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.

November at Hermosa Beach offers fair to good surf conditions, depending on swell and wind alignment. The average swell height is 0.7m with a solid 13.4s period, indicating well-spaced, clean waves, though on the smaller side. Most swells come from the SW to W directions (peaking around 1-2m), with WSW and W swells contributing the best size and consistency—occasionally reaching overhead range (2-2.5m). However, smaller days (0.5-1m) dominate, making it more suitable for longboarders or beginners unless a solid W swell kicks in. Wind is a mixed bag: offshore (NE-ENE) only 30% of the time, providing ideal glassy conditions, while onshore WSW-WNW winds (10-20kph) frequently create chop. Mornings often see lighter winds, improving chances for clean sessions. Overall, expect fun, manageable waves with some standout days when W swells and favorable winds align. Patience and timing are key.
