Kuta Reef - surf spot statistics

Best Surf Season (April - October)

The heart of the dry season brings a winning combination of steady southeast trade winds and consistent long-period groundswells from the Southern Ocean. During these months, offshore conditions dominate with winds from the E, ESE, and SE quadrant, grooming Kuta Reef's WNW-facing lineup into pristine shape. Swell heights average a solid 1.7 to 2.2 meters with periods regularly exceeding 13 seconds, delivering powerful, rippable waves. This is the prime window for epic sessions when the reef really comes alive.

Fair Surf Season (March & November)

These transitional months sit on the cusp of the monsoon shift. Winds blow more variably, mixing easterly offshores with westerly onshores. Swell quality remains decent—March sees long-period average of 13.3s and November 13.2s—but consistency drops. On calm mornings, clean lines still push through, but be ready for afternoon wind shifts that can flatten the shape.

Low Surf Season (December - February)

The heart of the wet season brings prevailing westerly and northwesterly winds that blow directly onshore at Kuta Reef, chopping up the wave face. Even though the reef still picks up solid 1.6-1.7m swell from the SW and SSW, periods remain in the 12-13s range, the relentless onshore flow makes for difficult, bumpy conditions. Only rare gaps in the monsoon with an easterly breeze offer clean windows—so patience and a keen eye on the forecast are essential.

September: Last Gasp of Glory

September still sees excellent conditions, with 2.0m average swell and 14.3s period. The swell is almost entirely from SSW (70.9%) and S (11.3%), and ideal wind hits 79%—the second-highest of the year. Offshore winds from SE (37.5%) and ESE (36.6%) dominate, with many days of windless, glassy conditions. The surf remains powerful and consistent as the dry season begins its fade. September is a top choice for a reliable, high-quality surf trip.
