La Boya - surf spot statistics

La Boya in the Dominican Republic is primarily a windswell-driven spot, with ground swell being practically non-existent throughout the year. The best months for surfers are generally from May to August, when windswell frequency is highest—peaking in June at 95%. During this period, mean swell size hovers around 0.7-0.8m, offering rideable conditions, albeit on the smaller side. However, wind conditions are consistently poor, with favorable winds occurring only 2-7% of the time across all months, making cross-onshore or onshore winds the dominant factor. September through November sees a drop in windswell frequency, dipping as low as 58%, while no-swell days increase, particularly in October and November (42%). Swell size remains modest year-round, rarely exceeding 0.8m, which limits performance surfing. Overall, while La Boya provides consistent small waves, the lack of ground swell and persistently poor wind conditions make it a spot better suited for beginners or those looking for relaxed sessions rather than high-performance surfing. Winter months (December-February) see slightly cleaner wind days (2-3%), but swell consistency and size remain limiting factors. For the most reliable surf, target the mid-year months, but be prepared for less-than-ideal wind.

In September, La Boya experiences mostly small to moderate surf, with an average swell height of 0.6m and a period of 6.1s, indicating generally weak to fair wave energy. The predominant swell direction is from the SE (70.17% of waves under 2.5m), providing the most rideable conditions, while SSE and ESE swells contribute to a mix of smaller waves. The wind is less favorable, with only 6% of days offering ideal conditions (likely light offshore or cross-offshore breezes). The dominant winds come from the NE to E quadrant at 10-20kph (29.27% cumulative probability), which can create choppy or side-shore conditions, reducing wave quality. South swells (S, SSW, SW) are minimal but occasionally produce slightly larger waves (up to 2.5m in rare cases). Advanced surfers may find occasional clean, knee-to-chest-high waves when SE swells align with lighter winds, but overall, expect inconsistent surf with frequent onshore wind interference. Wind speeds above 20kph (mostly NE-E) occur 15.36% of the time, further degrading conditions.
