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.

January at Peahi (Jaws) delivers powerful, big-wave conditions, with an average swell height of 2.6m and a strong 13s period, ideal for expert surfers seeking heavy waves. Swells predominantly arrive from the NW and NNW, with the largest waves (over 2.5m) accounting for 2.12% and 0.53% of occurrences, respectively. Mid-range swells (2-2.5m) are frequent, especially from the NW (14.82%) and NNW (5.95%), ensuring consistent, high-energy surf. Wind conditions are less favorable, with only 30% of days offering ideal offshore or light cross-shore winds—typically from the NE to E sectors. However, stronger onshore winds (20-50kph) from the E to ESE are common, creating choppy or blown-out conditions. This spot is strictly for advanced riders, as winter swells produce massive, fast-moving waves with significant power. Wind windows are critical here—the best sessions occur when NE or E winds remain light, allowing the famed Jaws barrels to clean up. Expect challenging paddle-outs, strong currents, and heavy wipeouts in January.
