Weather has always played a meaningful role in Pokémon games, and Pokémon Pokopia takes that tradition further by putting the power directly in your hands. Whether you need a downpour to coax out a Goomy or blazing sunshine to find a Charmander, knowing how to flip the weather is essential for completing your Pokédex. The good news? The system is surprisingly accessible once you understand the pieces involved.
How Do You Change the Weather in Pokémon Pokopia?
Changing the weather comes down to building the right habitat and bringing the right Pokémon to it. You have two options to set up: a Sunny Day Site or a Rain Dance Site. Both habitats share the same construction recipe, which keeps things simple.
To build either site, you need:
- Two Castform Weather Charms (hung on the wall, one on each side)
- One dish of Plated Food (any food works)

Rain Dance Site setup
How the Castform Weather Charm Actually Works
Here is the clever part most players miss: the Sunny Day Site and Rain Dance Site are technically the same habitat. The Castform Weather Charm is a flip item. Interact with it and it rotates between its Rain Form and Sunny Form. Both charms on your wall need to match the weather you want to trigger. If you want rain, flip both to Rain Form. If you want sun, flip both to Sunny Form.
tip
Always double-check that both Castform Weather Charms are set to the same form before placing your food. Mismatched charms will not trigger the weather change correctly.
Which Pokémon Perform the Weather Dance?
Once your habitat is ready with food on the plate, you need to bring a Pokémon over to perform the dance. The Pokémon you choose depends on the weather you want.
The Pokémon will eat the food, perform either a Rain Dance or Sunny Day, and the weather shifts shortly after. Any Pokémon with the matching specialty will do the job, so use whoever you have available.
How Do You Get Castform Weather Charms?
You will need at least two Castform Weather Charms to build your first weather habitat. Thankfully, there are several reliable ways to collect them.
Story Reward
You will receive your first Castform Weather Charm as part of the main story. When you reach the point in Withered Wastelands where you need to raise humidity and make it rain with Slowpoke, speak to Professor Tangrowth and he will hand one over.
Pokémon Center Terminal
A second charm can be purchased directly from the Pokémon Center Terminal. This is the fastest way to get the pair you need for your first habitat.
Dream Islands and Lost Relics
For any additional charms beyond your first two, keep these methods in mind:
- Dream Islands: Climb the ladder in the starting tower of every Dream Island you visit. A Castform Weather Charm is typically waiting there.
- Lost Relic drops: Charms appear occasionally as Lost Relic items found throughout the world.
tip
Dream Islands are one of the most consistent sources for extra Castform Weather Charms. Make it a habit to check the starting tower ladder on every visit.
What Pokémon Only Appear in Certain Weather?
Weather-exclusive spawns are the main reason to actively control conditions in Pokémon Pokopia. Without the right weather active, certain Pokémon simply will not appear, which means your Pokédex will stay incomplete.

Goomy spawns in rain only
Rain-Exclusive Pokémon
These Pokémon only show up when rain is active:
- Goomy
- Sliggoo
- Goodra
Sunny-Exclusive Pokémon
These Pokémon only appear under sunny conditions:
- Charmander
- Charmeleon
- Charizard
- Cacnea
warning
If you are hunting weather-exclusive Pokémon and they are not appearing, confirm that the weather change has fully taken effect. There is a short delay after the dance before conditions shift.
What Is the Fastest Way to Set Up Weather Control?
If you want to get your first weather habitat running as quickly as possible, here is the most efficient path:
- Progress through the Withered Wastelands story mission until Professor Tangrowth gives you your first Castform Weather Charm.
- Head to the Pokémon Center Terminal and purchase the second charm.
- Build your habitat, hang both charms on the wall, and set them to match your desired weather.
- Place any food on the Plated Food dish.
- Bring a Water Specialty or Burn Specialty Pokémon to the site and let them perform the dance.
- Wait briefly for the weather to change, then start hunting.
