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.

March in Manzanillo delivers consistent surf with a solid average swell height of 1.2m and a quality 13.5s period, providing well-spaced, powerful waves. The primary swell direction is from the SW to SSW, accounting for roughly 60% of all waves, with SW swells dominating (29.99% of waves in the 1-1.5m range). These swells often produce clean, rideable conditions, especially when paired with the 21% chance of ideal offshore winds. Wind patterns are mixed—ENE winds (20-40kph) are prevalent, which can create chop, but lighter winds from the W/SW occasionally clean things up. Expect the best sessions when SW swells align with lighter winds, offering shoulder-high waves with good shape. While strong ENE winds can disrupt conditions, March still provides reliable surf with enough good days for advanced riders to score quality waves.
