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%.

May at La Setenta, Cuba, offers generally small but rideable waves, with an average swell height of 0.4m and a period of 4.7s. The swell is predominantly from the NE to ENE direction, contributing the largest portion of waves in the 0.5-1.5m range, though most are below 1m (NE: 25.17% at 0-0.5m, 16.15% at 0.5-1m). Larger swells (1.5m+) are rare, making this spot better suited for longboarding or beginner-intermediate surfers during this month. Wind conditions are less favorable, with only 9% of the time being ideal for surfing. The prevailing winds come from the E-ENE (14-20kph range), which can create choppy or cross-shore conditions, limiting clean surf sessions. Offshore or light winds are infrequent, so patience and timing are key for scoring the best conditions. Overall, expect small, weak waves with inconsistent wind support in May—best for relaxed sessions rather than high-performance surfing.
