Waikiki Beach - surf spot statistics

Waikiki Beach is known for its relatively consistent surf, but the conditions vary throughout the year. The best months for surfing at Waikiki are generally from September through May, when ground swells dominate and swell size remains steady around 1.3-1.4m. Ground swells, which provide cleaner and more organized waves, are most prevalent from September (67%) to May (65%), peaking in September and May. Wind conditions, however, are less favorable overall, with only 9-21% of days offering good winds across the year—lowest in June (9%) and highest in January (21%). The worst wind conditions occur from April to August, when bad winds exceed 85% of the time. Swell consistency is excellent year-round, with no days registering as flat. December and November see a more balanced mix of ground and wind swells (50-51% ground swell), but winds remain predominantly onshore. For the best balance of swell quality and slightly better wind chances, target September, October, or May, when ground swell percentages are high (62-67%) and wind conditions are marginally better compared to summer months. Summer (June-August) tends to be the least favorable due to stronger onshore winds and a slight drop in ground swell dominance. While Waikiki is surfable year-round, the fall and early winter months offer the most reliable conditions for experienced surfers.

November at Waikiki Beach offers generally user-friendly surf conditions with an average swell height of 1.4m and a consistent period of 11.0s, providing clean, ridable waves. The swell direction is predominantly ENE (23.8% of waves in the 1-2.5m range), which aligns well with the break, generating smooth, peeling waves ideal for longboarding and intermediate surfers. Smaller swells from NNE to NE also contribute, though larger swells (>2m) are rare, occurring just 1-3% of the time. Wind conditions are less favorable, with only 17% of days offering ideal offshore or light winds (typically from the W to NNW); ENE trade winds (10-30kph) prevail, creating bumpy conditions on 40+% of days. Expect a mix of knee-high to head-high waves, with the best sessions occurring when ENE swells coincide with lighter W/NW winds. Crowds are likely due to the consistent conditions, but patience rewards quality rides.
