  description: Playa Maderas is Nicaragua's most beloved intermediate wave—a fun beach break near San Juan del Sur that has become the heart of the country's growing surf scene. The wave offers consistent left and right peaks that work for all skill levels, from beginners finding their feet to experienced surfers looking for playful sessions. The vibe here is pure Central American warmth: sunset sessions, beachfront bars, and a community of international travelers who've discovered Nicaragua's incredible value proposition. When the southwest swells pump from April through October, Maderas delivers daily surfable conditions at a fraction of Costa Rica's prices.
