beginning of the battle.Generation IV introduced four held items (Heat,Damp,Smooth, andIcy Rocks) that increase the duration of weather caused byweather-changing moves orAbilities.Generation V introducedseasons, which may affect the weather in certain locations, andGeneration VI introduced a newEvolution method affected by the weather.Generation VIII introduced overworld effects that resemble weather but do not directly correspond with an in-battle weather.

Pokémon battles

List of weather

The following lists all the weather conditions inbattles. Note that inPokémon Legends: Arceus, weather conditions do not behave the same way they do in the other games.

Weather	Image	In-game description	Details
Harsh sunlight		The harsh sunlight weather condition. It boosts the power of Fire-type moves and lowers the power of Water-type moves.	Harsh sunlight strengthens the power ofFire-type moves by 50% and weakens the power ofWater-type moves by 50%. Duringharsh sunlight, no Pokémon can befrozen. InPokémon Legends: Arceus, it instead increases the Speed of Grass-type Pokémon and activatesCherrim's Sunshine Form.
Rain		The rain weather condition. It boosts the power of Water-type moves and lowers the power of Fire-type moves.	Rain strengthens Water-type moves by 50% while weakening Fire-type moves by 50%.
Sandstorm		The sandstorm weather condition. At the end of each turn, it damages all Pokémon that are not Rock, Ground, or Steel types. It boosts the Sp. Def of Rock-type Pokémon.	Any Pokémon that is notRock-,Ground-, orSteel-type will be damaged for1/16 of its maximum HP at the end of each turn. CertainAbilities prevent damage from weather effects, though, and a Pokémon holdingSafety Goggles is also immune to damage from weather effects. Since Generation IV, in a sandstorm, theSpecial Defense ofRock-type Pokémon is increased by 50%.
Hail		The hail weather condition. At the end of each turn, it damages all Pokémon that are not Ice types.	Any Pokémon that is notIce-type will be damaged for1/16 of its maximum HP at the end of each turn. CertainAbilities prevent damage from weather effects, though, and a Pokémon holdingSafety Goggles is also immune to damage from weather effects. This weather was replaced by Snow inGeneration IX.
Snow		The snow weather condition. It makes Blizzard more likely to hit and boosts the Defense of Ice-type Pokémon.	Snow increases theDefense ofIce-type Pokémon by 50%. This weather condition replaces Hail inGeneration IX.
Fog		N/A	This weather condition only exists inSinnoh andHisui. A thick fog clouds the overworld and battlefield, reducing theaccuracy of all moves.
Extremely harsh sunlight		The extremely harsh sunlight weather condition. It boosts the power of Fire-type moves and protects Pokémon from Water-type moves.	Sunlight shines more heavily on the battlefield. This has only occurred in the overworld in theHoenn region, inPokémon Omega Ruby, due toGroudon's emergence.
Heavy rain		The heavy rain weather condition. It boosts the power of Water-type moves and protects Pokémon from Fire-type moves.	Rain falls more chaotically around the battlefield.
Strong winds		The strong winds weather condition. The power of moves that are super effective against Flying-type Pokémon is decreased.	Strong winds causesElectric-,Ice-, andRock-type moves to deal neutral damage to Flying-type Pokémon.
Shadowy aura		N/A	Any Pokémon that is not aShadow Pokémon will be damaged for1/16 of its maximum HP. This weather condition is only present inPokémon XD: Gale of Darkness and has no overworld manifestation anywhere.

Moves affected by weather

Certain specific moves are also affected in special ways by the weather.

• The recovery movesSynthesis,Morning Sun, andMoonlight restore more HP than usual in harsh sunlight, and less than usual in most other weather.
  • In Generation II, during no weather they normally restore ¼ total HP, duringharsh sunlight they normally restore ½ total HP, and during other weather they normally restore ⅛ total HP. Except in link battles, the amount of HP restored is doubled if it is the move's preferred time of day (morning for Morning Sun, day for Synthesis, night for Moonlight).
  • From Generation III onward, during no weather orstrong winds they restore ½ total HP, duringharsh sunlight they restore ⅔ total HP, and during other weather they restore ¼ total HP.
• The moveShore Up restores ⅔ of the user's total HP during a sandstorm; outside of a sandstorm, it only restores ½ total HP.
• The accuracy ofThunder,Hurricane,Blizzard,Bleakwind Storm,Wildbolt Storm, andSandsear Storm are affected by the weather.
  • FromGeneration IV onward, during hail Blizzard ignores accuracy and evasion checks.
  • During rain, Thunder and Hurricane ignore accuracy and evasion checks; during harsh sunlight, Thunder and Hurricane only have 50% accuracy.
  • In Generation IX, during rain, Bleakwind Storm, Wildbolt Storm, and Sandsear Storm ignore accuracy and evasion checks.
  • InPokémon Diamond and Pearl only, Blizzard and Thunder also have a 30% chance to hit throughProtect orDetect when used in hail or rain, respectively.
• Solar Beam andSolar Blade become one-turn moves in harsh sunlight, skipping their charge turn; in rain, sandstorm, hail, and fog, the moves' powers are halved.
• Electro Shot becomes a one-turn move in rain, first raising the user'sSpecial Attack and then attacking in the same turn.
• From Generation V onward, during harsh sunlightGrowth increases the user'sAttack andSpecial Attack by two stages each instead of one.
• In Generations IV and V, andPokémon X and Y, when used as afield moveSweet Scent fails if there is a non-aesthetic weather effect in the area.
• The moveAurora Veil can only be used successfully during hail or snow; otherwise it fails.

Activated Abilities

The following Abilities are activated when a type of weather comes into effect. Most of these Abilities have no effect if no weather is active.

In addition to the above Abilities,Harvest is guaranteed to restore a Berry whenever it triggers in harsh sunlight, and the AbilitiesOvercoat andMagic Guard will prevent weather-related damage.

Castform and Weather Ball

Main article:Castform (Pokémon)

Main article:Weather Ball (move)

Castform is a Pokémon uniquely designed to take advantage of the weather. ItsAbility,Forecast, causes it to changeform when a type of weather is present. Forecast does not cause a unique change for every possible type of weather, though.

Normal  Normal  During clear skies,fog, sandstorm,shadowy aura, andstrong winds

Sunny Form  Fire  Duringharsh sunlight andextremely harsh sunlight

Rainy Form  Water  Duringrain andheavy rain

Snowy Form  Ice  Duringhail/snow

Weather Ball is amove that uniquely takes advantage of the weather. InGeneration III, it was introduced along with Castform and was Castform'ssignature move.

Whenever there is a type of weather present, Weather Ball's base power will double to 100. Weather Ball's type also changes during most types of weather.

Because of its Ability, Castform has a unique synergy with Weather Ball that no other Pokémon that can learn Weather Ball has. In harsh sunlight, rain, or hail, Castform will always getSTAB thanks to its Ability.

Causing weather

Most of the types of weather have amove orAbility that will cause that weather.

Air Lock andCloud Nine also suspend the effects of weather while they are active.

Weather normally lasts for 5 turns when it is called by a move. Prior toGeneration VI, weather created by an Ability would continue until the battle ended or another type of weather took its place; since Generation VI, weather created by Abilities also lasts for only 5 turns, with the exception of weather created byDesolate Land,Primordial Sea, andDelta Stream. As ofGeneration IX, moves and Abilities that change the weather will fail if a weather condition is occurring in the overworld.

If multiple Pokémon with Abilities that change the weather are sent in simultaneously, the Abilities activate in order fromfastest Pokémon to slowest Pokémon (or the reverse duringTrick Room); this means that the slowest Pokémon's Ability will override the other Abilities.

If a Pokémon holding one of fourheld items creates weather that would otherwise last 5 turns, it instead lasts 8 turns. The rock that affects each type of weather is shown below.

Harsh sunlight	Rain	Sandstorm	Hail/Snow
Heat Rock	Damp Rock	Smooth Rock	Icy Rock

Visual indicators

Generation V

InGeneration V, the weather was given an icon which appeared on the DS or 3DS's bottom screen in a battle whenever weather was occurring. Since fog and shadowy aura do not appear in-battle in Generation V, they have no icons. When there is no weather, no icon is shown.

The "Status Info" view inPokémon Legends: Arceus

Generation IX

InPokémon Scarlet and Violet, weather conditions can be seen in-battle by pressingY forCheck Status, listed under "Active Battle States and Effects". Weather conditions caused by the overworld will not display a duration, and they may appear or disappear without notice as the overworld weather changes.

Overworld

This section is incomplete. Please feel free to edit this section to add missing information and complete it.

Overworld weather varies between games. There are a larger variety of overworld weather conditions compared to a battle, however some conditions do not affect battles. If a weather condition is present in aRoute, sector of theWild Area or location withinPokémon Legends: Arceus orPokémon Scarlet and Violet, the weather will appear in every battle and last until it is replaced by another weather, and returns to the original weather in the overworld. In addition, Defog may clear fog from an overworld area (inSinnoh only).

Diamond Dust is a special, purely aesthetic version of light snow, and replaces hail where applicable, allowing the player to battle without the effects of hail, without changing the weather manually. It first appeared as anEaster egg inPokémon Diamond and Pearl, and has appeared in severalcore series games since.

Weather-dependent Evolution

Starting at level 50,Sliggoo (as well as itsHisuian form) will evolve intoGoodra if it is leveled up duringrain in the overworld. InGeneration VII only, it can also evolve duringfog.

First Evolution		Second Evolution
	+ Level 50+ (duringrain) →
Sliggoo  Dragon		Goodra  Dragon

First Evolution		Second Evolution
	+ Level 50+ (duringrain) →
Sliggoo Hisuian Form  Steel  Dragon		Goodra Hisuian Form  Steel  Dragon

Johto

• InPokémon HeartGold and SoulSilver,Route 33 is alwaysrainy.
  • TheLake of Rage is also rainy on mostdays of the week, but is clear on Wednesdays.
• The snow on the summit areas ofMt. Silver Cave will activateHail in battles.

Hoenn

InHoenn, several areas have weather conditions that occur naturally:

• Fog is present at the summit ofMt. Pyre, but it has no effect in battles.
• There is always a sandstorm onRoute 111
• It frequently rains onRoute 119, with clear skies only on one in four days.
• It always rains on a section ofRoute 120 between the two log bridges corresponding roughly where theAncient Tomb is located.
• It rains on one in four days inRoute 123 - at the same time, the rain on Route 119 will be thundery.

Several weather conditions are also triggered by in-game events:

• WhenKyogre is awakened, a rain/heavy rain is present. In contrast to natural rain, rain summoned by Kyogre includes thunderstorms as well as more rain.
• WhenGroudon is awakened, harsh sunlight/extremely harsh sunlight is present.
• Pokémon Emerald involves both Groudon and Kyogre being awakened in that order. Groudon is awakened first but does not immediately change the weather; once Kyogre is awakened, the weather will alternate between rain and harsh sunlight.

The requisite visit toSeafloor Cavern to defeatMaxie^ROR/Archie^SEAS will subsequently awaken Groudon/Kyogre and cause the respective weather condition to affect four cities:Lilycove City,Mossdeep City,Sootopolis City andEver Grande City, as well as their connecting routes east of Lilycove. InPokémon Emerald, after reaching theSky Pillar during the crisis, its unique weather distortion will spread to the routes east of but not includingPacifidlog Town as well. While the weather condition is present, a different background music plays, overriding the usual city and route themes as well as the surfing and cycling themes.

Sinnoh

• Asandstorm is present onRoute 228 at all times.
• Fog obscures the player's overworld vision on the northern section ofRoute 210, the basement floor ofMount Coronet, the upper floors of theLost Tower, the postgame section of Sinnoh'sVictory Road, andTurnback Cave. It can be removed usingDefog.
  • InPokémon Brilliant Diamond and Shining Pearl, fog activatesMisty Terrain in battles.

Unova

InUnova,seasons play a significant role in what weather conditions can form in the overworld.

InGeneration V, it is possible to temporarily remove overworld weather by saving the game, setting the DS'sclock to one month later (to change the season), loading the save file, andcatching a Pokémon without leaving the area. This works even if the area always has the same weather regardless of the season.

Kalos

Rain will occur on some days in many few areas inPokémon X and Y.

It will always rain on Wednesdays inKiloude City.

Rain and fog may appear inLumiose City inPokémon Legends: Z-A.

Alola

• ASandstorm will be present inHaina Desert between 5:00 PM and 9:59 AM. Otherwise, the weather will beHarsh Sunlight.

Rain will occur in several locations, and depends on certain conditions:

• InPokémon Sun and MoonBrooklet Hill will rain duringLana'strial, after catching or defeating the firstWishiwashi, and before completing the trial.
  • InPokémon Ultra Sun and Ultra Moon, it will instead rain between catching/defeating the second Wishiwashi and before completing the trial.
• Lush Jungle, Brooklet Hill,Malie City,Malie Garden, Routes10,11,12,13,Blush Mountain, andSecluded Shore will rain between 5:00 PM and 6:00 PM.
• Tapu Village andRoute 14 will rain on some days.
• Exeggutor Island will rain at certain times with two different intensities, light rain will occur between 10 AM - 3:59 PM, and strong rain will occur between 6 PM - 11:59 PM.
• Route 17 will always rain.

Galar

InPokémon Sword and Shield, overworld weather effects mostly occur in theWild Area,Isle of Armor, andCrown Tundra, including those that do not directly correspond to the in-battle weather mechanic.

InPokémon Legends: Arceus, weather is a mechanic that is completely controlled by the environment, and it is reset each day. Weather plays a role in the spawn distributions of certain wild Pokémon (Ponyta and thealphaRapidash inHorseshoe Plains do not spawn during fog, rain, and thunderstorm; additionally, inIcebound FallsLucario spawns only during a blizzard, except for the alpha) and also has certain in-battle effects. There are nomoves that can affect the weather.

Icon	Weather	Effect in battle
	Sunny	The Speed of Grass-type Pokémon is boosted by 33%. Cherrim's Sunshine Form will be active.
	Harsh sunlight	The Speed of Grass-type Pokémon is boosted by 33%. Cherrim's Sunshine Form will be active. Space-time distortions will not appear.
	Cloudy
	Rain	Damage dealt by Fire-type moves is reduced by 25%.
	Thunderstorm	Damage dealt by Fire-type moves is reduced by 25%. Space-time distortions will not appear.
