How to Find Swarm Pokemon

Unlock National Dex First

To be able to encounter Swarm Pokemon, you need to become Champion and unlock the National Dex. Unlock the National Dex by encountering all Pokemon on the Sinnoh Dex, then speak to Professor Rowan in his lab in Sandgem Town to receive the National Dex.

How to Unlock the National Dex

Talk to Sister of Lucas/Dawn

After getting the National Dex, you can unlock the ability to encounter Swarm Pokemon by talking to the sister of the Professor's Assisstant (Lucas/Dawn) in the house south of the lab in Sandgem Town.

Find Swarm Pokemon in Overworld

After talking to the sister, go to the route mentioned and you'll see the daily Swarm Pokemon species appear in the tall grass of the overworld! Run around the tall for a chance to trigger a wild encounter with the Swarm Pokemon. Running towards the overworld depiction of the Pokemon doesn't do anything, as they disappear when you go near.

You may use the Poke Radar to chain Swarm encounters

Since swarming Pokemon are added to the encounters of a route, you may also use the Poke Radar to chain for them. This can be your chance to get these swarming Pokemon with Hidden Abilities, good IVs, or maybe even a shiny!

How to Use the Poke Radar and List of Pokemon

Daily Swarm Pokemon listed on Menu Screen

After unlocking the Swarm Pokemon feature, you can view the daily Swarm Pokemon and the route they're found in at the bottom of the Menu Screen. Be sure to check it daily!

Only 1 Pokemon species and route are mentioned for each day (up until 11:59pm). It's not possible to change the selection of the Pokemon via soft reset or changing the date and time of your device.

Join or create a group to synchronize the daily Swarm Pokemon

When part of a group, all the people in your group will be given the same Pokemon species and location for that day.
