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.

December at Yumuri, Cuba, offers generally manageable surf conditions with an average swell height of 1.1m and a solid period of 7.8s, indicating decent energy in the waves. The most consistent swell directions come from the ENE, NE, and E, with ENE delivering the largest waves—17.24% of the time in the 1-1.5m range and 10.65% in the 1.5-2m range. Smaller but frequent swells from NE and E contribute to rideable conditions, though the swell window is narrow, with virtually no energy from southern or western directions. Wind conditions are less favorable, with only 11% of days offering ideal offshore or light cross-shore winds. The dominant winds are ENE and NE, often blowing 10-30kph, which can create choppy or textured surfaces, especially when combined with the prevailing swell direction. Surfers should expect a mix of clean and messy sessions, prioritizing early mornings when winds are lighter. The spot works best on ENE swells with periods above 8s and light wind windows—experienced surfers will find the most opportunities, but consistency is moderate.
