The ever changing river

What is a River Mouth?

A river mouth is where the journey of a river ends and vast expanse of the ocean begins, an estuary is typically a transition area that exists before a river reaches its final destination at a saltwater location. This meeting point is a somewhat enclosed body of water that stands as a dynamic transition zone. Estuaries, one of nature’s most intricate and ever-changing phenomena, are sites of significant processes that have substantial impacts on both their local environments and our surfing experiences.

Some of the most perfect, long, and hollow waves exist at the mouths of rivers, thanks to sandbars created and maintained by the river, the tide, and the waves.

River mouth sandbars are never in the same place nor totally fixed in one spot. They exist in a state of fluid equilibrium, maintaining more or less the same size and shape over the long term, but varying in the short term according to conditions.

The Tamarindo River mouth is no exception, and many long-term Tamarindo locals have seen this river change drastically over the 30 or so years that surfing has been popular in Costa Rica. It has produced some of the best waves and barrels ever seen on this stretch of coastline we call home

The best years of 2014 up till around 2016 the river flowed straight and hard making a defined line between Tamarindo and Playa Grande, with the wave breaking deep to the north in the river.

A rifling right-hander with intimidating sections could literally break boards and necks, but regardless of the size, the wave would follow the same course. Whether it was 3ft or 10ft, it would just reel like something out of a movie. I was in heaven, we were all in heaven. Then, for no reason other than the cycle of weather, we lost so much. The wave itself, 70% of the green zone that fringed Witchs Rock Surf Camp before you stood barefoot on the sand, and even the lifeguard tower… this hit us all quite hard as we had invested time, resources, sweat, and training to make that project happen.

We recruited as many staff members as we could to volunteer to save the tower. We made rock cages, dug out a trench in the pouring rain, only to be defeated and stand there powerless as the tower simply washed away with the tide.

But looking back at all the great sessions that we all scored out on the sand and sediment-loaded bars, the year we lost the most, I feel I gained the most. The realization that nothing is forever, life changes, and you can ask us all, has the river been the same since that time? The answer is NO. Will it ever come back? We hope so!

You can’t beat Mother Nature and you can’t fight the wind and the waves, but as sure as stoke we can surf them, so that’s what we do, we look for the best in life. The Lifeguard tower is back and better than ever. Now, learning from our past, the Lifeguard tower is on skis, allowing us to move it as needed. In surfing, as in life, appreciate what you have, as it will change. Take it while it’s here, as it won’t be here forever and accept changes as they are coming.

Yes — Tamarindo is considered one of the safest beach towns in Costa Rica for tourists. Most incidents involve petty theft, while violent crime affecting visitors is rare. With basic precautions, it’s a very safe destination for surfers, families, and solo travelers. Costa Rica has long been known as one of the most stable, welcoming countries in Latin America. Yet online discussions, headlines, and occasional embassy alerts often raise the same question for travelers: Is Costa Rica safe — and is Tamarindo safe to visit? This guide separates facts from perception , explains why safety concerns are often misunderstood , and looks specifically at Tamarindo through the lens that actually matters: the real experience of travelers on the ground . At Witch’s Rock Surf Camp, we’ve hosted thousands of travelers, families, and solo surfers in Tamarindo since 2001 — giving us a real, on-the-ground perspective of what safety actually looks like here. Understanding Safety the Right Way: Tourist Reality vs Headlines When people search “Is Costa Rica safe?”, they are often shown national crime statistics without context. This creates confusion. Here’s the key point: 👉 Tourist safety is not measured by national crime averages — it’s measured by what happens in tourist areas. National crime data includes: Drug-trafficking activity Gang-related violence Urban neighborhoods far from tourism Domestic and local disputes unrelated to visitors These factors do not reflect the reality of beach towns, surf destinations, or established tourist communities like Tamarindo. The same logic applies everywhere: Crime in parts of Los Angeles does not define safety in Malibu Crime in New York City does not define safety in the Hamptons Crime in Mexico City does not define safety in Cozumel Tamarindo must be evaluated as a tourist destination — not as a national statistic. Is Tamarindo Safe Compared to Other Popular Destinations? When Tamarindo is compared properly — city to city, destination to destination — the picture becomes clear.

Witch’s Rock, the wave from which we derive our namesake, popularized by The Endless Summer II most definitely lives up to the hype. If you’ve seen the movie, you know what this wave can do during a swell. Simply put, it’s a leg burning barrel. Witch’s Rock handles swell very well, it gets big, and it gets hollow. What
