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.

August at Vairao, Tahiti, offers consistent surf conditions with an average swell height of 2.1m and a solid period of 12.8s, indicating powerful, well-spaced waves. The swell direction is predominantly from the SSW, S, and SSE, delivering clean, rideable waves with a high frequency of mid to large sizes (1.5m–2.5m+). The largest waves (over 2.5m) are less common but do occur, particularly from the SSW direction, which dominates the bigger swell range. Wind conditions are favorable for surfing 41% of the time, with the most ideal winds coming from the NE to E quadrants at light to moderate speeds (10–20kph). However, stronger onshore winds (ESE–SE) can occasionally disrupt conditions, especially when paired with larger swells. Overall, August is a reliable month for experienced surfers, offering powerful, well-formed waves with a mix of clean and challenging wind conditions.
