Huntington Beach - surf spot statistics

Huntington Beach offers surfable conditions year-round, but the best months for consistent waves and favorable winds are typically from November through March. During this period, ground swell dominates with percentages ranging from 60% in December to 75% in March, providing more reliable and cleaner waves compared to wind swell. The mean swell size is modest, averaging 0.7m to 0.9m, but the reduced wind swell interference makes for better-quality rides. Wind conditions are less ideal in winter, with bad winds occurring 62-73% of the time, but there are still decent windows when offshore winds (good wind conditions around 27-38%) help shape the waves. Late fall and early spring (October, November, March) can be particularly good as they balance swell consistency with slightly improved wind chances. Summer months (May-September) see the highest ground swell percentages (82-86%), but the waves are often smaller (0.7m-0.9m) and plagued by bad onshore winds (84-86% of the time), making sessions less predictable. Overall, late fall to early spring provides the best compromise between swell energy and occasional clean conditions, while summer is more hit-or-miss despite higher ground swell frequency. Swell direction and local bathymetry play a role too, but statistically, November through March is the prime window for surfers prioritizing quality over frequency.

December in Huntington Beach typically offers surfable conditions, though they lean toward smaller and inconsistent swells. The average swell height is 0.7m with a solid 13.2s period, indicating decent energy despite the modest size. Most waves are in the 0.5-2m range, primarily from the SSW to W directions, with the best contributions coming from S, SSW, SW, WSW, and W. These swells produce the majority of rideable waves, though larger sets above 1.5m are infrequent (peaking around 1–2% of the time). Wind conditions are favorable for surfing 34% of the time, with lighter winds (under 20kph) being most common. Offshore or light cross-shore winds (N, NE, ENE) occur occasionally but are outweighed by onshore flow (W, WSW, SW). Expect smaller, clean days when winds cooperate, but prepare for blown-out chop when stronger onshore winds prevail. Overall, December delivers a mix of smaller, manageable waves with occasional mid-sized pulses—best suited for shortboarders or those happy with waist-high to head-high peaks.
