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.

Peahi (Jaws) in May typically offers moderate swell conditions with an average height of 1.7m and a decent period of 9.4s, suggesting relatively clean, well-spaced waves. The swell predominantly arrives from the northeast to east-northeast, accounting for the majority of surfable waves (1–2.5m), with the largest contributions coming from ENE and E directions. These swells produce some solid sets, particularly in the 1.5–2.5m range, which make up a significant portion of the swell distribution. However, true big-wave conditions (over 2.5m) are rare in May, occurring only about 0.1–0.2% of the time. Wind conditions are less favorable, with onshore easterlies (E–ENE) dominating, frequently blowing in the 20–40kph range, which can create choppy or textured surfaces. Clean offshore winds (ideal for Jaws’ massive waves) are scarce, occurring just 20% of the time. When winds do swing offshore (NW–NNW), they’re usually light to moderate (10–30kph), offering brief windows of groomed conditions. Overall, May is a transitional month here—smaller than winter’s giants but with occasional punchy swells. Experienced surfers will find rideable waves, but wind inconsistency means patience is key for scoring clean sessions.
