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.

June at Vairao, Tahiti, offers solid surfing conditions with a consistent, powerful swell. The average swell height is 2.2m, paired with a long 13.2s period, producing well-spaced, clean, and powerful waves—ideal for intermediate to advanced surfers. The swell predominantly comes from the S to SSW direction (peaking at SSW with 14.26% in the 1.5-2m range and 16.77% in the 2-2.5m range), ensuring well-structured waves with good energy. While smaller swells (1-2.5m) are frequent, larger swells over 2.5m are rarer but present, providing occasional challenge. Wind conditions are favorable 45% of the time, typically light to moderate (below 20kph) from the NE to SE sectors, which keeps the surface clean. However, stronger onshore winds from the E to ESE (occasionally exceeding 30kph) can occasionally degrade conditions. Overall, June delivers consistent, high-quality waves with a mix of manageable and heavier sets, especially when wind aligns offshore or sideshore—opt for early sessions when winds are lighter.
