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 March, Peahi (Jaws) offers powerful surf conditions with an average swell height of 2.4m and a solid 11.9s period, indicating well-spaced, high-energy waves. The dominant swell directions are NW, NNW, and ENE, with the biggest waves (over 2.5m) most frequently arriving from NW (14.05% in the 2-2.5m range, plus 0.87% overhead). Smaller but still notable contributions come from ENE and E swells. Cross-shore or light onshore winds are ideal for surfing here, but favorable wind conditions occur only 23% of the time. The wind distribution shows stronger easterlies (E-ENE) with speeds often 20-40kph, which may create choppy conditions unless local wind protection is present. Given the spot’s exposure, March delivers heavy, fast-moving waves suitable only for expert surfers and tow-in specialists, especially when NW swells align with lighter winds. Expect raw power and occasional XL days, but be prepared for challenging wind patterns.
