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 March, Yumuri experiences a mixed bag of surf conditions with an average swell height of 1.0m and a decent period of 8.0s, offering manageable but often small waves. The majority of swells come from the northeast to east-northeast, with ENE swells being the most frequent and delivering the best energy (14.14% of waves in the 1-1.5m range, 7.16% in the 1.5-2m range). Smaller contributions from NNE and E directions provide some variety, though larger waves (over 2m) are rare (only 1.38% from ENE). Wind conditions are less favorable, with only 14% of winds being ideal for surfing—typically light offshore or cross-offshore breezes. Stronger onshore winds from ENE and NE (often 10-30kph) can create chop, reducing wave quality. Overall, March offers rideable waves for intermediates, with the best chances on clean ENE swells when winds cooperate, but expect inconsistency and occasional wind-affected conditions. Advanced surfers may find limited days with punchier 1.5-2m waves, especially mid-month.
