You can find TM37 Sandstorm on Route 228, which is northwest of the Battle Zone’s Resort Area. No Hidden Moves are necessary to reach the TM, but this area is only available after defeating the Elite Four and the Champion in the Pokémon League.
And this is the only location where you can get TM37 in the game.
As for the move itself:
Sandstorm is a Rock-type status move that summons a sandstorm for five turns. At the end of every turn, the sandstorm hurts all Pokémon in play except Rock, Ground, and Steel types.
TM37 Sandstorm Location (Step-by-Step)
TM37 Sandstorm is found on Route 228, directly to the northwest of the Resort Area in the Battle Zone.
Here’s exactly where to go to get the TM:
From the Resort Area’s Pokémon Center, cross the bridge to the north.
On the other side of the pond, continue north to leave the Resort Area and enter onto Route 229.
Where the trail splits at the Resort Area/Route 229 sign, head northward through the tall grass, past the two Ace Trainers.
Veer to the northwest here toward the gap in the trees.
A sandstorm will flare up as Route 229 becomes Route 228.
Hug the eastern wall at this point, but keep moving northward through the narrow canyons.
Continue heading north, moving through the narrow gaps.
Eventually you will see a Berry plot on your left near some grass. And directly north of this berry plot on the other side of a hill is a Poké Ball item on the ground – this is your TM.
Walk around the hill and interact with this item to add TM37 Sandstorm to your list of TMs.
This is the only copy of TM37 Sandstorm in the game, so be very selective when choosing a Pokémon to use it on.
Sandstorm Details and Uses
Sandstorm is a Rock-type status move that whips up a sandstorm for five turns. All Pokémon in play, except those whose types are Rock, Ground, and Steel, will be damaged at the end of every turn of the sandstorm’s duration.
The amount of damage received during every turn is equal to 1/16 of the Pokémon’s maximum HP.

Sandstorm is an interesting move, but it’s only useful for a select handful of Pokémon.
And even for those, it would usually be better to focus on doing damage with a powerful attack than using the turn setting up a mild inconvenience for the opponent.
The ideal Pokémon to teach Sandstorm to would be a Rock-type Pokémon with the Sand Veil Ability, also holding a Smooth Rock.
- Pokémon with the Sand Veil ability get a 20% boost in evasion from sandstorms and immunity from sandstorm damage, and the Special Defense stat of Rock-type Pokémon increases by 50% during a sandstorm.
- The Smooth Rock will increase the duration of a Sandstorm from 5 turns to 8 turns, allowing for a single sandstorm to potentially eliminate 50% of a Pokémon’s total HP on its own.
Miscellaneous information about Sandstorm:
- TM37 Sandstorm can be sold for 1000 PokéDollars, although that is not recommended due to its scarcity.
- If heavy rain, extremely harsh sunlight, or strong winds are affecting the battlefield, Sandstorm will fail.
- The moves Moonlight, Synthesis, and Morning Sun will only restore ¼ of their users’ maximum HP during a sandstorm.
- Sandstorm will turn the move Weather Ball into a Rock-type move.
- Pokémon in the semi-invulnerable turn of the moves Dig or Dive will not be affected by sandstorm damage.
- When used in a Pokémon Contest, Sandstorm will earn the user 2 Appeal Points and prevent the Voltage from going up in that turn.
