Topanga Beach - surf spot statistics

Topanga Beach is a surf spot with relatively modest conditions year-round, but the best months are typically during the spring and early summer when ground swells are most consistent and wind conditions improve slightly. The highest likelihood of ground swell occurs from April to September, peaking in May with 81% ground swell presence and the lowest incidence of no swell (13%). However, wind conditions remain challenging throughout the year, with bad winds (onshore or cross-shore) prevailing over 70% of the time. The most favorable balance between swell and wind occurs in April and September, where ground swell percentages remain high (71% and 73%, respectively) while good wind conditions reach their highest probabilities (30% in April, 28% in September). Swell size averages around 0.6 to 0.7 meters, with slightly larger waves in April and May. Late fall and winter months (November to February) see a steep drop in ground swell consistency, with higher no-swell days and worsening wind conditions, making them less ideal for surfing. If forced to choose, April stands out as the best month, offering a strong ground swell presence and marginally better winds. However, surfers should temper expectations—Topanga isn’t a big-wave destination, and wind quality remains a limiting factor even in optimal months.

In February, Topanga Beach experiences predominantly small to moderate waves, with an average swell height of 0.6m and a decent 13.5s period, indicating well-spaced, consistent energy. The majority of waves come from SW and WSW directions, contributing to rideable conditions, especially in the 0.5-1.5m range, which occurs frequently. Larger swells (1.5-2.5m) are less common but present when WSW swells align. Wind conditions are variable—ideal for surfing about 25% of the time, typically when lighter winds from the E/NE minimize chop. Stronger onshore winds (SW/W) can occasionally degrade quality, but the extended period helps maintain shape. Overall, expect smaller, clean waves early in the day with occasional mid-size swell windows offering good rides for those patient with conditions.
