Hello, welcome to the forums and to spearfishing! Here is a potentially helpful link for spearing regs

I'd suggest following the local laws and using your common sense. The laws on such things are often unwritten. Stay far enough away from swimmers and surfers that they don't feel threatened. Keep an eye on them, and if they seem uncomfortable, consider moving a bit further away. You may want to consult your local fish and game office if you have questions about specific locations.
Good luck, and welcome
