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 April, Yumuri offers relatively small but rideable surf, with an average swell height of 0.9m and a decent period of 7.7s—indicating mostly clean, organized waves. The predominant swell direction comes from ENE (combined 39.46% of waves in the 0.5-2.5m range), delivering the most consistent and larger waves, while NE and E also contribute. Smaller swells from N and NNE add occasional variety, though waves rarely exceed 1.5m. Wind conditions are less favorable, with only 13% of days providing ideal offshore or light cross-shore winds (mostly from W to NNW). However, ENE winds (14-20kph) are common and can create choppy conditions. For surfers, the best sessions will likely occur when ENE swells coincide with lighter winds from the west quadrant, offering shoulder-high peaks with reasonable shape. It’s a month for intermediate surfers, with patience required to score the cleaner days.
