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 July, Vairao, Tahiti, offers solid surf conditions with an average swell height of 2.2m and a strong average period of 12.8s, indicating powerful, well-formed waves. The swell direction is predominantly SSW, contributing to sizable waves in the 1.5–2.5m range, with a notable 15.69% of swells reaching 2–2.5m from this direction, suggesting consistent overhead surf. Wind conditions are favorable 39% of the time, with lighter breezes (0–20kph) from the NNE to ESE being most common. However, stronger winds (20–50kph) from the E to SE can occasionally disrupt conditions, particularly when combined with larger swells. The spot’s exposure to SSW swells and generally manageable winds makes it a reliable choice for experienced surfers, though wind direction variability means checking daily forecasts is advisable for optimal sessions. Overall, July delivers powerful, clean waves with occasional wind challenges.
