You can find TM18 Rain Dance on the deck of Sea Mauville, a half-sunken ship located north of Route 108. To access Sea Mauville, you’re going to need a Pokémon with Surf.
Rain Dance summons a heavy rain that lasts for five turns, raising the power of all Water-type moves. The rainy weather mainly benefits Water-types, as a number of abilities and moves interact with it.
Pokémon that can learn Thunder and Hurricane also benefit from Rain Dance, making both moves 100% accurate.
TM18 Rain Dance Location (Step-by-Step)
While you need HM07 Dive to explore Sea Mauville fully, you won’t need it to get the TM. To reach the location of TM18 Rain Dance, you’ll only need:
- The fifth Gym Badge from Petalburg City to use Surf outside of battle
- A Pokémon that knows Surf
If you haven’t been to Sea Mauville yet, head to the beach on Route 109. This is the route south of Slateport City. Then here’s the step-by-step directions you should follow to reach the TM:
Step 1: Use Surf near the shore by the docks.
Step 2: Surf going southwest until you end up on Route 108.
Step 3: When you’re in Route 108, head west.
Step 4: Then head north to reach Sea Mauville’s entrance.
Step 5: Surf over to the side of the ship.
Step 6: Head up to the ship’s deck.
Step 7: Turn right, past the entrance to the ship’s interior.
Step 8: The TM for Rain Dance should be along the staircase here.

When Rain Dance is used, rainfall will start on the field lasting five turns, replacing any other existing weather effects that may be present.
During the rain, various moves have additional effects that mainly benefit Water, Electric, and Flying-types.
Here’s a list of what’s affected by the rainy weather:
- Increases Water-type moves’ base power by 50%
- Decreases Fire-type moves’ base power by 50%
- Solar Beam requires two turns to charge instead of one
- Thunder and Hurricane’s accuracy are increased to 100%
- Morning Sun, Moonlight, and Synthesis recover 25% of the user’s HP instead of 50%
When using Rain teams, it might not be a good idea to use Water-type Pokémon exclusively. Take advantage of the accuracy boost to Hurricane and Thunder, as they’re excellent moves without the downside of only having 70% accuracy.
A number of abilities also trigger when the rainy weather is in effect:
- Dry Skin – Recovers 1/8 its HP every turn and 1/4 its HP when hit by a Water-type move
- Forecast – Changes Castform to its Rainy Form, its Water-type form
- Hydration – Cures any status conditions at the end of each turn
- Rain Dish – Recovers 1/16 its HP every turn
- Swift Swim – Doubles the user’s Speed in the rain
Among this list, Swift Swim stands out the most; with it, Mega Swampert’s mediocre Speed stat will be difficult to outspeed when doubled.
Tip: The ability Drizzle makes the weather rainy when entering battle. This is the most efficient way of running a Rain team, since you don’t have to use a turn setting up rain.
You can also let your Drizzle user hold a Damp Rock, which extends the duration of the rainy weather from five turns to eight turns. Only Politoed and Kyogre have Drizzle as their ability in Pokémon Omega Ruby and Alpha Sapphire.
