Stone Harbor - surf spot statistics

Stone Harbor offers fairly consistent surf conditions year-round, though the best months for surfers tend to be September through November due to a higher percentage of ground swell (peaking at 21% in September) and relatively decent wind conditions (23% good winds in September). While wind swells dominate this spot year-round (typically 60-75%), the fall season brings a slight increase in cleaner ground swells, which often produce better wave shape and consistency. Swell size averages around 0.8m during these months, which is manageable for most surfers, though not large. Winter (December-February) sees similar swell sizes but suffers from poor wind conditions (83-85% unfavorable), making sessions less reliable despite decent swell presence. Spring and summer (April-July) have higher chances of no swell (peaking at 29% in July) and generally smaller waves (0.6-0.8m), though wind conditions improve slightly (19-24% favorable). Summer months, particularly June and July, offer the highest likelihood of good winds but suffer from weaker, wind-driven swells. Overall, advanced surfers should target September for the best mix of swell energy and cleaner conditions, while beginners may find smaller summer waves more approachable despite the inconsistent wind alignment.
