Preciosa - surf spot statistics

Best Surf Season (October - April)

The North Atlantic winter storm track takes aim at the Caribbean, sending consistent pulses of northern swell directly toward Preciosa. During these months, the bulk of the swell arrives from the NNE, NE, and NNW quadrants, yielding the largest and most powerful waves of the year. Average heights hover around 1.6-1.7m, with periods in the 9-9.5s range, producing solid, punchy surf. However, the trade winds often blow from the east and southeast, creating side-shore or light onshore conditions. The magic happens when a cold front pushes through, shifting winds to the south, southwest, or west-southwest, delivering glassy offshore conditions on a clean groundswell. These windows are rare but can produce epic, long-period waves. October and November stand out as the peak months due to a better balance of swell size and favorable wind frequency.

Fair Surf Season (May & September)

May and September serve as transitional months. The winter storm track begins to weaken in May, while September sees the early signs of its return. Swell direction shifts toward the ENE and E, which are less ideal angles for Preciosa, resulting in smaller, cleaner waves on average. Heights drop to around 1.3m and periods shorten into the 8-8.5s range. The trade winds become more variable, and a higher percentage of light and offshore winds (38-50% ideal) makes for fun, rippable conditions when the swell lines up. Expect fun-sized waves with occasional pumping pulses from decaying tropical systems or early winter storms.

Low Surf Season (June - August)

June through August marks the low point of the surf calendar at Preciosa. The North Atlantic storm track retreats, leaving the Caribbean dominated by the easterly trade wind swell. Swell directions are overwhelmingly from the E and ENE (87-97% of all wave energy), which wrap in with a poor angle for the NNE-facing beach. Average wave heights dip to 1.2-1.3m and periods fall to 7.3-7.5s, resulting in small, choppy and often weak surf. Winds are mostly from the east and southeast, blowing side-shore to onshore, further degrading quality. The only saving grace is the higher frequency of light winds and occasional offshore days from the south (ideal wind 33-42% of the time), but these seldom coincide with any significant swell. Tropical waves and distant hurricanes can produce short-lived pulses, but overall, expect groveling conditions with rare openings for a fun session.

July: Summer Slump

July hits the lowest point of the year for swell quality. Average height is 1.3m (barely), but period is a lackluster 7.3s. A staggering 87.1% of swell comes from due east, with only 0.3% from the NE—the only favorable quadrant with any presence. Most waves are in the 1-1.5m range (65.4%), with small amounts of bigger sets. Winds are dominated by the E (32.4%) and ESE (45.7%), but ideal offshore conditions occur 33% of the time. The combination of weak, short-period east swell and side-shore winds makes for predominantly choppy, weak surf. Only when a tropical system passes nearby does the size jump, but those days are rare. Patience is a virtue; focus on the early mornings with light offshore breezes for the best chance at a fun, rippable wave.
