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.

November at Playa Hermosa delivers consistent surf with an average swell height of 1.1m and a solid period of 13.9s, indicating powerful, well-spaced waves ideal for intermediate to advanced surfers. The majority of swells come from the SSW direction (52.8% between 1-1.5m), providing clean, lined-up waves with occasional larger sets up to 2.5m (6.13% at 1.5-2m). Wind conditions are surfable 46% of the time, predominantly light offshore or cross-shore (NNE to NE at 0-20kph), but mornings often see the cleanest sessions before afternoon breezes pick up. While smaller days (0.5-1m) occur roughly 24% of the time, the spot frequently offers punchy, overhead waves with strong shoulders—perfect for turns and barrels when the tide and wind align. Watch for SW winds (4.35% at 10-20kph), which can occasionally create chop, but overall, November is a prime month here with reliable energy and manageable conditions.
