Reason: Generation VI and VII details; Gates to Infinity descriptions
The weather (Japanese: 天気 weather) is a set of mechanics in the Pokémon games that change the battle environment, activating Abilities, modifying certain moves, and potentially damaging the Pokémon in battle or affecting their stats. They have been included in every core series game since Generation II. In battle, weather is either determined by the location of a battle, due to overworld weather, or by a Pokémon creating a new type of weather with a move or Ability. Only one type of weather may be present at a time, and only the most recent type of weather will take effect.
In Generation II, only moves that cause weather were introduced and weather was only present in battles, not in the overworld. Generation III introduced overworld weather and weather-related Abilities, as well as a new weather-causing move. The biggest modification to weather in Generation IV was the introduction of four held items (Heat, Damp, Smooth, and Icy Rocks) that increase the duration of weather caused by weather-changing moves or Abilities with effects on weather conditions. Generation V mostly introduced greater overworld weather variability, especially in seasons affecting the weather in certain locations.
Types of weather and effects
- Clear skies: Actually the absence of weather. This is the weather found in most locations.
- Harsh sunlight: Strong sunlight shines on the battlefield. It is one of the rarest conditions to be seen in the overworld.
- Rain: Rain falls on the battlefield. Different variations of this weather may appear on the overworld. This is the most common weather pattern that may be found on routes and occasionally in cities.
- Sandstorm: Stinging sand whips across the battlefield. In Generations III through V, every new region had a specific area where a sandstorm was always occurring.
- Hail: Pelting hail falls on the battlefield. Different variations of this weather may appear on the overworld. There may also be benign falling snow that does not cause hail in a battle.
- Shadowy aura: Bursts of light rain down from a shadowy aura in the sky. This type of weather is only present in Pokémon XD: Gale of Darkness and has no overworld manifestation anywhere.
- Fog: A thick fog clouds the battlefield. This only had an in-battle effect during Generation IV, but it has been present in the overworld in other Generations in a purely aesthetic form.
- Strong winds: A strong air current blows across the battlefield. This weather can only be present in battle as a result of Mega Rayquaza's Ability.
There is also a glitch that occurs in Pokémon Platinum, HeartGold and SoulSilver, called acid rain, that results in the simultaneous occurrence of all then-existing weather conditions at once, damaging all Pokémon on the field.
In Generation 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.
In Generation VI onwards, the background of the bottom screen shows an animation of the current weather.
In Pokémon Sword and Shield, there are nine kinds of weather that can appear in the overworld.
|Icon||Weather||Pokémon||Effect in battle|
|Clear (はれ)||Normal, Grass, Flying||—|
|Cloudy (くもり)||Fighting, Poison, Dark||—|
|Rain (あめ)||Water, Bug||Rain|
|Thunderstorm (豪雨)||Water, Electric, Dragon||Rain, Electric Terrain|
|Blizzard (吹雪)||Ice, Steel||Hail|
|Harsh sunlight (ひでり)||Fire, Ground||Harsh sunlight|
|Sandstorm (砂嵐)||Ground, Rock||Sandstorm|
|Fog (霧)||Psychic, Ghost, Fairy||Misty Terrain|
|Clear skies||Harsh sunlight||Extremely harsh sunlight||Rain||Heavy rain||Sandstorm||Hail||Shadowy aura||Fog||Strong winds|
|Move||Defog*||Sunny Day||—||Rain Dance||—||Sandstorm||Hail||Shadow Sky||—||—|
|Ability||—||Drought||Desolate Land||Drizzle||Primordial Sea||Sand Stream, Sand Spit||Snow Warning||—||—||Delta Stream|
In addition, Defog may clear fog from an overworld area (in Generation IV only). It is the only move that has any effect on weather in the overworld.
Weather normally lasts for 5 turns when it is called by a move. Prior to Generation 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 by Desolate Land, Primordial Sea, and Delta Stream.
If multiple Pokémon with Abilities that change the weather are sent in simultaneously, the Abilities activate in order from fastest Pokémon to slowest Pokémon (or the reverse during Trick Room); this means that the slowest Pokémon's Ability will override the other Abilities.
If a Pokémon holding one of four held 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.
Three of the types of weather can do damage to Pokémon in battle at the end of a turn. In a sandstorm, hail, or shadowy aura, any Pokémon that is not Rock-, Ground-, or Steel-type; Ice-type; or a Shadow Pokémon (respectively) will be damaged for 1/16 of its maximum HP. Certain Abilities prevent damage from weather effects, though, and a Pokémon holding Safety Goggles is also immune to damage from weather effects.
Sandstorm and fog both affect the stats of Pokémon on the battlefield. Since Generation IV, in a sandstorm, the Special Defense of Rock-type Pokémon is increased by 50%. In fog, the accuracy of all Pokémon in battle is decreased.
Harsh sunlight and rain both affect the power of certain types of moves. Harsh sunlight strengthens the power of Fire-type moves by 50% and weakens the power of Water-type moves by 50%, while rain does the opposite, strengthening Water-type moves by 50% while weakening Fire-type moves by 50%.
Certain specific moves are also affected in special ways by the weather.
- The recovery moves Synthesis, Morning Sun, and Moonlight 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, during harsh 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 or strong winds they restore ½ total HP, during harsh sunlight they restore ⅔ total HP, and during other weather they restore ¼ total HP.
- The move Shore Up restores ⅔ of the user's total HP during a sandstorm; outside of a sandstorm, it only restores ½ total HP.
- The accuracy of Thunder, Hurricane, and Blizzard is affected by the weather.
- From Generation 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 Pokémon Diamond and Pearl only, Blizzard and Thunder also have a 30% chance to hit through Protect or Detect when used in hail or rain, respectively.
- Solar Beam and Solar Blade become 1-turn moves in harsh sunlight, skipping their charge turn; in rain, sandstorm, hail, and fog, the moves' powers are halved.
- From Generation V onward, during harsh sunlight Growth increases the user's Attack and Special Attack by 2 stages instead of 1 stage.
- In Generations IV and V, and Pokémon X and Y, when used as a field move Sweet Scent fails if there is a non-aesthetic weather effect in the area.
- The move Aurora Veil can only be used successfully during hail; outside of hail, it fails.
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.
Castform and Weather Ball
Castform is a Pokémon uniquely designed to take advantage of the weather. Its Ability, Forecast, causes it to change form when a type of weather is present. Forecast does not cause a unique change for every possible type of weather, though.
During clear skies, fog,
sandstorm, shadowy aura,
and strong winds
During harsh sunlight
and extremely harsh sunlight
During rain and heavy rain
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.
harsh sunlight/extremely harsh sunlight
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 get STAB thanks to its Ability.

Reason: How much does Rainbow Light heal?
Various weather effects appear in certain dungeons in the Pokémon Mystery Dungeon series. Weather effects can change from floor to floor, and can also be altered through the use of Wonder Orbs. In Gates to Infinity, Pokémon will regenerate HP only if the weather is Clear, or if it is holding a Weather Band. In Super Mystery Dungeon and Rescue Team DX, Pokémon can regenerate HP in any weather as long as they do not take damage from the weather condition, or if it is holding a Weather Looplet.
The Abilities Cloud Nine and Air Lock cause the floor to have ineffective weather as long as there is at least one Pokémon on the floor with either of the aforementioned Abilities. Prior to Gates to Infinity, the Abilities change the weather on the floor to Clear and renders Wonder Orbs, moves, and other Abilities that change the weather useless.

Various weather effects appear in Pokémon GO, intended to reflect the actual weather of the player's location. Weather in each local area is updated every hour, on the hour, via Accuweather. Different weathers affect certain Pokémon types, and effects include:
- Increasing the power of moves of boosted types in Gym and Raid Battles by 20% (rounded down to the nearest integer)
- Wild Pokémon with a weather-boosted type...
- spawn more frequently
- award 25% extra Stardust when caught
- are guaranteed at least 4 IVs in each stat.
- are five Power Up levels higher than normal (capped at 35 instead of 30 for wild Pokémon, 25 instead of 20 for Raid Bosses, and 13 instead of 8 for Shadow Pokémon)
- have a swirling, white aura in the overview map
- The form of wild Castform depends on the weather
- The form of wild Cherrim depends on the weather; they appear in Sunshine Form during sunny/clear weather and Overcast Form otherwise
- Cacnea's evolutionary family exclusively spawn in sunny/clear weather
- Lotad's evolutionary family exclusively spawn in rainy weather
Weather bonuses are not applied for Pokémon encounters from Field or Special Research and GO Battle League rewards. Bonus damage is also not applied in Trainer Battles, including Team GO Rocket battles. Exceptions to weather-restricted wild spawns may occur for certain in-game events.
If a weather change causes an existing wild Pokémon spawn to gain (or lose) its weather boost, then its Power Up level will be raised (or lowered) by 5 and its IVs will be re-rolled. However, any weather-dependent forms will remain the same.

Pokémon Masters EX
Weather functions similarly in Pokémon Masters EX as it does in the main series games, though some of the effects are slightly tweaked.
- Sunny: Boosts Fire-type attacks. Additionally, Pokémon cannot be frozen, and previous Pokémon that were frozen prior to the weather condition being implemented will not be frozen anymore after the weather takes effect.
- Rain: Boosts Water-type attacks.
- Hail: Damages Pokémon after every action.
- Sandstorm: Damages Pokémon after every action.
Unlike with the main series games, Ice-type Pokémon are not immune to damage from hail; similarly, Rock-type, Steel-type, and Ground-type Pokémon are not immune to damage from sandstorm. Instead, the effects of hail and sandstorm are nullified by the passive skills Snow Shelter and Sand Shelter, respectively.
Like in the main games, these weather conditions can be triggered with the respective moves (Sunny Day, Rain Dance, Hail, Sandstorm). As well, certain passive skills can activate weather conditions, whether it is after using a sync move or upon entry.
|Passive skill||Weather condition||When it is triggered|
|Cold Front||Hail||Upon entry|
|Dust Kicker||Sandstorm||After sync move|
|Hail Bringer||Hail||After sync move|
|Solarize||Sunny||After sync move|
