Praia da Vieira - surf spot statistics

Praia da Vieira benefits from consistent ground swells throughout the year, but the best conditions for surfers typically occur from October through March. During these months, the swell is primarily ground swell-driven (65-92%), which produces cleaner, more powerful waves compared to the wind swell-dominated summer months. The mean swell size peaks in winter, averaging 2.1-2.5m, offering ideal conditions for intermediate to advanced surfers. Wind conditions are also more favorable in these months, with good wind days occurring 31-37% of the time, though offshore winds are still relatively scarce compared to other surf spots. The period from November to February stands out as the peak season, with December and January providing the largest swells (2.3-2.5m) and the highest likelihood of clean conditions. The summer months (May-August) see a significant drop in ground swell influence (14-39%), with smaller waves (1.4-1.6m) and predominantly poor wind conditions (78-85% bad winds), making them less reliable for quality surfing. September and October serve as transitional months, where ground swell begins to increase again, offering improving conditions. For surfers seeking the most consistent, powerful waves with the best wind alignment, targeting the winter months is recommended, while summer sessions are best suited for beginners or when small, wind-dependent swells prevail.

October at Praia da Vieira offers decent surfing conditions with an average swell height of 1.9m and a solid period of 11.4s, indicating consistent, well-formed waves. The dominant swell direction is from the WNW and NW, contributing to 10–12% of waves in the 1.5–2.5m range, with occasional larger sets. Wind conditions are favorable for surfing 33% of the time, predominantly from the N to NW quadrant, though stronger winds (20–30kph) from the N and NNW can occasionally create choppy conditions. Expect the most rideable waves when winds are light to moderate (under 20kph), particularly with offshore components from the NE to E. The spot handles mid-sized swells well, offering a mix of power and shape, though larger days can get unruly if winds turn onshore. Overall, October provides reliable surf with good energy, best suited for intermediate to advanced surfers.
