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.

November at Preciosa offers surfable conditions with a moderate average swell height of **1.3m** and a decent period of **9.4s**, suggesting mostly clean, organized waves. The swell is predominantly **NE to ENE**, with the highest frequency of rideable waves (1-2.5m) coming from these directions—**NE (26%)**, **ENE (22%)**, and **NNE (15%)**. Smaller contributions from **NNW** and **N** provide occasional variation. Waves in the 1-1.5m range are most common, ideal for intermediate surfers, while bigger sets (1.5-2.5m) appear often enough to challenge advanced riders. Wind conditions are a mixed bag: **28% of the time**, winds are favorable (typically light offshore or sideshore E to ENE breezes under 20kph). However, **E and ENE winds (20-30kph)** occur ~14% of the time, potentially creating chop. Stronger winds (>20kph) from E/ESE are occasional but manageable. Overall, November delivers consistent, mid-sized NE swells with enough clean windows for good sessions, though wind variability requires selective timing. Best for surfers comfortable with chest-high to overhead waves and shifting conditions.
