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.

June at Peahi (Jaws) typically offers smaller and less consistent swell compared to the winter season, with an average swell height of 1.6m and a moderate period of 8.6s. The dominant swell direction is ENE, contributing the largest share of rideable waves, particularly in the 1–2.5m range, with ENE and E swells accounting for the majority of mid-sized and larger waves (1.5–2.5m). NW and NNW swells also occasionally provide surfable conditions but are far less frequent. Wind conditions are often challenging, with easterly winds (E, ENE) dominating and frequently blowing at 20–40kph, creating onshore or cross-onshore conditions that degrade wave quality. Only 18% of the time are winds favorable for surfing, typically when lighter or from more favorable directions. Overall, June is not the prime season for Jaws, as the swell tends to be smaller and less powerful, while wind conditions are often less than ideal. Advanced surfers may find occasional clean sessions, but expectations should be tempered compared to the massive winter swells this break is known for.
