Cayo Coco - surf spot statistics

Best Surf Season (October - March)

Cayo Coco's north-facing coastline is a tricky proposition for surfers. The 'best' window falls between October and March, when the North Atlantic begins to stir. However, even during these months, the dominant swell direction remains from the E to ENE quadrant, generated by the persistent trade winds. This means the vast majority of waves arrive as short-period, messy windswell under onshore conditions. The true 'best' is relative: a slight increase in the frequency of N, NNO, and NNW swell pulses occurs as cold fronts sweep across the Gulf, offering rare windows of rideable, if still short-period, surf. Offshore wind from the S to SSW quadrant is exceedingly rare, with only 1-2% of the time being ideal. When the stars align, you can score small, punchy waves in the 0.5-1.5m range, but patience is paramount.

Fair Surf Season (April - May, September)

During April, May, and September, the trade wind regime tightens its grip. Swell heights drop slightly and periods remain in the choppy 3-second range. The N component of swell almost vanishes, leaving only weak E-ENE energy. While the wind patterns offer a marginal increase in S to SSW flow during these transition months, it's still less than 2% of the time. Surfable waves are rare and often below 0.5m. These months are best reserved for travel days or exploring other activities.

Low Surf Season (June - August)

Summer in Cayo Coco is a true surf desert. The average swell height plummets to 0.5-0.6m, and the wave period hovers around a dismal 3.0s. Swell direction is overwhelmingly from the East - over 60% in June and nearly 80% in July - which means the spot is completely shadowed. North quadrant swell is virtually non-existent. The wind blows relentlessly from the E-ESE, creating pure onshore chop. Offshore winds from the south are a statistical anomaly. Surfing is essentially not viable; this is the nadir of the yearly season.

October: The Season Begins to Stir

October marks the true beginning of the better season. Average swell height rises slightly to 0.6m, period to 3.1s. The most notable change is a significant increase in north quadrant swell: N through NNW now account for about 8% of the total, with some waves reaching 1-1.5m. ENE swell remains strong at 33.8%, but E swell drops to 26.6%. Wind patterns begin to shift: NE winds increase to 14.2%, and N winds to 2.4%, while E winds ease to 21.9%. Offshore south winds remain scarce (about 1-2%). The combination of more N swell and occasional cold fronts means there are a few days with small, short-period but clean waves – typically when a front passes and winds swing to the south behind it. It's not pumping, but it's the start of the window.
