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.

In September, Playa Matapalo offers solid surf conditions with a consistent swell averaging 1.4m and a strong period of 14.4s, ensuring well-formed, powerful waves. The swell direction is predominantly from the SSW (74%) and SW (11%), with heights mainly in the 1-2.5m range, providing clean, rideable waves for intermediate to advanced surfers. The wind is favorable 75% of the time, mostly light to moderate (0-20kph) and blowing from the W, WSW, and SW—ideal for keeping the surface clean without creating chop. While larger sets (2-2.5m) are less frequent, the combination of consistent swell, long period, and offshore-friendly winds makes September a reliable month for quality sessions, especially when the SSW energy peaks. Expect some variation in size, but overall, it’s a prime time for surfers comfortable with punchy beachbreak conditions.
