It’s hard to say. We all have different schedules and I would suggest trying to surf around the same time as your friends. It is impossible for everyone so it’s best not to try too hard!
How do I become better at surfing?
Surfing is very much a skill but practice makes perfect so even if you don’t think you can get any better, just keep trying and eventually things will start coming together. There are loads of videos online that show these guys getting good over time but there are also many people who started out with nothing more than a board in their hands who now take on the world! If you want to learn how then this free video course could be right up your street: https://www.youtube.com/watch?v=yb1mTX6IgSs&feature=youtu.be
