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.

In October, Waikiki Beach offers generally favorable surf conditions with an average swell height of 1.3m and a solid period of 11.9s, producing clean, well-formed waves. The swell direction is most consistent from the ENE, NE, and SSW, with the majority of waves in the 1-1.5m range (8.98% ENE, 4.77% NE, 15.50% SSW), occasionally reaching 1.5-2m (7.58% ENE, 4.91% NE). Larger swells over 2m are rare, making conditions manageable for most skill levels. Wind quality is variable—only 18% of the time is it ideal (typically light offshore or sideshore from N to ENE). However, ENE winds (10-30kph) prevail, which can cause choppiness, especially at higher speeds. The best sessions occur when winds are lighter (<20kph) from NNE or NNW, keeping waves clean. Overall, October is a reliable month for surfers, with a mix of playful mid-size waves and occasional bigger sets, though wind conditions require careful timing.
