Manzanillo - surf spot statistics

Manzanillo, Nicaragua, benefits from consistent ground swells year-round, rarely experiencing flat days (0% no swell). The best months for surfers are typically from March to October, when ground swell dominates (90–98%) and wind conditions gradually improve. March through June offers reliable 1.2–1.4m swells with slightly better wind percentages (21–31% good), though onshore winds remain a challenge (69–79% bad). Late-season months like September and October stand out, combining strong ground swells (93%) with the year’s best wind conditions (33–36% good). July and August see slightly larger swells (1.4m) but suffer from inconsistent winds (20–25% good). Winter months (November–February) are less ideal due to higher bad wind frequencies (70–85%), despite decent swell size (1.2m). For advanced surfers prioritizing clean conditions, September and October are the prime window—expect manageable winds and consistent, mid-sized swells. However, expect year-round wind volatility, making dawn patrol or sheltered sections the best bet.

August in Manzanillo offers consistent surf with an average swell height of 1.4m and a solid 14.3s period, delivering quality waves. The dominant swell direction is from the SW (38.45% in the 1-1.5m range, 13.85% in 1.5-2m), providing well-organized, powerful waves ideal for intermediate to advanced surfers. SSW swells also contribute with 25.29% in the 1-1.5m range, adding variety. Wind conditions are a mixed bag—while ENE winds (19.31% at 20-30kph) can create choppy conditions, offshore winds are present 25% of the time, mainly from the SW, SSW, and W directions (light to moderate speeds), which clean up the waves. Expect rideable surf most days, with the best sessions occurring when lighter SW or W winds align with the SW swell. Pack your step-up board for bigger days, but overall, August delivers reliable, fun waves with occasional excellent conditions.
