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.

November at Peahi (Jaws) brings consistent, powerful swell conditions, making it a prime time for advanced and big-wave surfers. The average swell height is 2.3m with an 11.6s period, indicating well-organized, powerful waves. The dominant swell directions are NNW (19.3% of waves over 1.5m) and NW (13.05% over 1.5m), producing the iconic, heavy barrels Jaws is known for. Swell energy is concentrated in the 1.5-2.5m range (NNW: 18.61%, NW: 12.59%) with a solid chance of bigger sets exceeding 2.5m (NNW: 0.71%, NW: 0.46%). Wind conditions are less favorable, with clean offshore winds (ideal for surfing) occurring only 24% of the time. The prevailing winds are from the E-ENE (20-30kph+ in 27.8% of cases), often creating onshore chop. However, when winds align from the N-NNW (light to moderate in most cases), the wave quality becomes exceptional. This month is for experts only—expect massive, fast-moving waves with challenging wind interplay, requiring precise timing and local knowledge for optimal sessions.
