Playa Santa Teresa - surf spot statistics

Playa Santa Teresa, Costa Rica, is a consistent surf destination with year-round swell activity, primarily dominated by powerful ground swells. The best months for surfing are typically from November to April, when conditions are most favorable. During this period, ground swells are predominant (92-100% occurrence), and wind conditions improve, especially in December and January, where good wind conditions reach around 60%. Swell size during these months averages between 0.9m to 1.2m, offering manageable yet fun waves suitable for intermediate to advanced surfers. The peak swell size occurs from May to October, averaging 1.4-1.5m, but this period also brings more frequent onshore winds, with bad wind conditions peaking at 60-64% from April to September. March and April see the largest swells of the high season (1.1-1.2m), but wind quality deteriorates, making late November to February the optimal window—great swell consistency, decent wind, and slightly smaller, cleaner waves. If you prefer bigger, more powerful surf and can handle less ideal winds, September offers the largest swells (1.5m), though wind conditions are poor (64% bad winds). For surfers prioritizing clean conditions, December and January strike the best balance between swell size, consistency, and favorable winds.

In March, Playa Santa Teresa offers consistent surf conditions with an average swell height of 1.1m and a solid 14.5s period, ensuring well-formed, powerful waves. The swell direction is predominantly from the SSW (67.5% of waves in the 0.5-2m range), providing clean, rideable waves that align well with the beach. Wind conditions are favorable for surfing 46% of the time, with light to moderate breezes most common. However, stronger winds from the NNE and SSW can occasionally create choppy conditions. The best sessions typically occur when winds are light offshore or sideshore, allowing the long-period swells to groom into clean, hollow waves ideal for intermediate to advanced surfers. Expect peaky, fast-breaking waves with good shape, especially on mid-to-high tides when the swell energy is optimally focused.
