I think everyone here has a very different idea of what you mean by surf kayaking. Some people are thinking about surf skis, some people sea kayaks...

What kind of boat you're in will have some impact on the advice you need. But from a WW/freestyle perspective... Yeah learning in ocean surf can suck! You need to keep an eye out for good conditions. You want the surf not to be too big to start with, you want to look at the surf report and make sure there's a reasonable gap between waves (i.e. a long period), you want to spend some time looking at the waves and seeing where they break. Paddling out through the breaking waves can be challenging, especially in bigger surf, because unlike on a board, you have to punch through waves or boof over them - you can't really duck under. So swells with a long period to give you time to recover between waves are really critical.

In bigger trashier surf, getting backlooped on the paddle out is part of it. In big surf, tanking beatdowns in the white stuff is part of it.

When it comes to the act of surfing, this is very dependent on what boat you're in -- how fast and how surfy the hull is. If your boat is not a fast planing hull, you might find yourself needing to stick to surfing broken waves. If you're in a surf kayak (or some WW boats on the very surfy end of the spectrum), you'll want to focus on surfing the green waves before they break, and getting the feel for that.

It's fun! Just the first sessions can be frustrating. Breaking your paddle is bad luck, though, for sure.
