Pokemon Let’s Go: How to Unlock Surf (Sea Skim)

Surf is replaced in the Pokemon Let’s Go games by a technique called Sea Skim. Below are details how to obtain this new surfing technique:

Obtaining Surf / Sea Skim:

In order to obtain Sea Skim you will need to have reached Fuchsia City. Once in Fuchsia City defeat the Gym Leader Koga. Upon doing so a gentleman will appear near the Go Park where Lapras is swimming and will have a surfboard immediately by him:

Speak with this gentleman and he will tell you how he and Lapras used to surf everywhere together. This will excite Eevee / Pikachu and make them want to learn Sea Skim. Complete the remainder of the cutscenes and you will learn this technique.

Once obtained you are free to approach any water that is “surfable” and use the sea skim technique to catch water Pokemon or progress in the game.
