Playa Marbella - surf spot statistics

Playa Marbella in Costa Rica offers consistent ground swell year-round, with virtually no wind swell or flat days, making it a reliable surf destination. The best months for surfers are January, February, November, and December, when excellent wind conditions prevail (96% in January and December, 89% in February, and 66% in November). During these months, the swell size averages around 1.1m to 1.4m, with clean offshore winds creating ideal surf. March sees good ground swell but a steep drop in favorable wind conditions (only 39%), making it less consistent. From April through October, wind conditions deteriorate significantly, with onshore winds dominating (up to 96% bad winds in July), though ground swell remains steady at 1.3m to 1.5m. Summer months (June-August) are particularly challenging due to strong onshore winds, despite consistent swell. For surfers prioritizing clean conditions, the winter months (December-February) and late autumn (November) are optimal, offering a perfect balance of swell consistency and favorable winds.

December at Playa Marbella, Costa Rica, offers excellent surfing conditions with consistent swell and favorable winds. The average swell height is 1.2m, paired with a strong period of 14.8s, producing well-organized, powerful waves ideal for intermediate to advanced surfers. The swell direction is predominantly from the SW and SSW, contributing to 19.98% and 31.96% of waves in the 1-1.5m range, respectively, ensuring clean, rideable conditions. Larger sets occasionally reach 1.5-2m, adding variety for more experienced riders. Wind conditions are highly favorable 96% of the time, with light to moderate speeds (mostly under 20kph) and directions primarily from the NE and ENE, which typically groom the waves without creating choppy surfaces. Offshore winds are rare but contribute to glassy perfection when they occur. This combination of solid swell energy, clean wave faces, and minimal wind disruption makes December a prime month for surfing at this spot.
