Where do you get surf on poke mon white in driftveil?

You can't get Surf in Driftveil City in Pokémon White. Here's why:

* Surf is learned later in the game: You won't encounter the move Surf until you reach a later stage in the game, after Driftveil City.

* Driftveil City is inland: Driftveil City is not located near any bodies of water that you would need Surf to traverse.

If you're looking for Surf, keep progressing through the main story. You'll eventually come across a place where you can learn the move.
