People have drowned surfing Tamrindo beach..At Negra where the main wave breaks, the water is around 20 ft deep. The wave also collapses in a uniform fashion and only will close out towards the end of a long section. I haven't seen the break perfectly clean. Hopefully I can catch a good swell there in the future.
I cut my head open surfing there. Not sure how it happened exactly, but I caught some rocks right above my eyebrow and chummed the water a bit. I agree that it didn't feel dangerous at all...I was being pretty reckless and think it was more my own fault than anything.
