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.

In March, Vairao, Tahiti, offers decent surf conditions with an average swell height of 1.7m and a solid period of 13.2s, providing well-organized, powerful waves. The dominant swell directions are from the south-southwest (SSW), south (S), and southeast (SE), with SSW swells delivering the most consistent and significant waves—peaking in the 1.5-2m range (22.46%) and 2-2.5m range (9.75%). This creates reliable, punchy waves suitable for intermediate to advanced surfers. Winds are favorable 54% of the time, with the best conditions occurring when light to moderate easterlies (E, ESE) or northeasterlies (NE, ENE) prevail, keeping the surface clean. However, stronger easterly winds (10-30kph) can occasionally disrupt conditions, particularly in the afternoons. Overall, March is a solid month for surfing here, with a good mix of size, power, and rideable days—especially when the SSW swells align with lighter winds.
