About
Las Gramas is an exposed sand-bar surf break near San Antonio (Chilca area) known for very consistent, world-class wave quality. It’s a powerful, ledgey setup that produces rideable waves on more than 150 days per year, with swell that typically starts working around 1.5–2 meters and can hold up to 3 meters and above. The wave breaks both left and right and is described as performing well at all tides, with falling tide specifically noted as favorable. Surf conditions are not for casual entries: the spot is repeatedly characterized as suitable for experienced surfers only, with hazards including rips/closeouts and strong currents during larger swells. Takeoffs are described as ledgey, and the combination of powerful wave face and current effects means conditions can tighten quickly when swell increases. If you’re going, plan around crowding and space—weekday and weekend crowding are both described as common. Access is a major part of planning. Entry is described as being via Puerto Viejo, with restricted/private access through gated or residential areas and limited/parking options. A car is needed, and 4x4 access is recommended for special beach access scenarios, while walking access to the lineup is reported as instant once you reach the correct access point. Wind-wise, the spot is associated with very consistent wind patterns along the San Antonio coast, and performance is described as best with light offshore or cross-shore winds, especially offshore from east-southeast. For safety planning, rescue/lifeguard presence is reported as none at the spot level, while regional rescue availability is described as limited—so rely on your own readiness and local emergency planning.
