In August, Playa Jaco receives consistent swells with an average height of 1.3m and a solid period of 14.5s, indicating well-organized, powerful waves. The swell direction is predominantly from the SSW (71.3% of waves between 1-2.5m), providing clean, rideable conditions suited for intermediate to advanced surfers.
