Sun Beach seasonal overview

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.

Conditions at Sun Beach in April

April: The Drop-Off

April marks a clear downturn as average swell height slips to 0.4m and period to 4.1s. The swell window narrows dramatically: ENE dominates at 38.5%, almost entirely under 0.5m. NNW swell plummets to 12.9% with only 3.2% in the 0.5-1m range. Wind remains relentless from the east, with E and ENE totaling 45.1%, and speeds frequently in the 20-30 kph range. Ideal offshore winds from the south are virtually nonexistent (combined 4.6%). The result is a month of mostly flat, choppy conditions. Only a stray tropical wave or distant cold front can stir up ankle-high slop. Leave the board at home.
