The only copy of TM18 Rain Dance is located at the western edge of Route 223. The TM will be sitting behind a cluster of large rocks, and you’ll need Surf to traverse the water to reach the TM.
Rain Dance is a non-damaging, Water-type status move that causes rainy weather for five turns, empowering Water-type moves. It does not inflict damage.
Rainy weather can also activate/transform certain moves and Abilities, as listed below.
TM18 Rain Dance Location (Step-by-Step)
You will have access to TM18 Rain Dance as soon as you’re able to enter Sunyshore City, right after defeating Team Galactic on Mt. Coronet.
To reach TM18’s location, make sure you have a Pokémon with Surf in your party.
Then head north from the Sunyshore Pokémon Center.
Continue northward, past the Poké Mart and Sunyshore Market, where the paved street ends.
A short distance north of here is a small beach beside the ocean.
Use Surf on the water here, and resume journeying north.
Continue north past the patch of shallow water and the swimmer NPCs.
After you pass two swimmers, make sure you’re near the western side of Route 223.
You will see a third swimmer wearing a white swim cap, and beside him is an assortment of rocks and hills. They might appear randomly placed, but there is a narrow pathway that you can travel through between the rocks.
Wind your way through the path, then head north to find a Poké Ball item sitting in some shallow water.
Pick this up to acquire TM18 Rain Dance.
This is the only copy of TM18 Rain Dance in the game, so be sure to save it for the right Pokémon.
Rain Dance Details + Uses
Rain Dance is a non-damaging, Water-type status move. It causes a rainstorm, which boosts Water-type moves by 50% and dampens Solar Beam and Fire-type moves by the same amount.
The move lasts for 5 turns, unless the user is holding a Damp Rock, which will extend the duration to 8 turns.

- Pokémon with Forecast will transform into Water type.
- In the rain, the move Thunder, which usually has an accuracy stat of 70%, will ignore accuracy and evasion checks to always hit the target.
- The effects of the HP-replenishing moves Morning Sun, Synthesis, and Moonlight will be dampened in rainfall, restoring only ¼ of the user’s maximum HP every turn.
- In the rain, Weather Ball will become a Water-type move and its base power will increase to 100.
