From Bulbapedia, the community-driven Pokémon encyclopedia.
Sunny Day (Japanese: にほんばれ Clear Sky) is a non-damaging Fire-type move introduced in Generation II. It has been TM11 since Generation II.
When this move is used, the sunlight will brighten the field. This effect will last for 5 turns. This clears any other weather effect, and is usable even when it's already sunny.
While Sunny Day is in effect, the base power of Fire-type moves will be increased by 50%, and the base power of Water-type moves will be decreased by 50%. In addition to this, the moves Synthesis, Morning Sun, and Moonlight will recover twice as much HP as under clear conditions, and SolarBeam will not require a turn to charge.
This move now fails when the weather is sunny.
Synthesis, Morning Sun and Moonlight will now instead recover ⅔ of the user's HP in intense sunlight. Additionally, Castform (due to its Ability, Forecast) and Weather Ball become Fire-type. Pokémon with Chlorophyll will have their Speed doubled.
This move lowers the accuracy of Thunder to 50%. If a Heat Rock is held when Sunny Day is used, the duration of sunlight lengthens from 5 to 8 turns. Additionally, the following Abilities will have the effects listed while the sun is shining:
- Pokémon with the Dry Skin Ability will lose ⅛ of their maximum HP at the end of each turn
- Pokémon with the Flower Gift Ability will raise the team's Attack and Special Defense by 50%
- Pokémon with the Solar Power Ability will have their Special Attack raised by 50% and lose ⅛ of their HP each turn
- Pokémon with the Leaf Guard Ability will be immune to being inflicted non-volatile status ailments
Hurricane's accuracy will be lowered, similarly to Thunder. Growth will raise the user's Attack and Special Attack by two stages instead of just one. Harvest will never fail to restore a Berry.
