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.

In July, Yumuri typically experiences a swell averaging 1.0m with a period of 6.9s, offering rideable but generally small to mid-sized waves. The primary swell direction is from the east (E and ENE), with the majority of waves (over 70%) falling in the 0.5–1.5m range and occasionally reaching 2m+. Larger swells (over 1.5m) occur around 6% of the time, providing more powerful conditions for experienced surfers. Wind conditions are less favorable, with only 20% of days offering ideal offshore or light cross-shore breezes. The prevailing winds blow from the east to northeast (ENE-E) at 10–30kph, which can create choppy or onshore conditions. Surfers should watch for rare clean days when winds shift lighter or more cross-shore. Overall, July delivers consistent but modest waves with variable wind challenges—best suited for intermediate surfers when conditions align.
