What it does

For 5 turns, the weather becomes Sunny Day. The damage of Fire-type attacks is multiplied by 1.5 and the damage of Water-type attacks is multiplied by 0.5 during the effect. Lasts for 8 turns if the user is holding Heat Rock. Fails if the current weather is Sunny Day.

Who carrys it

22 of the 282 Pokémon measured on the Regulation M-B ladder carry Sunny Day. The one that matters most is Whimsicott, which is on 22.5% of teams and carrys it on 8.1% of its sets. The full list is above, ordered by how much of the format each one is.

What it hits

As a Fire move it is super effective against Bug, Grass, Ice and Steel, resisted by Dragon, Fire, Rock and Water. 5 other Fire moves appear in this format: Heat Wave, Flare Blitz, Will-O-Wisp, Overheat, Flamethrower.

Who could and does not

168 Pokémon legal in this regulation can learn Sunny Day at all, against the 22 that actually bring it. The gap is the interesting number: it is the set of Pokémon that have the option and decline it. The most-played of those are Incineroar, Garchomp, Sneasler, Farigiraf, Sylveon and Maushold — each of them measured on the ladder, each of them leaving this move on the shelf.

How concentrated it is

Across the ladder, Sunny Day accounts for an expected 0.03 of the six slots on an average team, which makes it the 101st most-brought of the 126 moves this format runs. 63% of that comes from Whimsicott alone, so it is really one Pokémon’s move rather than the format’s. Its carriers are mostly Grass (5), Dark (4) and Psychic (4).

Where these numbers come from

Usage is Smogon's published statistics for the Regulation M-B VGC ladder, and the description is the one shipped in the Pokémon Showdown data set. Both are regenerated on every build rather than written by hand, so this page follows the format instead of trailing it. Take any of it to the team builder or the damage calculator.
