Cayo Coco • Surf Spot Statistics

Best Surf Season (November - February)

Cayo Coco is a north-facing Atlantic beach on Cuba's northern coast, and its surf year is tied to the wintertime battle between the North Atlantic storm track and the relentless Caribbean trade winds. From November through February, the Azores High weakens and the NAO frequently slips into a negative or neutral phase, shunting cold fronts and low-pressure systems farther south toward the Gulf of Mexico and the Straits of Florida. Those fronts are the main source of clean, N, NNW and NW swell for this stretch of coast. The average surf height peeks at 2.6ft (0.8m), and the optimal northerly quadrant accounts for its highest seasonal share of the swell spectrum. Still, the average wave period remains near 3.4s, so most of the energy is short-period windswell; the surface only cleans up on the rare days when winds swing into the S/SSW/SW quadrant after a front passes. Those ideal offshore days are scarce, showing up just 1-2% of the time, but when they line up with a fresh NNW pulse, Cayo Coco can deliver surprisingly fun, groomed peaks in the 2-3ft (0.6-0.9m) range.

Fair Surf Season (March - April & October)

March and April offer the tail end of the frontal season, when the North Atlantic is still active enough to send occasional N/NNW swell windows toward Cuba. The trade winds are becoming stronger and the water is already warm, but the consistency is lower than in winter, with optimal-direction swell slipping to around 8-11% of the spectrum. October is the other wildcard: the fall transition and developing Atlantic hurricane season can throw tropical-origin swell into the mix, and the first cold fronts of the season begin to probe the subtropics. These months are far from consistent, but they do produce more usable windows than the dead summer months, and the air and water temperatures remain sweatshirt-free.

Low Surf Season (May - September)

From May through September, the North Atlantic subtropical high builds back in and the trade-wind machine locks onto Cayo Coco. Easterly and east-northeasterly winds dominate the wind rose, often blowing 20-40kph, and the swell spectrum becomes overwhelmingly short-period E/ENE windswell. Average wave heights drop to 1.6-2.0ft (0.5-0.6m) with periods around 3s, and the optimal northerly swell directions shrink to nearly zero by midsummer. This is the low season for surf: the beach is warm, the water temperature climbs to 28-29°C, but the ocean is mostly lumpy, chopped-up trade-wind bump. The one exception is tropical cyclone season, when a passing hurricane or major low to the north or northeast can briefly fire up disorganized but powerful N/NW swell across the normally sleepy north shore.
