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%.

January at La Setenta offers small to moderate surf conditions with an average swell height of 0.7m and a 5.8s period, indicating mostly weaker waves but occasional mid-period energy. The dominant swell directions come from the NE, ENE, NW, and NNW, with the NW and NNW quadrants producing the larger waves—4.13% of NW swells reach 1-1.5m, and 2.37% hit 1.5-2m. WNW and NNW also contribute, though larger waves (over 2m) are rare. Cross-shore or slightly offshore winds (NNE to ENE) prevail, but only 16% of winds are ideal for surfing, as moderate onshore NE/ENE winds (10-30kph) are common. For advanced surfers, the best sessions will come when NW/NNW swells combine with lighter NNE winds, offering cleaner peaks. Overall, expect smaller, sometimes weak surf, with occasional mid-sized days when wind aligns favorably. Not a high-performance month, but decent for relaxed sessions or longboarding.
