Mavericks - surf spot statistics

Mavericks, known for its powerful and often dangerous waves, offers the best surfing conditions during the winter months, particularly from November through February. During this period, ground swell dominates, with percentages ranging from 87% in November to 93% in January, ensuring consistent, high-quality waves generated by distant storms. The mean swell size peaks at 1.9m in January and February, dropping slightly to 1.8m in December, which is ideal for experienced surfers seeking challenging surf. Wind conditions are most favorable in January and December, with good winds occurring around 50% of the time, though February sees a dip in favorable winds (42%). Outside these months, wind conditions deteriorate significantly, with bad wind frequencies above 50% from March onward, peaking at 89% in July. Swell quality declines noticeably in spring and summer, with ground swell percentages dropping as low as 50% in June and wind swell becoming more prominent, leading to less predictable and generally smaller waves (1.0m–1.5m). September and October mark a transitional period, with improving ground swell (71%–82%) and marginally better wind conditions (21%–36%), but still fall short of winter’s consistency. For surfers targeting Mavericks’ legendary waves, the prime window is clearly winter, when large, clean ground swells and relatively manageable wind conditions combine to create world-class surf.

April at Mavericks tends to deliver manageable but often inconsistent conditions for surfers, with an average swell height of 1.5m and a solid 12.6s period, indicating decent energy in the waves. The dominant swell direction is from the west, contributing the majority of rideable waves, particularly in the 1-2.5m range, with a notable presence of larger sets (2-2.5m at 8.45%). However, the spot sees fewer truly big days in April, with waves over 2.5m being rare. Wind conditions are somewhat hit-or-miss, with only 23% of days offering ideal offshore or light winds. The most problematic winds come from the northwest and west-northwest, frequently bringing stronger onshore or cross-shore breezes (20-30kph range), which can degrade wave quality. For experienced surfers, April can still offer good sessions, particularly when the westerly swells align with lighter winds—but patience and timing are key, as conditions often fluctuate between clean, mid-sized days and wind-affected chop.
