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.

February: Consistent Swell, Challenging Winds

February mirrors January with an average swell height of 1.6m and a period of 9.3s, maintaining that punchy, rideable energy. Swell distribution is similar: ENE leads at 39.1%, followed by NE (21.7%) and NNE (13.7%). The northern component (N + NNW + NW) totals about 6.7%, slightly less than January. Onshore wind potential remains high – NNE and NE winds together account for 7.7% of observations, while the dominant wind directions are again E (28.1%) and ESE (27.7%), providing side-offshore flow. Ideal wind drops to 29%, the lowest of the winter months, indicating more frequent onshore or cross-onshore conditions. Despite the solid swell, expect less-than-perfect wave faces more often. Look for early morning windows when local thermal effects can tip the wind offshore.
