Preciosa - surf spot statistics

Preciosa in the Dominican Republic offers surfable waves year-round, but the conditions vary significantly depending on the season. The best months for surfing are typically from November to March, when the swell consistency is higher and the mean wave size is more favorable, averaging around 1.3–1.4 meters. During these months, ground swell makes up 22–26% of the conditions, while wind swell dominates at 70–75%. However, wind conditions are less ideal, with bad onshore winds occurring 69–74% of the time, limiting the number of truly clean surf days. From April to October, the swell size decreases slightly, averaging 0.9–1.1 meters, with wind swell becoming even more dominant (up to 94% in July). The summer months (June–August) have the lowest ground swell influence (1–6%) and smaller waves, but the wind conditions improve, with good offshore or cross-shore winds occurring nearly 40–49% of the time. September stands out as a transition month with better wind conditions (49% good) and a slight uptick in ground swell (24%), making it a decent option for surfers looking for compromise between swell size and favorable winds. For advanced surfers seeking larger, more powerful waves, the winter months (December–February) are preferable despite the higher likelihood of onshore winds. Meanwhile, beginners or those prioritizing cleaner conditions may find late spring to early fall (May–September) more suitable due to lighter winds, even though the waves are smaller and less consistent. Overall, Preciosa works best when balancing swell size and wind direction, with the peak season favoring winter for size but requiring patience with wind conditions.

September at Preciosa delivers generally favorable surf conditions, with an average swell height of 1.0m and a solid period of 9.2s, ensuring well-formed, rideable waves. The dominant swell direction is ENE (24.99% of waves in the 0.5-1m range), followed by NE and E, providing consistent, clean energy with manageable shoulder-high waves. Smaller contributions from NNE and NNW offer occasional variation, though larger waves (1.5m+) are less frequent, peaking at around 3-5% occurrence from ENE and NE. Wind conditions are surfable 49% of the time, with the best scenario being light to moderate easterlies (10-20kph from E/ESE at ~36% combined). However, stronger trade winds (20-30kph) from E/ESE can occasionally create chop, especially mid-day. Expect a mix of playful, mid-period waves ideal for intermediate surfers, with rare bigger days offering more power. Early sessions often yield the cleanest conditions before winds pick up.
