Hermosa Beach - surf spot statistics

Hermosa Beach offers relatively consistent swell conditions year-round, with ground swells dominating most months, particularly from June through September, where they account for 79-82% of the swell activity. The mean swell size hovers between 0.7m and 0.9m, peaking in winter (November to February) with slightly larger waves. However, wind conditions are often unfavorable, with the highest likelihood of bad winds occurring from April to September, when onshore winds prevail 74-81% of the time. The best balance between swell consistency and manageable winds appears in late fall and early winter (October to December), where ground swells remain solid (63-77%), and wind conditions improve slightly with good winds reaching 29-34%. January and February also see decent ground swells (72-73%) but still suffer from higher bad wind probabilities (63-65%). Summer months (June-August) bring the cleanest ground swell dominance (79-81%) but are plagued by poor wind conditions (79-81% bad winds), making the waves choppy and less ideal. For surfers prioritizing quality, late fall and early winter offer the most promising combination of reliable swell and slightly better wind odds, though patience for favorable wind days is key.

March at Hermosa Beach offers generally manageable surf conditions with an average swell height of 0.9m and a solid 12.8s period, suggesting well-spaced, clean waves. The swell direction is predominantly from the W and WSW, with about 60% of waves falling in the 0.5-1.5m range—ideal for intermediate surfers. Larger sets (1.5-2.5m) occur 7-8% of the time, providing occasional challenge. Wind conditions are a mixed bag: while 29% of days see favorable offshore or light winds (typically morning E/NE), the afternoons often bring onshore WSW/W winds (10-20kph+), which can chop up the surface. Optimal sessions are most likely early in the day when winds are lighter. Expect smaller, weaker waves when swells shift SW/SSW. Overall, March delivers fair to good surf, with the best days coinciding with W swells and morning glass-offs.
