Vairao - surf spot statistics

Vairao, Tahiti, offers consistent surf year-round, with a strong dominance of ground swell making up the majority of swell energy in all months, peaking at 89% in March and remaining above 75% even in the least favorable months. The mean swell size is most powerful from May to September, averaging 2.1-2.2 meters, providing solid overhead conditions ideal for experienced surfers. Wind conditions are most favorable from February to April, with good wind probability at around 50-54%, making this stretch the best window for clean surf. March stands out as the optimal month, combining high ground swell consistency (89%), decent swell size (1.7m), and the year’s highest likelihood of favorable winds (54%). The second half of the year, particularly June to September, brings larger swells but suffers from increased onshore wind interference, dropping good wind probabilities below 45% in peak swell season. Despite bigger waves, wind reliability decreases, making late-season sessions more hit-or-miss. For a balance of size, swell consistency, and cleaner conditions, late southern hemisphere summer (February-April) is the prime time for Vairao. Early season (January) and late season (October-December) see slightly smaller waves (1.6-1.9m) and mixed wind conditions, but still deliver surfable days with fewer crowds. December is the least consistent, with higher wind swell influence (25%) and weaker ground swell dominance (75%). While Vairao is rarely flat (0% "no swell" days year-round), wind management is key—target the March-April sweet spot for the highest chance of epic sessions.

October in Vairao, Tahiti, delivers solid surf conditions with an average swell height of 1.9m and a strong 13.0s period, offering clean, well-spaced waves. The dominant swell direction is from the SSW, which accounts for nearly 50% of the waves in the 1.5-2.5m range, making it the most productive direction for quality surf. The SE to SW quadrants also contribute consistently, ensuring a good variety of rideable waves. Wind conditions are favorable 46% of the time, primarily light to moderate (10-30kph) from the ENE to SE, which can groom the waves for clean faces. However, stronger easterly winds (20-40kph) occasionally occur, potentially creating choppier conditions. Overall, October provides reliable, powerful waves with a high chance of good surfing sessions, especially when the wind cooperates. Intermediate to advanced surfers will find the most enjoyment here, thanks to the combination of size, period, and manageable winds.
