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.

June at Playa Hermosa offers fairly consistent surf conditions with a solid mix of rideable swells. The average swell height is 1.3m, with a strong period of 14.7s, indicating well-spaced, powerful waves—ideal for experienced surfers. Most swells come from the SSW direction (51.84% in the 1-1.5m range), providing nicely angled waves that hold shape. The SW and S directions also contribute, with some bigger sets up to 2.5m. Wind conditions are variable, but only 31% of the time are they truly ideal (likely light offshore or cross-shore). The predominant winds are SSW to SW, often in the 10-20kph range, which can create some chop, especially in the afternoons. Early mornings typically have cleaner conditions. Overall, June delivers consistent, punchy waves with solid energy, though wind quality is hit or miss—best surfed at dawn or when winds are light.
