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.

March: Transition Fizzle

March sees the tail end of winter's influence, with average swell heights still 0.5m but period dropping further to 4.4s. Swell from the optimal NNW direction declines to 13.3%, while ENE swell increases to 33.4% – mostly under 1m. The easterly trade winds strengthen, with E and ENE accounting for 42.6% of observations, often at 20-40 kph. Southerly offshore winds are a mere 5.1% combined. The surf becomes increasingly inconsistent and blown out. Late-month cold fronts can deliver a brief spike in NW swell, but it's usually accompanied by onshore north winds, ruining the shape. Not a month to plan a trip around.
