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%.

December at La Setenta tends to offer relatively small but rideable conditions, with an average swell height of 0.7m and a period of 5.8s. The swell is predominantly NE to NW, with the best size and consistency coming from the NE (13.27% at 0.5-1m, 2.17% at 1-1.5m) and NW (6.18% at 0.5-1m, 4.11% at 1-1.5m). Larger swells (1.5m+) are rare but most likely from NW, WNW, and NNE directions, though they remain infrequent. The wind is a limiting factor—only 19% of the time does it align favorably for surfing. The most common winds are ENE to E (10-20kph), which can create chop, especially when stronger (20-30kph). Offshore or light cross-shore winds are rare, mostly occurring with NNW or W directions at lower speeds (0-10kph). Overall, expect small, manageable waves best suited for longboarders or relaxed sessions, with occasional mid-sized days when NW swells push through. Wind conditions will often dictate session quality, so timing around lighter or favorable winds is key.
