Nuevo Vallarta - surf spot statistics

Nuevo Vallarta benefits from consistent ground swells year-round, with the highest reliability from January to May when ground swells dominate 92-94% of the time and average swell heights hover around 0.9m. During these months, wind conditions are also most favorable, particularly in January (69% good winds), December (68%), and February (64%), making them the prime window for surfers seeking clean, rideable waves. The swell consistency drops slightly from June to September, with ground swells dipping to 77-80% and no-swell days increasing, especially in July-August when wind conditions worsen (only 46-47% favorable). However, September brings a slight rebound in swell quality (79% ground swells, 0.9m) before improving further in October (86%). Late autumn through early winter (October-December) offers a solid compromise—decent swell consistency (86-89%) and improving winds (58-68% good), though with marginally smaller waves (0.7-0.8m). For ideal surf, prioritize January to February when swell reliability, size, and offshore winds align best, while May onward sees increasing onshore winds and lower consistency, particularly in midsummer (June-August). Advanced surfers may still find workable waves in shoulder seasons (October, April), but the winter months deliver the most optimal balance of power and conditions.

In May, Nuevo Vallarta offers fairly consistent surf conditions with an average swell height of 0.9m and a solid 15.0s period, indicating clean, well-spaced waves. The swell is primarily from the SSW (36.40% in the 0.5-1m range and 15.64% in 1-1.5m) and SW (18.23% in 0.5-1m), producing manageable waves with a good shape. Larger swells (1.5m+) are less common but do occur occasionally, mostly from the SSW. Wind conditions are favorable 51% of the time, with light to moderate speeds (0-20kph) prevailing from the W, WNW, and NW directions. Offshore winds (light NNE to NE) are present around 16-18% of the time, helping to clean up the waves. However, stronger onshore winds (WNW and NW at 10-20kph) can occasionally disrupt conditions. Overall, May delivers fun, waist-to-chest-high waves with good periods, making it a solid month for intermediate to advanced surfers, though bigger days are rare. Early morning sessions often provide the best wind conditions.
