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.

December at Preciosa offers consistent surf with an average swell height of 1.4m and a decent period of 9.6s, ensuring well-formed waves. The dominant swell directions are ENE and NE, contributing the most to rideable conditions—particularly in the 1-2.5m range, where over 30% of swells fall. Smaller days (0.5-1.5m) are frequent, but there’s still a solid chance of overhead waves, especially from NE/ENE angles. Wind conditions are crucial here—while offshore winds (ideal for surfing) occur only 26% of the time, the prevailing easterly trade winds (E/ENE) often bring onshore or cross-shore breezes in the 10-30kph range, which can create choppy conditions. Mornings tend to be cleaner before the winds pick up. Expect a mix of playful mid-sized waves and occasional punchier sets, best suited for intermediate to advanced surfers who can navigate variable wind effects. The lack of southerly swells keeps the lineup predictable, with most energy arriving from the northern quadrant. Patience and timing are key to scoring the best sessions.
