Sosua - surf spot statistics

Best Surf Season (December - March)

During the winter months, the North Atlantic delivers consistent medium-period swell to the Dominican Republic's north coast. Average wave heights hover around 1.5-1.6m with periods averaging 9.3-9.4s, providing punchy, rideable waves at Sosua. The dominant swell direction is from the ENE and NE, which, while not perfectly aligned with the beach's north-facing exposure, still wrap nicely into the bay. However, onshore winds from the north can be problematic, with ideal wind conditions occurring only about 29-37% of the time. When the stars align and a southerly breeze cleans up the faces, the waves can be really fun, with some sets reaching the 1.5-2.5m range.

Fair Surf Season (April - May & October - November)

These transitional months see a dip in swell size and period but an improvement in wind conditions. April and May average 1.2-1.3m with periods dropping to 8.1-8.9s, while October and November offer slightly better size at 1.2-1.5m and periods around 9.1-9.3s. The wind becomes more favorable, with ideal percentages climbing to 35-56%, as the trade winds shift more easterly and southeasterly, offering cleaner conditions. Swell energy still comes primarily from the ENE and NE, delivering workable waves for shortboards and fun-guns. Occasional pulses from the north can deliver peaky conditions.

Low Surf Season (June - September)

Summer brings the smallest and weakest surf of the year to Sosua. Average wave heights drop to 1.1-1.2m with periods as low as 7.2-8.8s, resulting in choppy, underpowered waves. The swell direction becomes almost exclusively from the E and ENE, making it difficult for the north-facing beach to capture any significant energy. On the bright side, wind conditions are at their best, with 39-58% ideal conditions as the easterly trades blow side-offshore, keeping the surface glassy. This is a great time for longboards, SUPs, and beginners looking for small, clean waves, but don't expect any pumping surf.

August: Slight Uptick, Still Small

August sees a marginal improvement with 1.1m height and 7.4s period. Swell direction shifts a bit more east-northeast: ENE at 39.3%, E at 55.5%, still dominated by short-period windswell. Northern swell is minimal (NNE at 0.7%). Wind conditions are the best of the year: ideal at 47%, with ESE (39.5%) and E (28.4%) providing clean side-offshore flow. Onshore winds from the north are negligible. August is similar to July but with slightly more variety from ENE. Expect small, clean waves perfect for longboards and fun shapes. The occasional pulse from a hurricane passing well to the north can produce a fun waist-high day, but generally it remains small.
