La Setenta - surf spot statistics

La Setenta in Cuba is primarily a windswell-driven spot, with ground swells being practically nonexistent throughout the year. The best months for surfers are from October to December, when windswell frequency peaks at 47-62%, and the mean swell size ranges between 0.6-0.7m. November stands out as the most consistent month, with the highest windswell probability (62%) and decent swell size (0.7m). December also offers favorable conditions, with 58% windswell occurrence and the best wind conditions of the year (19% good winds). January and February follow closely with moderate windswell activity (50-56%), though wind conditions remain poor (84-85% bad winds). From March onward, surfable conditions decline significantly, with windswell dropping below 50% and swell size diminishing. The summer months (June-September) are particularly flat, with minimal windswell (11-16%) and extremely unfavorable winds (93-96% bad winds). For surfers seeking rideable waves, the window from late autumn to early winter (October-December) is the optimal period, despite generally onshore winds. Spring and summer are best avoided due to lack of swell and poor wind alignment. Patience and a flexible schedule are key, as even in peak months, good wind days remain below 20%.

April at La Setenta, Cuba, offers generally small surf with an average swell height of 0.5m and a modest period of 5.2s. The predominant swell direction is from the NE to ENE, which accounts for most of the better-sized waves (0.5–1.5m). However, the majority of conditions fall in the 0–0.5m range, making it inconsistent for advanced surfers. The NW and NNW directions occasionally bring slightly larger waves (1.5–2.5m), but these are rare occurrences. Wind conditions are mostly Easterly (E–NE), which can be onshore or cross-shore, and only 11% of the time are they ideal for surfing. Stronger winds (20–30kph) are common from the ENE and E, which may further deteriorate wave quality. Overall, April is a low-energy month with infrequent rideable days—best suited for beginners or longboarders when conditions align. Seasoned surfers may find the spot underwhelming unless chasing rare NW swells or early morning sessions with lighter winds.
