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 September, Vairao, Tahiti, offers solid surfing conditions with an average swell height of 2.1m and a favorable average period of 13.0s, suggesting well-formed, powerful waves. The swell direction is predominantly from the south to southwest, with the highest frequency in the SSW sector (18.05% for 1.5-2m waves and 13.75% for 2-2.5m), providing consistent, rideable surf. The wind is ideal for surfing 43% of the time, mostly light to moderate (10-30kph) from the east to southeast, which can help groom the waves. However, stronger easterly winds (30-50kph) occasionally occur, potentially creating choppy conditions. Overall, September delivers reliable waves with good shape and power, though wind conditions can be variable. Advanced surfers will find the most success on days with lighter offshore or side-offshore winds.
