Cabo de San Antonio - surf spot statistics

Cabo de San Antonio, Cuba, is primarily a wind swell-dominated spot with minimal ground swell influence, as the data shows wind swell frequencies consistently above 70-98% year-round. The swell size is generally small, averaging 0.8–1.2m, peaking slightly in December and January. The best conditions for surfers align with periods of improved wind reliability, which occurs mostly from July to August when good wind conditions rise to 37-41%. However, even during these months, the swell remains modest, often below 1m. Outside this window, wind conditions are less favorable, with bad winds prevailing 73-79% of the time from January to June and September to December. Given the spot’s reliance on wind swells and smaller wave heights, intermediate surfers or those comfortable with softer conditions may find late summer (July-August) the most reliable, though expectations should be tempered—this isn’t a big-wave destination. The rest of the year offers more inconsistent winds and similarly small waves, making consistency challenging. For surfers prioritizing cleaner wind conditions over size, targeting July or August is advisable, but those seeking larger or more powerful swells may find the spot limiting year-round.

October at Cabo de San Antonio offers generally small but rideable surf, with an average swell height of 0.9m and a moderate period of 6.4s. The best waves come from the ESE, SE, and SSE directions, accounting for the majority of the larger swells (1m+), while NNE to ENE winds can create challenging cross-offshore conditions. Only 24% of the time does the wind align favorably for surfing, typically light to moderate from the E to SE range. Expect the most consistent waves in the 0.5-1.5m range, with occasional bigger sets up to 2.5m when SSE or SE swells combine with lighter winds. Wind speeds often hover around 10-30kph, making early mornings or protected sections the best bet. Overall, it's a hit-or-miss month—pack a groveler and watch for those less frequent, clean ESE pulses.
