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.

December at Vairao, Tahiti, delivers consistent surf with an average swell height of 1.6m and a solid period of 12.2s, ensuring well-formed, powerful waves. The primary swell direction is southerly, particularly SSW (32.2% of waves between 1-2.5m), which aligns best with the spot, offering clean, rideable conditions. SE and S swells also contribute significant energy, though slightly less organized. Wind is favorable 47% of the time, predominantly light to moderate (0-20kph) from ENE to ESE, keeping surfaces clean. Stronger winds (20-30kph) from E/ESE occur but are less frequent. Expect a mix of mid-sized (1-2m) and larger (2-2.5m) waves, with SSW swells generating the most ideal, punchy peaks. Overall, December provides reliable surf with good power and decent wind conditions, best suited for intermediate to advanced surfers.
