Playa Matapalo - surf spot statistics

Playa Matapalo in Costa Rica offers consistent surf year-round, with ground swells dominating nearly every month (92-100% occurrence), ensuring reliable wave energy. The swell size averages 1.0-1.1m in the early and late months (January-March, December) but builds to 1.4m from May through November, peaking in the mid-year period. Wind conditions show a clear seasonal split: January-April has less favorable winds (38-47% good conditions), while May-December sees significant improvement, with the best winds from June to September (71-75% good conditions). The sweet spot for surfers is between May and November, combining larger swells (1.3-1.4m) and offshore-friendly winds (63-75% favorable). June through September stands out as prime time—consistent 1.4m ground swells and 71-75% clean wind days create ideal surfing conditions. Early season (January-April) still delivers waves, but smaller swells and onshore winds reduce quality. October-November offers a strong compromise with solid swell size and 64-67% good winds before dropping slightly in December. Advanced surfers targeting bigger, cleaner waves should prioritize the mid-year window, though Matapalo remains surfable year-round thanks to its high groundswell consistency and limited flat spells.
