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.

July at Zuma Beach typically offers small but consistent surf, with an average swell height of 0.7m and an excellent average period of 15.4s, indicating clean, well-spaced waves. The dominant swell direction comes from the SSW and SW, with the majority of waves falling in the 0.5–1m range (83% of the time), occasionally reaching 1–1.5m (4.2%). Larger swells over 1.5m are rare, making conditions ideal for longboarders, beginners, or surfers looking for mellow, user-friendly waves. Wind conditions are favorable for surfing 42% of the time, with lighter breezes (below 20kph) most common from the NNE and NE. However, stronger winds (20–30kph) can occasionally disrupt conditions, particularly from the NNE and S directions. Overall, July delivers small, clean waves best suited for relaxed surfing, though advanced surfers may find the lack of size limiting. Morning sessions often provide the cleanest conditions before any afternoon wind interference.
