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.

October in Playa Santa Teresa offers solid surf conditions, with a predominant swell from the SSW and SW directions, making up the majority of wave activity. The average swell height is 1.4m with a long-period 14.3s interval, indicating consistent, well-spaced waves that provide good power and shape for intermediate to advanced surfers. Most waves fall in the 1-1.5m and 1.5-2m range (37% and 17.3% from SSW, respectively), with some larger sets up to 2.5m when conditions align. The wind is favorable for surfing 39% of the time, predominantly light to moderate (under 20kph) from the south and southwest, helping to maintain clean wave faces. However, stronger winds can occasionally disrupt conditions, particularly when blowing from the west or WSW. Overall, October delivers reliable surf with good size and power, though wind variations may require careful timing for optimal sessions.
