Thank you. That is what I was looking for. All the stories about "breaking waves" and couldn't figure out how to "forecast" at what height and period that would occur. Locals (San Francisco now, previously San Diego) say don't go out if the wind waves are square (6 X 6) or if they're predicted to be 4 feet or more. I had 6 foot wind waves at 8 seconds on the trip up from San Diego, not comfortable beating into but not scary or out of control either. Being new to cruising just trying to relate marine forecasts and bouy data to what it is going to be/feel like when ya get there. Thanks for the help.
