Peahi-Jaws - surf spot statistics

Peahi (Jaws) is a world-class big-wave surf spot, heavily dependent on powerful ground swells and favorable winds. The best conditions occur during the winter months, particularly from December to February, when ground swell dominates (71-82%) with mean swell sizes averaging 2.5-2.6m, providing the massive, clean waves Jaws is known for. Wind conditions, however, are challenging year-round, with only 23-30% of days offering good offshore or light winds in peak swell season. Winter months still have the best balance, despite high percentages of unfavorable winds (70-77%). From March onward, ground swell frequency declines, with wind swell becoming dominant by April, leading to smaller, less consistent waves (1.6-2.1m). Summer (June-August) sees the worst conditions, with minimal ground swell (10-12%), mostly wind chop, and poor wind patterns (81-83% bad winds). A slight improvement occurs in September-October as ground swell returns (28-51%), but wave size remains modest (1.6-1.9m). For expert surfers targeting Jaws' legendary barrels, the ideal window is December-February, when the largest, cleanest ground swells arrive, despite frequent onshore winds requiring patience for perfect days. The rest of the year is either too small or too wind-affected for Jaws to truly awaken.

In February, Peahi (Jaws) offers powerful and challenging conditions suited for experienced surfers. The average swell height is 2.5m with a solid 12.6s period, indicating consistent, well-spaced waves. The dominant swell directions are NW and NNW, contributing to the majority of waves over 1.5m, particularly in the 2-2.5m range (16.4% from NW, 6.05% from NNW), with a notable portion exceeding 2.5m (1.67% from NW). ENE and E swells also play a role, producing sizable waves with significant energy. Wind conditions are favorable for surfing 29% of the time, with lighter winds (0-20kph) from the NNE to NE directions being most common. However, stronger E and ENE winds (20-50kph) occur frequently, potentially causing choppy conditions. The spot’s exposure to large NW swells and occasional crosswinds makes it best for advanced surfers seeking heavy, barreling waves. Optimal sessions will coincide with lighter NE winds and NW swells, but preparation for strong winds and powerful surf is essential.
