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.

January at Vairao, Tahiti, offers solid surf conditions with a mix of consistency and quality. The average swell height is 1.6m with a favorable 12.5s period, providing well-spaced, powerful waves. Most swells come from the SSW (dominating 10.46% in the 1-1.5m range and peaking at 14.22% for 1.5-2m), followed by SW and S directions, ensuring a steady supply of rideable waves. Waves in the 1-2.5m range are frequent (over 30% combined), making it ideal for intermediate to advanced surfers, while smaller or larger swells are rare. Wind conditions are cooperative 48% of the time, with light to moderate easterly trades (ENE-E at 8-20kph) being the most common but occasionally blowing stronger (20-30kph). Offshore winds (W-WSW) are infrequent but provide cleaner conditions when they occur. Expect a mix of lumpy and groomed waves, with the best sessions likely when winds stay below 20kph. Overall, January delivers reliable surf with enough size and power for performance turns or barrel opportunities, though wind management is key.
