The surf's up for Lewis Hamilton!

Lewis Hamilton indulged in a new off-season thrill, the five-time world champion initiating himself to the pleasures of surfing alongside American surf legend and friend Kelly Slater.

Hamilton, donned with a wet suit, was seen crashing the waves, the 11-time surfing world champion in tow, in a video posted on Instagram.

'New year, new sport, time to learn new things. Thank you #goat Kelly Slater for teaching me! That was rad,' he wrote.

Unsurprisingly, Hamilton looked quite adept on the board, although the venue looked chilly.

Check out the video of the F1 star' making a splash.
