Yumuri - surf spot statistics

Yumuri, Cuba, is a surf spot predominantly influenced by wind swells, with ground swells playing a minor role throughout the year. The best months for surfing are generally those with a higher likelihood of clean conditions and manageable swell size. September stands out as the most promising month, with 17% ground swell contribution—the highest of the year—and 23% good wind conditions, which is also the peak for favorable winds. While the mean swell size remains modest at 0.8m, the reduced wind swell dominance (68%) and an increase in ground swell make it a more reliable time for surfers. Late summer and early autumn (July to September) offer a slight improvement in wind conditions, though wind swells still dominate. The winter months (November to February) bring slightly larger swells (1.1m), but unfortunately, they coincide with the worst wind conditions, with bad winds occurring 85-89% of the time. Spring and early summer (April to June) see smaller swells and persistent wind swell influence, making them less ideal. Overall, September is the best month for surfing at Yumuri, offering a rare balance of decent swell composition and the least unfavorable winds, though even then, conditions remain challenging due to the spot's strong reliance on wind swells and often onshore winds. Surfers should be prepared for small to medium-sized waves and frequently less-than-ideal wind setups year-round.

June at Yumuri offers generally small but rideable conditions, with an average swell height of 0.8m and a decent period of 6.9s, suggesting somewhat organized waves. The best swells come from the E to ENE, making up the majority of rideable waves, particularly in the 0.5-1.5m range (peaking at 36.96% from the E in 0.5-1m). However, larger swells (over 1.5m) are rare, limiting the potential for more powerful sessions. Wind is a mixed bag: ENE and E winds dominate, but only 23% of the time are they ideal for surfing (likely lighter or offshore). Moderate onshore winds (10-30kph) prevail, which can create choppiness, especially when ENE—where nearly 30% of winds fall in the 10-30kph range. Experienced surfers can still find clean, smaller waves on lighter wind days, but don’t expect consistent, high-quality conditions. Overall, it’s a month for relaxed surfing rather than performance waves.
