Sun Beach - surf spot statistics

Best Surf Season (October - March)

While Sun Beach never sees epic conditions, the winter months from October through March offer the most potential. The North Atlantic storm track shifts south, sending occasional pulses of NNW and NW swell towards Cuba. These swells, though usually short-period and small (averaging around 0.5m), can produce rideable waves in the 0.5-1m range, especially from the NNW direction which is directly in the spot's window. However, the trade winds dominate, blowing consistently from the east and northeast, creating onshore or cross-shore conditions that chop up the wave faces. Offshore winds from the south and southwest are extremely rare, making clean, glassy sessions a true gift. Overall, it's a 'best of a bad bunch' scenario.

Fair Surf Season (April - September)

The summer months mark the low point of the year at Sun Beach. The easterly trade winds strengthen, and the swell window shuts down as the Atlantic storm activity wanes. Swell heights drop to an average of 0.3-0.4m with periods under 4 seconds, resulting in mostly flat, choppy conditions. The rare glimpse of rideable surf comes from brief pulses of ENE windswell, but these are short-lived and blown out by the persistent onshore flow. This is definitely the time to explore other activities or travel to more exposed spots.

November: Building Hype

November delivers the most consistent swell of the year, with average height at 0.5m and period 4.9s – the highest of any month. Swell from the NE jumps to 31.9%, with 15.0% in the 0.5-1m range and 2.0% at 1-1.5m. ENE swell remains a factor (29.0%), but NNW swell edges up to 9.5%, including 4.1% in the 0.5-1m range. Wind is still primarily from the E and ENE (combined 50.7%), often at 20-40 kph. Offshore wind from the south is still scarce (combined 2.7%). Despite the poor wind climatology, the increased swell frequency means more opportunities. Cold fronts and developing low-pressure systems in the Atlantic send pulses of NE swell that wrap into the spot. Most waves are choppy, but if a front clears out the trades, we can see glassy, shoulder-high peaks. It's the best month for gambling on a session.
