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.

April at Peahi (Jaws) delivers a mix of conditions for advanced surfers, with a predominant swell direction from the northeast to east-northeast, contributing to the spot’s powerful, clean waves. The average swell height is 2.1m with a solid 10.5s period, ensuring strong, well-formed waves. The most consistent swells arrive from ENE, E, NW, and NNW, with heights frequently in the 1.5–2.5m range (peaking at 6–8% occurrence), while larger sets over 2.5m are rare but possible (0.1–0.3%). Wind conditions are less favorable, with only 17% ideal for surfing—primarily light offshore NW or NNW winds (10–20kph). Unfortunately, onshore E-ENE winds (20–40kph) dominate 23–30% of the time, creating choppy or blown-out conditions. For big-wave chargers, the best windows come when NE-ENE swells coincide with lighter NW winds, but expect challenging wind interference on most days. This is a month for skilled surfers prepared to wait for the right combo of swell and wind.
