You can buy TM07 Hail from the Technical Machine shop inside the Royal Avenue Pokémon Center. This same shop sells TMs for the other three weather moves: Sunny Day, Rain Dance, and Sandstorm.

Hail Details + Use
|Hail Move Details|
Hail is a weather move that causes a hailstorm when used in battle.
The hailstorm will last for five turns. Pokémon equipped with an Icy Rock will extend Hail to eight turns.
In battle, Hail will damage all Pokémon for 1/16 (6.25%) of their maximum HP every turn.
Ice-type Pokémon are immune to damage from hailstorms. Pokémon with the abilities Magic Guard and Overcoat are also immune to damage from Hail. Having Safety Goggles as a held item will make a Pokémon immune to weather damage.
In Generation VII, Hail teams became viable with the additions of Aurora Veil and Slush Rush.
- Aurora Veil is a defensive move that halves the damage from physical and special attacks. This move can only be used during a hailstorm.
- Slush Rush is an ability exclusive to the Alolan Sandslash and Beartic lines. Pokémon with Slush Rush will double their Speed stat while Hail is active.
As a move, Hail isn’t a popular choice for weather teams. Running a Pokémon with the Snow Warning ability is a more effective strategy.
Pokémon with Snow Warning will immediately cause a hailstorm when they enter a battle. Unlike Hail, Snow Warning doesn’t take a full turn to set up.
That being said, some Hail teams may opt to run a secondary weather setter. This Pokémon plays a backup role in case the Snow Warning user gets taken down. In this case, the secondary setter will have Hail as part of their moveset.
