I am a decent snowboarder, will that make it easier to learn how to surf

in a way yes but you still need to learn how to catch the wave

no it wont, their almost complete opposites. surfing requires catching the wave and lots more balance because water isnt solid like hard compact snow. practice on small waves and gradualy learn to get better.keep it real by skateboarding and snowboarding bro.

Both activities require some good balance & flexibility. Beyond that, they r apples & oranges.
Surfing is an ocean sport, & requires ocean swimming skills. The ocean is not a pool, it has tricky rips, undertows, currents & big waves. After that, to be a 'real' surfer, u need to know surf etiquette.
Athletically speaking, u need to catch the wave, as opposed to having gravity start u off down hill. Catching the wave can be one of the hardest things to learn.
With all that said, snowboarding must be really cool (not for me, however, snow is something l only like to see on Christmas cards), & l am sure that the conditioning & balance skills developed snowboarding sure can not hurt.

yes, but surfing and snowboarding have different ways of moving the board. you will just have to get used to it. snowboarding uses back foot, surfing front foot.

This experience will give u the upper hand when learning to surf, although as stated above u will still need to learn how to catch a wave. Any previous board riding experience will always help with a new surfer.You will, however, need to work on ur upper body strength, to improve ur pop up onto the board as this needs to be one fluid motion. Your balance should be fairly strong on the board but u have to be ready for the changing surfaces in the wave, & so u will need to develop a different sort of balance to snowboarding.

Surfing, windsurfing, skateboarding, and snowboarding have just about the same maneuvers, however in surfing, trying to stand on the board is the tricky part, the rest is just as easy as a snowboard.

dont listen to anyone let me tell u..snowboarding & surfing totally different ..good snowboarder but surfing is hard because u have to fight the water.its harder 2 learn..& 2 actually get up on the surfboard .u will see

if you can ride half pipe, yeah

no, because its two totally different sports but do not get discouraged keep surfin bro.
