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.

October in Manzanillo delivers consistent surf with an average swell height of 1.3m and a solid 14.3s period, offering well-organized, powerful waves ideal for intermediate to advanced surfers. The primary swell directions are SW (51.86% in the 1-1.5m range) and SSW (20.19%), ensuring clean, angled waves with good shape. Larger sets occasionally reach 2.5m, particularly from the SW (12.41% at 1.5-2m), providing more challenging sections for experienced riders. Wind conditions are the main variable—while 36% of the time it’s clean (offshore or light), ENE trade winds (11.88% at 20-30kph) can create bump on occasion, especially mid-morning. Early sessions often capitalize on lighter winds, while afternoons may see textured conditions. Overall, October is a reliable month for quality surf, with the best days combining SW swells and lighter SSW/SSE winds. Pack your step-up board for bigger days, and expect mostly shoulder-head high waves with occasional overhead+ pulses.
