Peahi-Jaws seasonal overview
Best Surf Season (October - March)
From October through March the North Pacific storm machine comes alive. Low-pressure systems intensify below the Aleutian Islands and drive long-period NNW, NW and N groundswells into the north-facing reef at Peahi. Average heights hover around 5-7ft (1.5-2.1m), but the real story is the period: 11-13s, sometimes much longer, which turns the outer reef into a heaving, grinding beast. Offshore S/SW wind windows are most reliable in December and January, and when they line up with a solid NNW swell, Jaws delivers some of the most powerful waves on Earth.
Fair Surf Season (April - May and September)
April, May and September are shoulder months. The storm track shifts north and weakens, so pure NNW swell becomes less consistent. The dominant energy swings to NE, ENE and E trade wind swell, which is directional, shorter period and less suited to the north-facing reef. Still, April can get late-season NW pulses, and September often sees the first long-period swells of the new season. These months are for the patient surfer who is willing to wait for an early or late gift from the North Pacific.
Low Surf Season (June - August)
The summer months of June, July and August are Jaws at its most dormant. The North Pacific High pumps relentless E and ESE trade winds, while the only swell on offer is short-period ENE/E wind swell. Average wave periods drop to around 9s and clean offshore wind windows fall to 10-14%. Expect small, bumpy, cross-shore conditions and a reef that is better left to the turtles.
