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 June, Waikiki Beach offers manageable surf with an average swell height of 1.4m and a solid period of 12.3s, providing clean, rideable waves. The dominant swell direction is from the SSW (22% of waves in the 1-1.5m range), followed by S and ENE, ensuring consistent energy. Most waves fall in the 1-1.5m range (59.7%), ideal for intermediate surfers, with 23.4% in the 1.5-2m range offering punchier sections for advanced riders. However, wind conditions are less favorable—only 9% of winds are ideal (light onshore/offshore), while ENE winds (30-40kph) dominate 19.2% of the time, often creating choppy conditions. Swell quality is decent, but wind interference can impact glassiness, especially mid-morning. Early sessions or sheltered spots may provide cleaner rides. Overall, it’s a mixed month: good wave energy but wind-dependent.
