Esterillos - surf spot statistics

Esterillos in Costa Rica offers consistent surf year-round with predominantly ground swell, making it a reliable destination for surfers. The best months for optimal conditions are typically December through March. During this period, ground swell is dominant (96-100%), and good wind conditions are more frequent (58-63%), especially in December and January when winds are most favorable. Swell size remains manageable, averaging around 0.9-1.0m, providing fun, clean waves. April and November are transitional months, with slightly larger swells (1.1m) but fewer good wind days, making sessions more hit-or-miss. From May through October, swell size increases (1.3m), but the frequency of poor wind conditions rises significantly (59-67%), leading to choppier surf. September and October see the highest wind swell influence (6-8%), though ground swell remains dominant. Overall, mid to advanced surfers may still find good sessions year-round, but the dry season (December-March) delivers the most consistent and cleanest conditions with lighter winds and reliable waves.
