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 January, Yumuri, Cuba, offers surfable conditions with an average swell height of 1.1m and a decent period of 8.0s, providing some consistency for intermediate surfers. The dominant swell directions are ENE and E, which contribute the most rideable waves, particularly in the 0.5-1.5m range (around 12-15% occurrence for ENE swells). While larger swells (1.5-2.5m) do occur, they are less frequent, limiting opportunities for advanced surfers seeking bigger waves. Wind conditions are less favorable, with only 13% of the time being ideal—typically when lighter ENE or NE winds prevail. Stronger winds (20-30kph) from ENE are common, potentially creating choppy conditions. Overall, January delivers modest but inconsistent surf, best suited for surfers comfortable with smaller, mid-period waves and occasional wind-affected sessions.
