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.

In February, Esterillos offers consistent surf conditions with an average swell height of 0.9m and a solid 14.0s period, producing well-spaced, clean waves. The primary swell direction is from the SSW (65.5% of waves in the 0.5-1m range, 15.42% in 1-1.5m), ensuring favorable shape and rideability. Wind conditions are surf-friendly 58% of the time, with light to moderate breezes predominantly from the NNE to NE (around 17-20kph in the 10-20kph range) and offshore tendencies. However, occasional stronger winds from the NE or SSW can create choppier conditions. Waves are generally in the waist-to-shoulder-high range, ideal for intermediate to advanced surfers, with rare larger sets. Expect clean, rideable surf on most days, especially during morning sessions when winds are lighter.
