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.

August: A Faint Pulse?

August sees a marginal increase in swell size from the depths of summer, but it's barely noticeable. Average height stays at 0.3m, period 3.2s. ENE swell still dominates at 54.4%, but a tiny fraction reaches 0.5-1m (2.9%). NNW swell inches up to 4.3%, still mostly below 0.5m. Wind patterns remain easterly: E (29.1%) and ENE (21.3%) are the primary players, often 10-30 kph. Offshore southerly winds are still rare (combined 5.0%). The first distant hurricanes or tropical storms can send low-energy, long-period swell towards Cuba, but it's typically too small and blocked by the Bahamas. Most days remain flat and choppy, but the slightest uptick in swell offers a glimmer of hope compared to June/July.
