In my unscientific opinion, I think there is some skills overlap with skateboarding, surfing, and snowboarding. They all put your body at a 90 degree angle to the direction you're heading and you have to adjust your center of gravity over the board to turn. So it's very possible your skateboarding skills will help you learn faster than people who don't surf and skateboard.
