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.

In September, Manzanillo, Nicaragua, offers consistent surf conditions with an average swell height of 1.4m and a strong, well-spaced period of 14.3s, indicating powerful, clean waves. The swell is predominantly from the SW (42.58% in the 1-1.5m range) and SSW (24.83% in the same range), with occasional larger sets up to 2.5m, particularly from the SW direction. This makes for high-quality, rideable waves with good shape and energy. Wind conditions are variable, with ideal surf winds (light offshore or sideshore) occurring 33% of the time. However, ENE winds (20-30kph) are common, which can create choppier conditions. The best sessions will likely be early mornings when winds are lighter, as afternoon onshores may impact wave quality. Advanced surfers will find the most opportunities, especially when the SW swell peaks. Overall, September delivers solid, powerful surf with a mix of clean and wind-affected conditions—timing is key for optimal sessions.
