Steamer Lane is a consistent surf spot with year-round swell, but the best conditions typically occur during the winter months from November through February. During this period, ground swell dominates (87-95%), delivering powerful, well-organized waves with mean swell sizes ranging from 1.7m to 2.4m. December and January stand out as prime months, offering the largest waves (2.4m and 2.1m respectively) and the highest likelihood of clean, ground-swell-driven surf. Wind conditions, however, are less favorable in winter, with bad winds (onshore or strong crosswinds) occurring 77-79% of the time, but the sheer quality of the swell often compensates for this. Spring (March-May) sees a gradual drop in ground swell influence (58-79%) and swell size (1.7-1.9m), while wind conditions remain poor (81-85% bad). Summer (June-August) is the least reliable season, with wind swell taking over (63-74%) and smaller waves (1.2-1.5m), though wind conditions improve slightly (21-24% good). Fall (September-October) marks a return of ground swell dominance (63-82%) and slightly better wind chances (22% good), making it a solid alternative to winter for surfers seeking more manageable conditions. Overall, advanced surfers will find the biggest and cleanest waves at Steamer Lane in late fall and winter, while summer offers smaller, less predictable surf with more mixed wind conditions.
