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.

July at Playa Hermosa offers consistent surf with an average swell height of 1.3m and a solid period of 14.4s, indicating powerful, well-spaced waves. The swell is predominantly from the SSW direction (49.7% of waves in the 1-1.5m range, 15.35% in 1.5-2m), providing clean, organized lines with occasional overhead sets (2-2.5m waves 1.54% of the time). SW swells (12.55% in 1-1.5m) contribute additional energy, ensuring rideable conditions nearly daily. Wind is a factor, with 35% of days offering ideal offshore or light cross-shore conditions—typically early mornings before thermal effects kick in. The dominant wind directions are SSW and SW (5-20kph range), which can create choppier afternoons but are often manageable due to the spot’s exposure. Expect peaky, powerful beachbreak waves suited for experienced surfers, with the best sessions occurring during morning glass-offs when wind is minimal. A reliable summer setup with occasional punchy days.
