Sunzal - surf spot statistics

Sunzal, El Salvador, is a consistent year-round surf destination with reliable ground swells dominating the wave conditions nearly every month. The best months for surfing are typically from April to September when the mean swell size increases to around 1.2m–1.5m, offering more powerful and well-formed waves. April stands out with 100% ground swell and a decent 1.2m average size, though wind conditions remain split (45% good, 55% bad). The peak swell period extends through September, with September delivering the largest waves at 1.5m, though wind conditions are less favorable (only 39% good). For a balance of swell size and cleaner winds, November is a strong contender, as swell quality remains high (97% ground swell, 1.1m) and wind conditions improve slightly (49% good). December through March are also solid, with consistent ground swells and manageable sizes (0.9m–1.1m), but wind conditions are often tricky (45–47% good). May through August see bigger swells (1.4m) but suffer from more onshore winds (only 39–40% good days). Overall, advanced surfers may prefer the larger swells of April–September despite wind variability, while those prioritizing cleaner conditions might target November or the early season months when winds are slightly better.

July at Sunzal offers consistent surf with an average swell height of 1.4m and a solid 14.4s period, delivering powerful, well-spaced waves. The swell is predominantly from the SSW (52.4% of waves in the 1-1.5m range, 21.93% in the 1.5-2m range), providing clean, rideable lines ideal for intermediate to advanced surfers. Smaller contributions from the S and SW directions add variety, though larger sets (2-2.5m) are rare. Wind conditions are favorable 40% of the time, with light to moderate breezes from the NNE to SE (mostly 10-20kph) offering offshore or cross-offshore flow early in the day before occasional onshore tendencies kick in. Stronger winds (20-30kph) from the SSW can occasionally degrade conditions, but July generally provides reliable, medium-sized waves with good shape and minimal wind disruption—best suited for those comfortable with slightly overhead, well-defined walls.
