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.

October at Peahi (Jaws) delivers prime big-wave conditions, with an average swell height of 1.9m and a powerful 10.9s period, indicating consistent, well-spaced energy. The dominant swell direction is from the north-northwest (NNW), contributing 14.63% of waves in the critical 1.5-2m range and 7.95% in the 2-2.5m range—ideal for advanced surfers seeking sizable, clean walls. ENE and NW swells also bring notable energy, particularly in the 1.5-2.5m range. Wind conditions are less favorable overall, with only 28% of days offering ideal offshore or light cross-shore winds (typically from the E-ENE at 10-20kph). However, strong onshore winds (20-50kph) from the E-ESE are common, creating choppy or unruly surf during 24-30% of the month. For experienced surfers, October is a high-risk, high-reward window: swells are powerful and well-organized, but wind and wave consistency require patience. Sessions are best timed around NNW swells paired with lighter ENE winds—expect heavy, fast drops and demanding paddle-outs.
