Manazillo Bay - surf spot statistics

Manzanillo Bay, Mexico, offers consistent surf conditions year-round, with ground swells dominating every month—no wind swell or flat days to worry about. The best months for surfers are typically from November to March, when good wind conditions peak (66-73% favorable) and swell sizes remain manageable (0.9-1.2m), making for clean, rideable waves. Winter months see smaller but more reliable swells, ideal for intermediate surfers. April to September brings larger swells (1.3-1.6m), but wind conditions deteriorate significantly, with onshore winds becoming more frequent (56-83% bad winds). June through August is particularly challenging, with the highest swell energy but the worst wind setups. October marks a transition, with improving winds (62% good) and solid swell size (1.5m), making it a decent shoulder-season option. For the most balanced experience—consistent ground swells, favorable offshore winds, and comfortable swell heights—focus on November through February. Advanced surfers chasing bigger waves might tolerate the less favorable winds in late spring and summer, but overall, winter provides the most user-friendly conditions.

In July, Manazillo Bay offers consistent surf conditions with an average swell height of 1.4m and a long-period swell of 15 seconds, producing clean, well-spaced waves ideal for intermediate to advanced surfers. The dominant swell direction is from the SSW, with the majority of waves falling in the 1-1.5m range (42.1%) and 1.5-2m range (26.11%), ensuring rideable conditions most of the time. Larger sets occasionally reach up to 2.5m, though they are less frequent. Wind conditions are variable, with only 17% of days providing ideal offshore winds—typically light easterlies or variable breezes early in the day. The prevailing winds come from the SW, often picking up to 20-30kph (9.29% frequency), which can create choppier conditions by midday. For the best sessions, aim for mornings when winds are lighter and swells are peaking from the SSW. Overall, July delivers reliable surf with good power and shape, though wind management is key for optimal conditions.
