Zuma Beach - surf spot statistics

Zuma Beach is a consistent surf spot with year-round swell activity, but the best conditions for surfers generally occur between April and September. During these months, ground swell dominates (90-97%), providing cleaner and more organized waves compared to wind swell, which is minimal (1-9%). The mean swell size hovers around 0.7-0.9m, offering manageable but often small to mid-sized waves, making it ideal for beginners and longboarders. Wind conditions improve significantly in this period, particularly from May to September, where good wind days (offshore or light winds) range from 41-53%, peaking in August. The worst wind conditions are in winter, especially December, where bad winds (onshore or strong crosswinds) reach 83%. Winter months (November-February) see more mixed swell conditions with higher wind swell percentages and frequent bad wind days, though ground swell remains fairly consistent. Swell size doesn’t vary drastically throughout the year, but the combination of cleaner ground swell and favorable winds makes late spring to early fall the prime window for surfing Zuma Beach. If you prefer smaller, cleaner waves with higher consistency, target May through September, while winter offers more size but less predictable conditions due to increased wind interference.

In March, Zuma Beach offers generally manageable surf conditions with an average swell height of 0.8m and a solid period of 14.1s, indicating well-spaced, clean waves. The dominant swell directions are WSW (33.7% between 0.5-1m) and SW (21.97% in the same range), while larger waves (1-1.5m) are less frequent but possible from WSW (7.29%) and W (5.57%). Wind conditions are variable, with only 28% of the time being ideal for surfing, as onshore winds (W, WSW, SW) occasionally disrupt the lineup. Stronger winds (20-30+ kph) are most likely from N, NNE, and NW directions, which can create choppy conditions. Overall, expect small to mid-sized, long-period waves with variable wind interference—best sessions occur when winds are light or offshore (E/ENE, rare in March). Advanced surfers can capitalize on the occasional larger sets, but beginners may find the conditions inconsistent.
