Playa Hermosa - surf spot statistics

Playa Hermosa, Costa Rica, is a consistent year-round surf destination with a strong reliance on ground swells, which dominate nearly every month (90%+ frequency). The best conditions typically occur from December to March when the swell consistency remains high (96–100% ground swells) and wind conditions are most favorable, with good winds occurring 47–62% of the time. During this period, the average swell size ranges from 0.9 to 1.0 meters, offering clean, surfable waves with minimal wind interference. April and November serve as transitional months, still offering reliable ground swells (100% and 93% respectively) but with increasing onshore winds reducing quality, particularly in April where bad winds occur 61% of the time. From May to October, wave heights increase slightly (1.3m average), but wind conditions deteriorate significantly, with bad winds dominating 65–69% of the time, making sessions more challenging due to cross-onshore or onshore winds. September and October see a slight rise in wind swell contributions (6–8%), but this does little to offset the poorer wind outlook. Overall, the prime season for quality surfing at Playa Hermosa is during the Northern Hemisphere winter (December–March), when clean ground swells and manageable winds align most favorably. The rest of the year still provides consistent waves, but wind conditions become increasingly problematic, reducing the number of ideal surfing days.

In January, Playa Hermosa offers consistent surf conditions with an average swell height of 0.9m and a solid 13.7s period, indicating well-spaced, powerful waves. The swell direction is predominantly from the SSW (56.76% of waves in the 0.5-1m range, 15.37% in 1-1.5m), ensuring clean, rideable waves with good shape. Wind conditions are favorable 62% of the time, mostly light to moderate (0-20kph) from the NNE, NE, and SW directions, which typically provide offshore or sideshore effects. While larger swells (1.5m+) are rare (0.2% occurrence), the spot thrives on mid-sized waves with excellent energy due to the long period. Expect peaky, powerful beachbreak waves—ideal for experienced surfers looking for hollow sections and fast rides. Minor NE wind chop may occasionally interfere, but overall, January delivers high-quality surf at Hermosa.
